2-factor authorization. Login using two-factor authentication. You can enable two-factor authentication

Two-factor authentication is based not only on the traditional “login-password” link, but also on the additional level of security - the so-called other factor, which must be confirmed in order to deny access to the cloud record or Other data.

The simplest application of two-factor authentication, which is constantly affecting our skin, is through cooking through an ATM. To withdraw money, you need a card that only you have and a PIN code that only you know. Having snatched your card, the criminal cannot withdraw the money without knowing the PIN code, and so he cannot withdraw the money without knowing it, except for the card.

The same principle of two-factor authentication applies to access to your social media accounts, mail and other services. The first official is a combination of login and password, and 5 speeches can act as another.

SMS-kodi

Confirmation for additional SMS codes is very simple. Please enter your login and password, after which an SMS will be sent to your phone number with a code that you need to enter to enter your account. That's all. At the time of entry, another SMS code is sent, which is only valid for the streaming session.

Advantages

• Generation of new skin input codes. If the scammers steal your login and password, they won’t be able to earn anything without the code.
• Linking to the number. It's impossible to enter without a phone.

Nedoliky

• If there is no security signal, you will not be able to log in.
• It is theoretically possible to change the number through the service of the operator or salon service technicians.
• Once you log in and remove the codes on the same device (for example, a smartphone), the protection ceases to be two-factor.

Program-authenticators

This option is quite similar to the first one, with the exception that instead of removing codes via SMS, they are generated on the device with the help of a special add-on (Google Authenticator, Authy). After an hour of setup, you will select the primary key (most often in the form of a QR code), on the basis of which one-time passwords are generated using additional cryptographic algorithms with a duration of 30 to 60 seconds. It’s impossible to assume that criminals will be able to steal 10, 100 or 1,000 passwords and transfer them to someone else who will be the next password.

Advantages

• The authenticator does not require a boundary signal; an Internet connection is sufficient during initial setup.
• Support for multiple cloud records in one authenticator.

Nedoliky

• If criminals deny access to the primary key on your device or through an evil server, they can generate new passwords.
• If the authenticator is installed on the same device from which the login is made, two-factor functionality is lost.

Checking the login for additional mobile add-ons

This type of authentication can be called a hodgepodge of all the previous ones. If you choose to replace codes or one-time passwords, you must confirm the login from your mobile device with the service add-on installed. The device stores a private key, which is verified every time you log in. This works on Twitter, Snapchat and various online games. For example, when logging into your Twitter account in the web version, you enter your login and password, then your smartphone will receive a notification with a prompt about logging in, after confirming it, your page will be displayed in the browser.

Advantages

• There is no need to enter anything before logging in.
• Independence from limits.
• Support for multiple cloud records in one add-on.

Nedoliky

• If evildoers steal your private key, they may get the stink for you.
• The sense of two-factor authentication is used when you use the same device to log in.

Hardware tokens

Physical (or hardware) tokens provide a reliable method of two-factor authentication. Being other devices, hardware tokens are subject to change in most ways, and in any case do not waste your two-factor warehouse. Most often they are represented by USB keys with a power processor that generates cryptographic keys that are automatically entered when connected to a computer. Select a key for a specific service. Google, for example, recommends purchasing tokens based on the FIDO U2F standard, prices for which start at 6 dollars without shipping arrangements.

Advantages

• Daily SMS and add-ons.
• There is no need for a mobile device.
• I’ll use an independent device.

Nedoliky

• It is necessary to bathe the glass.
• Not supported on all services.
• If you change several cloud records, you will have to carry a whole bunch of tokens.

Reserve keys

In essence, this is not a perfect method, but a backup option for the occasional waste or theft of a smartphone, which is used to receive one-time passwords or verification codes. When you set up two-factor authentication with each service, you are given a number of backup keys for use in emergency situations. With their help, you can go to your cloud account, connect the installed devices and add new ones. These keys should be saved in a reliable place, and not by looking at a screenshot on a smartphone or a text file on a computer.

As you can see, there are several nuances to this type of two-factor authentication, but they seem daunting even at first glance. As the ideal combination of protection and handiness may be, the skin determines for itself. However, in any case, all the problems will become too true if you go about the security of payment data or special information that is not visible to others.

You can and should enable two-factor authentication, and you can also read about the services that support it.

Many Internet users have already heard or heard about the two-factor authentication system. Let's talk about this and how to guide us in this article.

Let's first find out what authentication is. If you look at wikipedia, this is the procedure for checking the validity. In real life, such verification may include a passport, finger tapping, eye retina scanning, and so on.

On the Internet, to identify your person, a login and password are required. On almost all sites, to enter a special account, you are asked to provide your login (or email) and password. However, in the end, hackers began to steal this data. The consumption of such data will not be critical, whether it be a game account or a social network. How can such data be stolen from any financial resource? For example, an online bank or exchange. It will be much worse, and for those who do, there will be financial collapse. To uniquely address such situations, an additional defense was invented.

Two-factor authentication, or as it is briefly called 2FA, is a central security feature. In addition to the standard logins and passwords, you need to enter another secret. What secrets will you continue to discover?

Types of two-factor authentication

At the moment, there are many different methods of authorization using 2FA. It is very difficult to find professional ways to understand the basic knowledge of the profession. The truth is simple, but the actions they take are not very reliable. So let's look at these methods in more detail.

This method is used by online banks. You can withdraw a new check from the ATM using passwords. Then, when authorizing on the site, you are asked to enter a password for your new number. This method is Vikoristav Oschadbank. But wait, such a check can be spent or it can be stolen. You may run out of passwords, and it’s a long walk to the ATM. It's not the best way for me. I don’t know, maybe the banks are still vikorist. Write in the comments if you know such a bank.

. At the hour of authorization, you will be sent a one-time password via email, which you will need to enter on the site. As a rule, people do not think about security and during registration they specify passwords such as for email. Therefore, if you steal your data, you can easily enter your password. This method is now more often used as a supplementary one. For example, if you change your IP or make changes in your profile.

One of the most popular, but not the most popular, 2FA method. There are a lot of websites that offer wikis, not only for authorization, but also for renewing your password. SMS notifications have begun to scrounge for an additional subscriber number or viruses for phones. Android phones have the most viruses.

Such keys are used mainly by legal entities to access programs and Internet services. Electronic signatures can also be stored on a flash drive. When purchasing this product, you will see flash drives. This is a reliable method for protection, but not for skin access.

A popular and reliable method of two-factor authentication at the moment. You will download the program to your phone. Synchronize it with the site and the program will generate new passwords within 30 seconds. The program can vikorize a lot of different sites. Data from programs is not forced anywhere, and all information is available only on your phone. However, this method has a minus - it is a waste or a malfunction of the phone. If you don’t pay attention to the nuances we’ll talk about below, then renewing access will be problematic.

Authenticator program for 2FA

Two-factor with additional additions is one of the popular and safe methods at the moment. Using programs for two-factor authentication is very simple. To connect to them you will need:

• Install the program on your phone.
• Synchronize the program with the site by quickly scanning the QR code, which can be scanned by your phone. Or send a special code that will provide an Internet resource.

After starting the program, new passwords will be generated within 30 seconds. The codes are created based on a key that is shared with you and the server. The fragments of the offending warehouse, however, are both for you and for the service, codes are generated synchronously. This algorithm is called OATH TOTP (Time-based One-time Password), and in most cases it is the same that is used.

Almost all add-ons for authentication follow one algorithm. Therefore, you can vikorist those that suit you best. Ale y blame. For example, the Blizzard Authenticator program. There is no way to build under Blizzard and use it for other services.

Adobe also released its own program called Adobe Authenticator. This service allows you to use third-party authenticators. It didn’t dawn on me that I needed to walk my bike.

As practice shows, most IT resources allow the use of any 2FA add-on. And because of any kind of marketing, they want to control this process and create their own program, then most often they allow them to protect not only “their” accounts, but also the cloud records of third-party services.

Therefore, you can choose any authenticator add-on that suits you best, and you will be able to use more services that support 2FA programs.

Popular add-ons for two-factor authentication

Once you check out the 2FA program on Google Play or the Apple App Store, you'll have a wide selection of programs to choose from. And regardless of the new algorithm of work, the advantage is given to the fact that there are additional functions and a manual interface. Below we look at the most popular options.

. It's easiest to use any of the other programs for two-factor authentication. No one has any sense of direction. We will talk about how to work with this program in the next section.

Microsoft also didn’t bother with complexity and made its authenticator even more minimal in appearance. Moreover, Microsoft Authenticator is significantly less functional than Google Authenticator. First of all, if you want all the codes to be displayed, but also the codes from the tokens can be carefully adjusted so that when you run the program, the code appears.

Those are far from the usual programs for two-factor authentication. On the one hand, you don’t need to register immediately - you can start using it with the same ease as Google Authenticator. On the other hand, there are a number of additional possibilities that open up to those who are not willing to go to the adjustment stage.

To enter the program, you can enter a PIN code or fingerprint. Create a backup copy of tokens in Yandex, protected by a password (and here you need to enter your phone number), and update them on any device that is being abused. This way you can transfer the tokens to a new device if you need to transfer them.

Duo Mobile. I'm sorry at vikoristanni and allowances for additional adjustments. The same with Google Authenticator has one advantage: Duo Mobile requires a code to enter the code, which requires pressing on a specific token. If you feel discomfort immediately when you open the authenticator and show everyone a bunch of codes from all your cloud accounts, then you will like this feature of Duo Mobile.

There are a number of reasons why you may be eligible for this authenticator, which is part of Red Hat. First of all, it is your choice if you like open source software. In other words, the least significant addition from all those considered is that the iOS version takes up only 750 KB. For comparison: the minimalist Google Authenticator takes up at least 14 MB, and the Authy add-on, which we’ll talk about below, takes up as much as 44 MB.

Thirdly, after the search, the program shows the codes and shows them only after the torment. Finally, fourthly, FreeOTP allows you to configure tokens manually as much as possible, as needed. Apparently, the primary method of creating a token by scanning a QR code is also supported.

Authy. In addition to the additions for two-factor authentication, the main advantage is that all tokens are stored in the dark. This allows you to deny access to a token from any of your devices. At the same time, it will make it easier to move to a new device - you won’t have to re-activate 2FA in each service, you can continue to use existing tokens. If your device is on IOS, then you need to animate it. To link programs you need to press “+”. Scan the QR code or enter the key that will give you the site. Let's take a look at the crypto exchange 50x.

On the site, we go to the 2FA settings and press to enable two-factor authentication. We are given a QR code and a key.

It is absolutely necessary to write down this key somewhere on a paper - this will help you regain access in case of a breakdown or loss of the phone. We will also not hesitate to take a photo or screenshot of the QR code and grab it from a reliable place.

In the mobile app “Authenticator” press “+” and select “Scan barcode”. Point the camera at the QR code. This way you will add Authenticator to the exchange 50x. If the camera does not work, you need to scan, select “manually entered” and enter the Authenticator key. In a similar way, cloud records of other resources can be added.

Video on how to install Google Authenticator on Windows

If you do not have a phone running Android or iOS, you can install the program on Windows. How to start marveling with video instructions:

Where do I get the 2FA code?

If the site asks you to enter a 2FA code, you will need to launch the program and you will enter a six-digit code. This code changes every 30 seconds. If the code turns blue, it means that the hour of your activity has ended, so you better check a new one and quickly enter it.

How to update your account

This situation could happen if the phone got damaged, lost, or God forbid it was stolen. What should you do? How to renew access to google authenticator?

The right thing is that the program does not communicate with Google servers and does not transmit anything there. Authenticator does not interfere with backup. All information is available on your smartphone. There are only two options for updating access.

1. If you, when adding a cloud account, wrote down the key or took a screenshot of the QR code, then it is not important to renew access. You simply download the program to your new phone and add an account record, a password key or a QR code.
2. If you didn’t save the codes and didn’t save the codes, the cloud records were lost again. In such a situation, it will be helpful to support the project. Only you can delete the old 2FA, and you can also create a new one.

Two-step authentication in Google

Your Google account will require strong security, so you will need to login to access your bank card details to make purchases from the Google Play app store, important updates, documents and sheets, and watch videos on YouTube. Fortunately, the technology giant implemented a two-factor authentication system back in 2010.

Google calls this system “Double-Step Authentication.” This method allows you to identify the user of a mobile device. When two-step verification is enabled in Google, several options are available. The first option is called Google Prompt - the user simply adds his smartphone to the cloud account and verifies that the Google search program is installed on the device. Then, when you try to enter the cloud account, you will need to confirm on your smartphone what you are doing specifically.

If you don’t ask, you will have to enter an additional code that will be sent to your smartphone via SMS text notification, voice call, or Google Authenticator. You can register your computer with your personal cloud account so that you do not have to enter a code for personal authorization. If you are the owner of a corporate G Suite account, you can set up a code withdrawal for 30 days.

Google Authenticator can generate an authentication code if your smartphone is not connected to the Internet. You will need to enable two-step authentication first. Then the program will scan the QR code on the desktop screen, and then generate a one-time password according to the hour or value of the doctor, which will need to be entered in the corresponding field. This method replaces text notifications, voice calls or email notifications. Google Authenticator supports work with other services, such as LastPass, Facebook, Evernote, Microsoft, Dropbox and Slack.

After setting up Google's two-step authentication, go back to the Google Cloud account setup section. You can set up the phone number for which you will need access codes, go to Google Authenticator and deny access to up to 10 backup codes, which can be separated due to emergency situations (for example, the smartphone battery is low and you cannot deny access to programs for authentication).

In which interface you can delete accessory passwords. Let's assume that you want to hijack a Google account record for a service that does not support Google's standard authorization. If you have two-factor authentication enabled, you will need a program password to access Google's account account with the service.

How to use two-factor authentication on Google

1. Click on the profile page at the top right corner of the screen and click on the “My account” button.
2. Once you have accessed the account account page, select the “Security and Login” page.
3. In the “Password and login method to cloud account” section, select the “Double-step authentication” item.
4. At this point, if you want to change the authentication procedure, Google may ask you to re-enter your password. Enter your password to continue security setup.
5. Now you can set up two-step authentication. Click the “Proceed” button.
6. Enter your phone number. You can receive text notifications or phone calls to this number. Select the appropriate option and click “Next”.
7. After this you receive an SMS notification or a phone call with an access code. Just enter the numbers without the prefix “-G” and press “Distances”.
8. After this, the notification page “It’s out!” will open! Enable two-step authentication? Press "Squeeze".

After this, you can go to the page for setting up two-step authentication, where you can set up an alternative factor because you can’t cancel text notifications or voice calls. Please note that vikorysts have an option to remove SMS codes. The usefulness of this method lies with your steel operator. In addition, this method is less secure than other methods available. Another popular option is using Google Authenticator or Google Prompt. They also require the presence of a mobile device.

How to add Google Authenticator as another authentication factor

1. Install the Google Authenticator program on your mobile device
2. Go to the page for setting up two-step authentication for your Google account and click the “Create” button in the “Authenticator Add-on” panel.
3. Select the operating system of your smartphone - Android or iOS and press "Next"
4. Open the Google Authenticator program on your mobile device and select the “Scan barcode” option
5. Scan the QR code that appears on your computer screen and click Next
6. A notification “Secret code saved” and a digital code will appear on the screen of your mobile phone. Enter the code on your computer and click “Confirm”

How to add Google Prompt as another authentication factor

1. Go to the page for setting up two-step authentication for your Google account and click the “Add phone” button in the “Google Prompt” panel.
2. On the next screen, press “Start”
3. Then select your phone and link it to your Google account. Make sure you have the Google search app installed on your phone and are not connected to the Internet. Press "Distance".
4. On the notification on your mobile phone, press the “So” button.
5. Then press the “Done” button on your computer. Setting up Google Prompt is complete.

How to create a password using Google programs

The program password is a 16-digit access code that allows programs or devices to access a Google account. If you use two-step authentication and use the “wrong password” error when you try to access your Google account, the program password may cause the problem. In most situations, you will need to enter the program password only once for each program or device, so don’t worry about remembering it.

1. Click on the “Passwords for add-ons” section in the “Password and login method” section of the Google account security setup page. You may be asked to sign in to your Google account.
2. At the bottom of the list that appears, select the program you are using.
3. From the following list, select the device you are using.
4. Click the "Create" button.
5. Enter your account to enter the program password (16-digit code in the first row) on the device.
6. Click "Done".

Passwords do not break unless they are lazy. The recent massive influx of cloud records from Yahoo further confirms the fact that the loss of a password alone - and no matter what complexity it takes - is no longer enough for reliable protection. Two-factor authentication is something that provides such protection, adding additional security.

Theoretically, everything looks bad, but in practical terms, it all works. Two-factor authentication truly thwarts the evils of cloud recording. Now the evildoer doesn’t have enough vimanity, steal the main password. To enter before the account, you need to enter another one-time code, which... And the only way to enter this one-time code is the same.

Having tried two-factor authentication more than once, you probably haven’t heard of it at all. If you entered a one-time code, what kind of force did you get via SMS? That's right, here's a new version of two-factor authentication. Does it help? Although they seem great, they are not: the evil-doers have already begun to suppress this kind of destruction.

Today we will look at all types of two-factor authentication that are used to protect Google Account, Apple ID and Microsoft Account accounts on the Android, iOS and Windows 10 Mobile platforms.

Apple

Two-factor authentication first appeared in Apple devices in 2013. At that time, it was not easy to transfer the koristuvachs due to the need for additional protection. Apple did not begin to make money: two-factor authentication (which is called two-step verification, or Two-Step Verification) was developed only to protect against direct financial harm. For example, a one-time code will be required when purchasing a new device, changing a password, and to subscribe to the support service on those associated with the Apple ID cloud account.

Things didn't end well. In 2014, there was a massive wave of celebrity photographs. Hackers managed to deny access to the victims’ cloud records and stole photos from iCloud. As a result of the scandal, Apple quickly expanded its two-step verification for access to backups and photos in iCloud. At this time, the company continued to use robots using the new generation of two-factor authentication method.

Two-step verification

To deliver codes, a two-step verification is carried out using the Find My Phone mechanism, which provides a set of purposes for delivering push notifications and blocking commands when the phone is lost or stolen. The code is displayed on top of the lock screen, apparently, if the attacker has removed the device’s trust, you can remove the one-time code and use it quickly, even if you don’t know the password for the device. This delivery mechanism is a weak point.

The same code can be retrieved from the SMS view or from the voice call to the registered phone number. This method of anitroxia is not safe. The SIM card can be removed from a stolen iPhone and inserted into any other device, after which the code is accepted. Yes, the SIM card can be cloned or taken from a mobile operator for a separate license - this type of cheating has suddenly become epidemic in nature.

If you do not have access to a trusted iPhone, nor to a trusted phone number, then to access the cloud account you will need to use a special 14-digit key (which, before speaking, is recommended to be separated and saved in a safe place, and in When traveling - take it with you ). If you spend everything, you won’t get much back: access to the account may be closed forever.

How safe is it?

I'm honestly not much better. The two-step verification was implemented in a very bad way and deservedly damaged the reputation of the worst two-factor authentication system among all the leaders of the “Great Three”. Since there is no other choice, then a two-stage verification is still better, nothing less. Let's face it: with the release of iOS 9, Apple introduced a completely new security system, simply called “two-factor authentication.”

What is the weakness of this system? First, one-time codes delivered through the Find My Phone mechanism are displayed directly on the lock screen. Otherwise, authentication based on phone numbers is not secure: SMS can be transferred either by the provider or by replacing or cloning the SIM card. Since there is physical access to the SIM card, it can simply be installed in another device and the code can be retrieved from all legitimate platforms.

It’s also a good thing in May that the criminals have begun to steal SIM cards instead of “spent” for additional powers of attorney. If your password has been stolen, then finding out your phone number is useless. The trust is renewed, getting a new SIM card is all done, nothing else is required to access your account account.

How to fix Apple authentication

It’s easy to use this option for two-factor authentication. There are a number of options:

• obtain a one-time code from a trusted device - unblocking is not obligatory;
• move the SIM card to another device, cancel the SMS;
• clone the SIM card, remove the code from it;
• Quickly use a binary authentication token copied from the customer’s computer.

How to get carried away

The request for additional two-step verification is not serious. Not vikorystovaya її взagali. Instead, use proper two-factor authentication.

Two-factor authentication

Another Apple attempt is officially called “two-factor authentication.” Instead, in order to change the previous two-stage verification scheme, the two systems begin in parallel (however, within the same cloud record, only one of the two schemes can be verified).

Two-factor authentication appeared as a part of iOS 9 and the version of macOS that was released immediately after it. The new method of turning on to Poddatkova, when I am a click, go to the Opple ID NEW WHAT: IPHONE, IPAD, IPAD, IPAD TOUCH TOMENTERS P'yuri PID Keruvannya MacOS) instantly monitor the IINTERSIAL MANYECTIVE. To revoke access before notification, you need to unlock the device (with a password or fingerprint sensor), and to unlock the one-time code, you need to press the confirm button in the dialog box.

Like the previous method, the new scheme allows you to recover a one-time password like an SMS or a voice call to a trusted phone number. However, as a result of the two-step verification, a push notification will be delivered to the customer at any time, and an unauthorized attempt to enter the cloud account may be blocked by the customer from their devices.

Accessory passwords are required. And the code for renewing access to Apple has been updated: if you use your only iPhone with a trusted SIM card (for some reason you can’t confirm), to renew access to the cloud recording, you will have to go through the following procedure quest from confirmed individuals (no, A scan of a passport does not support such confirmations... the same original, as it seems, “doesn’t matter”).

In fact, the new system has finally found a place for manual and offline schemes for generating one-time codes. It uses the standard TOTP (time-based one-time password) mechanism, which generates one-time codes every thirty seconds that consist of six digits. These codes are linked to the exact hour, and the role of the generator (authenticator) is played by the device itself. The code can be obtained from above the system settings of the iPhone or iPad via Apple ID -> Password and Security.

We will not clearly explain what TOTP is and what it means, except for the main features of implementing this method in iOS, as well as similar schemes in Android and Windows.

In contrast to its main competitors, Apple allows users to use authenticators as authenticators, including power generation devices. Their role can be played by a trusted iPhone, iPad or iPod Touch running iOS 9 or 10. In this case, the device is initiated with a unique secret, which allows you to easily and painlessly contact a new (and only from new) trust status. If the Google authenticator is compromised, then click on (and reinitialize) the status of all initialized authenticators, the results in Google have determined that there is a single secret for cialization.

How safe it is

Although it has been implemented in advance, the new scheme is still more secure. Having always been supported by the operating system, the new scheme is more consistent, logical and straightforward in the vicoristan, which is important from the point of view of earning money from investors. The one-time password delivery system has also been completely redesigned; The only weak point that has been lost is delivery to a trusted telephone number, which merchant, as before, is responsible for verification in the obligatory order.

Now, when you try to log in before the cloud recording, the server will receive push notifications for all the device’s permissions, which may prevent the test. If you want to complete your Swedish activities, you may be able to deny access to the cloud record.

How to solve two-factor authentication

As in the first scheme, two-factor authentication can be achieved using an additional authentication token copied from the customer’s computer. An attack on the SIM card can also occur, but if you try to recover the code via SMS, you will still be notified on all trusted devices of the customer, and you may be able to log in. And you will no longer be able to look at the code on the screen of a locked device: you will have to unlock the device and confirm the dialogue window.

How to get carried away

The new system doesn't have a lot of hazards. If Apple was convinced that it was mandatory to add a trusted phone number (and to activate two-factor authentication, it wanted one phone number to be verified in a mandatory manner), it could be called ideal. Unfortunately, the need to verify a phone number causes serious problems. You can try to steal the same way as you steal the number to which you receive one-time passwords for the bank.

The standard procedure for identifying a client on the Internet or in any system will require the client's name and password. And although you want to use shorter passwords, there is no need for security, such as this - they do not provide sufficient hope for security.

If, for example, you can easily retrieve data from a cloud record, it is not important for anyone to steal value and important information for people. To prevent unauthorized access to your system and data, use two-factor authentication (2FA).

What is two-factor authentication?

Two-factor authentication(for some devices it is possible to comply - two-step verification or two-step verification) is an additional measure of protection for the authentication of a customer. If a customer enters data for their account account in order to access the site, in addition to the login and password, they will need to provide another one factor for authentication.

Authentication officer- any information, parameter or characteristic that only the owner of the cloud record or is entrusted to the person and may:

• knowledge factor – those that the customer knows (PIN code, password, code word, confirmation of confidentiality, etc.);
• Volodinnya factor – those with which Volodinya is valuable (key, passport, smart card, security token, USB flash drive, disk, smartphone and other mobile device);
• - those that are partly koristuvach (fingertips, iris and retina, voice, facial geometry). This also includes behavioral biometrics, such as the dynamics of key pressure, strokes or physical patterns;
• growth factor - (for example, behind an IP address or through a satellite navigation system);
• hour factor - a specific hour interval is recorded, by which time you can reach the system.

At the same time, due to the fact that the password will not be protected by the necessary security measures, two-factor security (2FA) will be installed everywhere. This technology is found in social networks, forums, blogs, instant messengers, games, online banking, etc. A two-step verification will involve Apple, Facebook, Twitter, VKontakte, Gmail, Yandex, Google, Microsoft and many other market leaders. Here this method is considered as an additional security factor, and here as one of the obligatory ones.

Thus, since knowing the password is no longer sufficient for authentication, two-factor authentication significantly complicates the task for a potential attacker and acts as a driving factor, and in some cases a stopping factor.

What are the types of two-factor authentication?

More than anything, you have repeatedly encountered a two-step verification process, for example, if you tried to access a social media account from another computer or phone, and at that moment, the service, suspicious of suspicious activity, asked you to short code, which is the address of the telephone. This is just one form of 2FA submission, but in general it is more rich and can be implemented as:

• Having a password + availability of a special PIN code via SMS notification, email or mobile app - this option is the easiest to implement and the most popular among others;
• Username and password + photo - this means that when you try to log in, a photo will be taken using an additional webcam and sent to a trusted device (mobile phone, tablet, laptop). All that is lost is to confirm on another device the validity of the captured photo or to deviate, thereby blocking access for the attacker;
• Your password + visual tag - if you have a webcam on your computer every day and don’t like to take photos, you can go through two-factor authentication in a different way. Visual tag - forms a unique visual code, which is calculated using a special algorithm and is displayed to the user on two devices at the same time, allowing authentication using the code authentication method;
• I have a password + biometrics (finger type, hand geometry, retina or iris, face, voice) - if access to the system is denied, the connection will be transferred to a specific device, regardless of the user’s consumption Please enter the required biometric parameter;
• Im'ya Koristuvach that password + Apalliy-bastard (USB-hobby, smart card, token, key)-for the passage of the double-acting Authentiface, put the key to access, to put the card to the special Zchituvach, and the synchronizuvati, for the synchronizuvati, forces, on the token, on the toe, on the right-handed, for the right. via Bluetooth;
• Customer name and password + metadata - customer authentication only applies to all necessary parameters. Zokrema is in need of assistance from GPS. The pilot, who uses GPS equipment, often sends the coordinates of the satellites that are in the line of sight. An authentication subsystem that knows the orbits of satellites, with an accuracy of up to a meter. You can also change the hour, for example, you can log in to the system from 8:00 to 9:00, at other times access is blocked. As an alternative, there is a permanent link to the operating system and components of the device, so that the IP addresses of the devices (operating system, programs, etc.) are recorded.

Hacker attacks are most often carried out via the Internet, so two-step verification makes such attacks less risky. However, since the attacker captures data from a cloud account, it is unlikely that they will be able to remove another authentication factor.

Setting up two-step authentication

There are many applications of these sites and resources, and another factor is not just an attribute in settings, but a key element that can ultimately influence the security of cloud recording.

This is what the setup of two-factor authentication looks like for a social network VKontakte:

Allows you to ensure reliable protection against malicious cloud records: to enter the site you need to enter a one-time code, an SMS code or another way available for connection.

Improves the security of cloud recording and when entering the skin from the new device, an identifier code is applied.

Google As one of these lighting companies simply cannot do without this function, it allows you to connect another factor for authentication in settings:

As soon as you sign in to your Google account, you will be required to enter a password and a one-time verification code.

The competitor of the former - in its arsenal also has the following functionality:

In this case, when logging into your Yandex account, you do not need to enter a password - you will need to enter the verification code from the SMS notification.

For koristuvachs " apple devices» This is how apple two-factor authentication works, which you can connect on both your phone and your computer:

If 2FA is disabled, you may be unable to revoke access to your account account in Apple ID if you enter a special verification combination with SMS notification or through device trusts.

Infection with any important company or organization that operates on the Internet, where it is possible to register an account record - there is a two-factor authentication function . Here the direction on the right is not for the person, but for those who are safe in the current world. The password and PIN code are likely to be selected within a very short period of time, since another factor is not always possible for the attacker. The very presence of this function can be demonstrated practically on any service or website (where there are accounts of clients).

Where can I enable two-factor authentication?

Here the power supply, most likely, needs to be placed differently - and what needs to be connected? Because it is possible to connect practically directly, but what is the point? Here it is necessary to respect the fact how important this resource is for you and how information should not be misplaced. As this is such a forum, de Vi was only once and they didn’t provide the same data – it’s not good to get excited. For example, social security, electronic mail and a special account in an online bank are definitely necessary and in this case there is no reason for everyday doubts. The main resources where you can enable dual-step authentication:

How to enable two-factor authentication (2FA)?

When choosing a different authentication method for your site, you must first consider the necessary level of security and reliability. Because Since life will never be simpler in all aspects, two-factor authentication is often seen as a powerful barrier that allows you to filter out unnecessary information quickly and without any further action. However, this does not mean that you do not have the security of cloud recording.

As in the first section - to increase respect for the public record and the value of information, which is located in the new. If the theft of such a record does not lead to incorrect inheritances, and if another factor creates additional difficulties, it is difficult to include it. Otherwise, don’t bother anyone, but rather tell them how you can improve the level of protection and security.

How to perform two-step verification?

Varto understand that two factors are the main solution to protection, but they are not a panacea. There are a number of methods that allow you to get around everything:

• the way of stealing a mobile device or another factor for access;
• for further assistance, duplicating a SIM card;
• for the help of cheap software features, which will prevent you from asking for an SMS notification from a customer service provider.

The advantage of two-factor authentication

• By following the phrase “One head is good, but two are better”, you can create a solution so that one password or PIN code is good, but if there are two of them, with such a different nature, the security of the cloud record, the device and the system will be much more reliable ;
• in case of theft, or theft of a login and - You will find out about it through the program or SMS notification, which allows you to respond and update the compromised password in the cloud account;
• generation of new unique code combinations when logging into the system, so the password becomes permanent (until you change it yourself).

Few parts of two-factor authentication

• If the authentication factor is set up via a mobile device via SMS notification, then if the signal is lost, you will not be able to log into your account;
• If anyone really needs it - the reliability of cloning a SIM card and the transfer of information to your mobile phone service provider;
• Your mobile device may run out of charge at the most unexpected moment.

Visnovok

Today, two-factor authentication is trusted by a lot of large companies, including organizations in the IT sector, the financial sector, the market, and previous government institutions. Over time, 2FA will be affected by a complex security element, because with the development of technology, hacker tricks for stealing information and data are also being developed. However, it is possible to quickly meet two security factors - to earn the same.
