Not everyone knows what two-factor authentication. In recent times users face hacking of accounts, and among them may be the Google account where we like to store the passwords of all the resources. How to protect yourself? Comes to the aid of two-factor authentication (2FA), it is currently the most reliable means of protection accounts.
Many services support 2FA, so the problems with its activation should not be. 2FA is two layers of protection. Typically, the first level is always a username and password, and already as a second barrier there may be different remedies. This can be a one-time password received on e-mail or SMS at the entrance, it could be the PIN that you already inform the service. There is also the possibility to log on with a fingerprint scanner or a face scanner, which is 2FA.
Google is a one-time password can send the token to the Authentificator app on your smartphone. Apple, for example, when entering the password, iCloud sends it to other smartphones with the same account location from where the login and one-time password that must be entered on the device from which the authorization occurs.
Many do not even think, but, for example, when you use your Bank card and its PIN-code is also an example of 2FA: the key card and PIN additional barrier that protects funds on the card. Telegram previously sent one-time code when you authorize a new device, and now the company sends the code not the SMS and messages to other devices with installed Telegram, which is also quite convenient.
