To use it, you must first install one of these applications (for example, and then select the two-factor authentication option in the menu of the desired service through the application. A QR code will appear on the screen, you need to scan it through this application and you can use it immediately. Many services (for example) also generate some backup codes for the user that connection or loses his phone.
To do this, you will need to print out these codes ahead of time or keep them moible number data in a safe place. In addition, there are several less commonly used types of login confirmations: Physical security key: This device takes the form of a flash drive (used in smartphones, which sometimes come with a Bluetooth interface). Such a key can be used to enter the same social network, but this no-nonsense approach makes more sense for storing very important data. Authentication using biometrics.
This approach is not yet used in a wide range of services such as social networking. Is two-factor authentication guaranteed to be absolutely secure? Kaspersky Lab senior cybersecurity expert said: Ideally, the second login factor should be present on a device other than the device on which the user logs into the account. The risk arises when using the same device to log into an account and receive a one-time password. If an attacker is able to infect this device with some type of Trojan horse, then one-time passwords will no longer be considered secure.
