However, the two-factor protection isn’t a cure-all solution for account theft, but it’s quite a reliable barrier that seriously complicates access to the data of others and to some extent eliminates the disadvantages of classic password protection. In general, the essence of the approach is very simple: in order to get somewhere, you need to confirm twice that you’re you, using two “keys”, one of which you possess and one of which you keep in your memory. Less frequently the second “layer” of protection asks for a special USB key or user’s biometric data.
In practice, it usually looks like this: the first layer is a username and password, and the second is a special code that comes via SMS or email. Two-factor authentication is a method of user identification in any service (usually on the Internet) by requesting authentication data of two different types, which provides two-layer and, therefore, more effective protection of the account against unauthorized intrusion.
