Passwords can be cracked. Two-factor authentication is one way to avoid this. Its use implies that users will have to confirm their identity using a code that will be sent to a mobile phone or any other device.

Therefore, even if the password was stolen, the hacker will not be able to access your site without a special code. It can be sent to the phone number specified during registration, email, to the application, etc.

Methods for obtaining the Two-factor code used for verification
