2FA stands for "two-factor authentication", which is a security process that needs a customer to provide two different forms of identification before accessing their account or service. The goal of 2FA is to increase the security of online accounts by adding an extra layer of protection beyond just a username and password.The two-factors typically used in 2FA are:
- Something the user knows, such as a password or PIN.
- Something the user has, such as a mobile device or security token.
When a user tries to log in to an account with 2FA enabled, they will be prompted to enter their username and password as usual. They will then be asked to provide a additional piece of identification, such as a code generated by a mobile app or sent via SMS to their phone. This means that Even if someone manages to steal your password, they would also need access to your phone or another second factor to gain access to your account.
