Two-Factor authentication and MFA add an extra layer of security in the process of authenticating a user while signing in. Multi-factor authentication is a process of verification where the user needs to provide evidence from more than two of the above-mentioned categories to authenticate their identities before getting access to an application or a device. 2FA is different from 2SV (two-step verification) which may appear as same as 2FA at the first sight but the difference is loud and clear.
