Multi-factor authentication (MFA) is a multi-step account login process that requires users to enter more information than just a password. For example, along with the password, users might be asked to enter a code sent to their SMS, email, answer a secret question or scan a fingerprint and authenticator apps. It gives an extra layer of security to your account.
