Multi-factor authentication (MFA)

Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting several separate authentication stages through credentials based on knowledge (something you know), possession (something you have), and inherence (something you are), in other words, it is a system that requires more than one method of authentication from a self-reliant listing of credentials to verify a user's identity for login.
