What is an Multi-factor and Two-factor Authentication?

Multi-factor authentication (MFA) is an authentication method in which a computer user is granted access only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism.

Two-factor authentication (also known as 2FA) is a subset of multi-factor authentication. It is used to confirm users’ claimed identities by way of at least two different factors: e.g. 1) something they know, 2) something they have, or 3) something they are.
