Multi-factor authentication
Method of computer access control / From Wikipedia, the free encyclopedia
"Two-factor authentication" redirects here. For two-factor authentication on Wikipedia, see Help:Two-factor authentication.
Multi-factor authentication (MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism. MFA protects personal data—which may include personal identification or financial assets—from being accessed by an unauthorized third party that may have been able to discover, for example, a single password.

Usage of MFA has increased in recent years, however, there are numerous threats that consistently makes it hard to ensure MFA is entirely secure.[1]
