Questions tagged [multi-factor-auth]
Often just MFA, a security measure that requires a user to provide multiple pieces of evidence of identity (factors) such as: knowledge (something the user knows); possession (something the user has) and inherence (something the user is). Use this tag for 2FA (two factor authentication) as well as when more than two factors are involved.
