Multi Factor Authentication (MFA)

an electronic authentication method in which a computer 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. The factors can be:

  • Knowledge – something the user and only the user knows
  • Possession – something the user and only the user has, and
  • Inherence – something the user and only the user is – such as their biometric

MFA protects the user and the system they are trying to access from an unknown person trying to access the system and the system’sdata such as personal ID details or financial assets.
