Multi-factor authentication and providers

Multi-factor authentication (MFA) is a method of computer access control which a user can pass by successfully presenting authentication factors from at least two of the three categories:

  • knowledge factors ("things only the user knows"), such as passwords
  • possession factors ("things only the user has"), such as ATM cards
  • inherence factors ("things only the user is"), such as biometrics

Requiring more than one independent factor increases the difficulty of providing false credentials.
