What are Multi-Factor and Two-Factor Authentication?
Last Updated a year ago

Multi-factor authentication (MFA) is an improvement over relying on a password to verify your identity. Multi-factor authentication requires successfully responding to several questions or prompts before permission is granted to access the service. The different factors include:
  1. Something you know (usernames, passwords, security questions)
  2. Something you have (a key fob, or a one-time code sent to a mobile device or email)
  3. Something you are (a fingerprint, face scan, etc.)
  4. Somewhere you are (geolocations)
  5. Something you do (keystroke patterns)
Two-factor authentication (2FA) is the simplest form of multi-factor authentication and requires passing just two of the above tests.

Some sites require that multiple questions be answered before access is granted. However, correctly answering two or more questions (like a password followed by the city in which you were born) is not as secure as two-factor authentication because both answers are things you know.
