What Is Multi-Factor Authentication (MFA)?
Multi-factor Authentication (MFA) is a security process that requires you to verify your identity in more than one way when signing into an account. It is designed to strengthen the account by adding additional layers of protection beyond just a username and password.
MFA uses at least two of the following three categories to confirm your identity:
- Something you know (such as a password)
- Something you have (such as a mobile device, hardware token, or security key)
- Something you are (such as facial recognition or fingerprint)
This layered approach greatly reduces the likelihood of unauthorized access and helps keep your account secure.
