Multi-factor Authentication (MFA) is an authentication method that requires the user to provide two or more verification factors to gain access to a resource such as an online application.
A factor in authentication is a way of confirming your identity when you try to sign in. For example, a password is one kind of factor, it's a thing you know. The three most common kinds of factors are:
- Something you know - Like a password, or a memorized PIN
- Something you have - Like a smartphone, or a secure USB key.
- Something you are - Like a fingerprint, or facial recognition.
