Knowledge Factors The username or e-mail address on its own is not considered an authentication factor - this is how the user claims their identity to the system. A password or PIN number is used to authenticate that the username or e-mail address is being provided by the correct person.
Four-factor authentication (4FA) is the use of four types of identity-confirming credentials, typically categorized as knowledge, possession, inherence and location factors.

There are three authentication factors that can be used: something you know, something you have, and something you are. Something you know would be a password, a PIN, or some other personal information.
threeThere are three common factors used for authentication: Something you know (such as a password) Something you have (such as a smart card) Something you are (such as a fingerprint or other biometric method)Jun 6, 2011
Authentication using two or more different factors to achieve authentication. Factors include: (i) something you know (e.g., password/PIN); (ii) something you have (e.g., cryptographic identification device, token); or (iii) something you are (e.g., biometric).
There are various ways to protect accounts via two-factor authentication: biometrics, one-time passwords, verification codes, QR codes, hardware tokens, and other methods all add another layer of security.
With 2-Step Verification (also known as two-factor authentication), you add an extra layer of security to your account in case your password is stolen. After you set up 2-Step Verification, you'll sign in to your account in two steps using: Something you know, like your password. Something you have, like your phone.
How Many Types of Authentication Are There? There are three basic types of authentication that we typically consider. The first is knowledge-based — you know something like a password or PIN code that only you, the identified user, would know.
The difference between MFA and 2FA is simple. Two-factor authentication (2FA) always utilizes two of these factors to verify the user's identity. Multi-factor authentication (MFA) could involve two of the factors or it could involve all three. “Multi-factor” just means any number of factors greater than one.Dec 29, 2020
