Multifactor Authentication

Definition

Multifactor authentication is a security measure that requires users to provide two or more different types of identification in order to access a system or application. It adds an extra layer of protection by combining something the user knows (like a password) with something they have (like a fingerprint) or something they are (like facial recognition).
