AAA authentication, also known as triple A authentication, is an online system of verifying a user’s identity by using three pieces of information: something the user knows (like a password or PIN), something the user has (like a physical token or a text message on their phone), and something the user is (like biometric authentication such as fingerprint scans). AAA authentication is seen as one of the most secure methods of verifying a user’s identity, since it requires multiple layers of authentication.
