Question

Quizplus · Accepted Answer

Two-factor authentication involves combining two different types of authentication methods. "Something the user is" refers to biometrics like a fingerprint, "something the user possesses" could be a physical token or key, and "something the user knows" could be a password or PIN. "Something the user calculates" is not typically a category used in authentication methods.
