A classification of identity-verification methods in information security, divided into three types: possession factors (something you have, such as an IC card), biometric factors (something you are, such as a fingerprint or face), and knowledge factors (something you know, such as a password). Multi-factor authentication, which combines two or more of these, provides significantly stronger security than single-factor approaches.
