Explanation
Authentication factors fall into three categories: something you know, something you have, and something you are. In this scenario: a username is an identifier (not an authentication factor), a PIN is 'something you know' (knowledge factor), a token is 'something you have' (possession factor), and a retina scan is 'something you are' (inherence/biometric factor). That gives three distinct authentication factors, making this a three-factor authentication system despite four inputs being collected.
