Two-Factor Authentication is a part of the broader family of multi-factor authentication, which is a defense in depth approach to security. Two-factor authentication has been used throughout history by having a known person utter a password. The first factor is the password, and the second would often be the presentation and demeanor of the requestor as reasonable given the circumstances of his arrival. The security of a system relies on the integrity of the authenticator and physical protection of the "something you have". Copy protection of the "something you have" is a bonus. This may comprise some form of physical tamper resistance or tamper-proofing, may use a challenge/response to prove knowledge of the shared secret to avoid disclosure, and may involve the use of a pin or password associated with the device itself, independent of any password that might have been demanded as a first factor. A challenge/response will not defeat a man-in-the-middle attack on the current authentication session but will prevent the attacker from successfully reusing or replaying credentials on his own. Two-factor authentication is based on something you know (a password or PIN) and something you have (an authenticator)—providing a much more reliable level of user authentication than reusable passwords.
