Biometrics refers to a collection of physical attributes of the human body that can be used as identification or an
authentication factor. Fingerprints and retinas are physical attributes of the human body.

password (HOTP). TOTP tokens generate passwords at fixed time intervals, whereas HOTP tokens generate
passwords not based on fixed time intervals but instead based on a non-repeating one-way function, such as a
