comptia sy0-501 exam questions q9-2

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.
Two types of tokens exist, Time-based one-time password (TOTP) tokens and HMACbased one-time 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 hash or HMAC operation.
Smart cards can have Multi-factor and proximity authentication embedded into it.
PAP allows for two entities to share a password in advance and use the password as the basis of authentication. The
same goes for PIN numbers.
