For each of the given items, select the appropriate authentication category from the drop down choices.
Select the appropriate authentication type for the following items:
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 HMAC-based 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.
