in an interview, you are asked to compare the following statements regarding different authentication concepts and identify the correct statement. which of the following statements is correct?
a hmac - based one - time password (hotp) changes after a set period of time.
physiological biometrics is relating to the way in which the mind functions.
a persons vein can be used to uniquely authenticate an individual.
a windowed token displays a static code.

Explanation:

For the first question, a password key is a hardware - based solution as it is a physical device. A password vault is software - based, password digest and salts are cryptographic concepts related to password storage.
For the second question, a HMAC - based one - time password (HOTP) is event - based not time - based, physiological biometrics relate to the body not the mind, and a windowed token displays a dynamic code. Veins can be used for biometric authentication as they are unique to an individual.

Answer:

First question: Password key
Second question: A person's vein can be used to uniquely authenticate an individual.
