Which of the following is an example of two-factor authentication?
Answer and explanation
Correct answer: Entering a password along with an OTP received on a mobile phone
Two-factor authentication uses two different categories of evidence, commonly something the user knows, such as a password, and something the user possesses, such as a registered phone receiving an OTP. A username is normally an identifier, not an authentication factor by itself. A password alone or a fingerprint alone uses only one factor, so option B is the correct example.
