    What is a multi-factor authentication? 23.2.2

    • A.

      A. A type of authentication that involves solving math problems.

    • B.

      B. Authentication that requires multiple types of input.

    • C.

      C. A password that has alphabetical and numerical characters.

    Correct Answer
    B. B. Authentication that requires multiple types of input.
    Explanation
    Multi-factor authentication is a type of authentication that requires multiple types of input. This means that in order to gain access to a system or account, the user must provide more than just a password. It typically involves a combination of something the user knows (such as a password), something the user has (such as a security token or smartphone), and something the user is (such as a fingerprint or facial recognition). This added layer of security helps to protect against unauthorized access and enhances the overall security of the system or account.
