A method of authentication that requires one form of verification.

A method of authentication that requires one form of verification.

• A. Two-factor
• B. Single factor
• C. Multifactor
• D. Password only

Answer: (B)

Authentication often uses different kinds of evidence called factors. When only one form of verification is required, that’s single-factor authentication. It covers situations like using just a password (something you know) to gain access. Two-factor and multifactor require two or more factors, so they don’t fit the description. While a password alone is a common example of single-factor authentication, the general method name described by the prompt is single-factor authentication.
