Two-factor authentication is when two different authentication factors are provided for authentication purposes.
Speaking (Voice) – something they are.
Passphrase – something they know.

Incorrect Answers:
B: Identification is the act of claiming an identity using a single authentication factor, and authorization controls what a subject can and can’t do, access, use, or view.
C: Single sign-on (SSO) is to give users access to all the applications and systems they need when they log on.
D: Single factor authentication only requires one authentication factor for authentication purposes.
