A user attempting to log on to a workstation for the first time is prompted for the following
information before being granted access: username, password, and a four-digit security pin that
was mailed to him during account registration. This is an example of which of the following?
A.
Dual-factor authentication
B.
Multifactor authentication
C.
Single factor authentication
D.
Biometric authentication
Username & password along with PIN is two-factor authentication.
user name, password, and PIN are single factor authentication because its in the something you know category.
“and a four-digit security pin that was mailed to him during account registration”
Doesn’t the email counts as something the user HAS.
So it should be dual-factor authentication because its something he knows (password, username, pin) and something he has (email).
