An example of two-factor authentication is:
A.
An ID and a PIN.
B.
A PIN and an ATM card.
C.
A finger print.
D.
A password and an ID.
Explanation:
The correct answer is “APIN and an ATM card”. These items are something you know and something
you have. Answer “A password and an ID” is incorrect because essentially, only one factor is being
used: something you know (password.). Answer “An ID and a PIN” is incorrect for the same reason.
Answer “A finger print” is incorrect because only one biometric factor is being used.
