Which of the following is true of two-factor authentication?
A. It requires two measurements of hand geometry.
B. It relies on two independent proofs of identity.
C. It does not use single sign-on technology.
D. It uses the RSA public-key signature based on integers with large prime factors.
Answer:B
Which of the following is true of two-factor authentication?
A. It requires two measurements of hand geometry. B. It relies on two independent proofs of identity. C. It does not use single sign-on technology. D. It uses the RSA public-key signature based on integers with large prime factors.
Explanation: It relies on two independent proofs of identity. Two-factor authentication refers to using two independent proofs of identity, such as something the user has (e.g. a token card) and something the user knows (a password). Two-factor authentication may be used with single sign-on.
