A mobile device user is concerned about security. The user wants to use multifactor authentication on the device. Which of the following would BEST accomplish this?

Question

Options

• APasscode lock and swipe lock
• BFingerprint lock and passcode lock
• CPicture passcode and pin lock
• DFace lock and fingerprint lock

• A
  6% (3)
• B
  89% (42)
• C
  2% (1)
• D
  2% (1)

Explanation

Multifactor authentication (MFA) requires two or more different types of authentication factors: something you know, something you have, or something you are. Fingerprint lock (biometric = something you are) combined with passcode lock (something you know) satisfies MFA because they represent two distinct factor categories. Options A and C both use two 'something you know' factors (swipe/passcode, picture/PIN), which is single-factor authentication used twice-not true MFA. Option D (face lock + fingerprint) uses two biometric factors from the same category, also not true MFA.
