The document mentions biometrics fourteen separate times. The following year, the FFIEC released supplementary guidance that relaxed the strong authentication requirements, allowing institutions to add a "second authentication method" for layered security (not 2 factor authentication) – the supplement mentions biometrics only once. [11]
Soliciting multiple answers to challenge questions may be considered strong authentication but, unless the process also retrieves "something you have" or "something you are", it would not be considered multi-factor authentication. The FFIEC issued supplemental guidance on this subject in August 2006, in which they clarified, "By definition true ...

To establish TOTP authentication, the authenticatee and authenticator must pre-establish both the HOTP parameters and the following TOTP parameters: T 0, the Unix time from which to start counting time steps (default is 0), T X, an interval which will be used to calculate the value of the counter C T (default is 30 seconds).
Electronic authentication can reduce the risk of fraud and identity theft by verifying that a person is who they say they are when performing transactions online. [2] Various e-authentication methods can be used to authenticate a user's identify ranging from a password to higher levels of security that utilize multifactor authentication (MFA). [3]
Alice then has an authentication of Bob, and Bob has authentication of Alice. Taken together, they have mutual authentication. DIGEST-MD5 already enabled mutual authentication, but it was often incorrectly implemented. [2] [3] When Mallory runs a man-in-the-middle attack and forges a CA signature, she could retrieve a hash of the password.
