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.

Multi-factor authentication (MFA; two-factor authentication, or 2FA, along with similar terms) is an electronic authentication method in which a user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism.
Strong authentication is often confused with two-factor authentication (more generally known as multi-factor authentication), but strong authentication is not necessarily multi-factor authentication. Soliciting multiple answers to challenge questions may be considered strong authentication but, unless the process also retrieves "something you ...
Go to Special:Manage Two-factor authentication. Click "Enable", and log in with your username and password. Click the + button at the top-left of Authenticator. Add the secret 2FA key to Authenticator using either one of these methods: Use Authenticator to take a screenshot of the QR code: Click the QR code button at the top-right of Authenticator.
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.

Universal 2nd Factor (U2F) is an open standard that strengthens and simplifies two-factor authentication (2FA) using specialized Universal Serial Bus (USB), near-field communication (NFC), or Bluetooth Low Energy (BLE) devices based on similar security technology found in smart cards.
In any case, the authenticator is a multi-factor cryptographic authenticator that uses public-key cryptography to sign an authentication assertion targeted at the WebAuthn Relying Party. Assuming the authenticator uses a PIN for user verification, the authenticator itself is something you have while the PIN is something you know .
