The requirements for a multi-factor cryptographic verifier are identical to those for a single-factor cryptographic verifier, as described in Sec. 3.1.6.2 . Some multi-factor authenticators include flags to indicate whether an activation factor was used. If such a flag is present and indicates that an activation factor was not used, the authentication SHALL be treated as single-factor. Otherwise, verification of the output from a multi- factor cryptographic authenticator indicates that the activation factor was used.
