CSPs that create look-up secret authenticators SHALL use an approved random bit generator, as described in Sec. 3.2.12 , to generate the list of secrets and SHALL deliver the authenticator list securely to the subscriber (e.g., in an in-person session, via an online session, through the postal mail to a contact address). If delivered via an online session, the session SHALL be authenticated by the subscriber at AAL2 or higher and SHALL deliver the secrets through an authenticated protected channel and in accordance with the post-enrollment binding requirements in Sec. 4.1.2 . Look-up secrets SHALL be at least six decimal digits (or equivalent) in length. Additional requirements described in Sec. 3.1.2.2 may also apply, depending on their length.
