Annex A 5.17
Authentication information
Allocation and management of authentication information is controlled, including guidance to users.
What an assessor looks for
Show how credentials are issued, how they are transmitted to the user, and what happens on reset. Multi-factor coverage and its exceptions attract particular attention.
Where it usually fails
Multi-factor authentication is enforced for staff and quietly excluded for administrators, legacy protocols, or service accounts.
