DISA STIG recommends

AIOS-27-006500 CAT I

Apple iOS/iPadOS 27 must be configured to enforce a passcode reuse prohibition of at least two generations.

NIST SP 800-53: IA-5(1)

Check

Review configuration settings to confirm the Apple iOS or iPadOS device has a passcode reuse prohibition of at least two generations. This procedure is performed in the Apple iOS/iPadOS management tool and on the iPhone and iPad. Note: If an organization has multiple configuration profiles, the check procedure must be performed on the relevant configuration profiles applicable to the scope of the review. In the MDM server, verify in the Declarative Device Management (DDM) configuration "Passcodes" that the "Unique passcode requirement" value is set to "2" or greater. On the iPhone and iPad: 1. Open the Settings app. 2. Tap "General". 3. Tap "VPN & Device Management". 4. Tap the Configuration Profile from the MDM server containing the policy. 5. Tap "Configurations" and then "Passcode". 6. Verify "Unique passcode requirement" is listed as "2" or greater. If the MDM server or iOS or iPadOS device does not enforce a passcode reuse prohibition of at least two generations, this is a finding.

Fix

Install a DDM profile to enforce a passcode reuse prohibition of at least two generations (passcode history). In the MDM server, in the DDM configuration "Passcode", set "Unique passcode requirement" to "2" or greater.
