Check Contents

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 Management tool, verify the "Passcode History" value is set to two 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 Apple iOS/iPadOS management tool containing the password policy.
5. Tap "Restrictions".
6. Tap "Passcode".
7. Verify "Number of unique recent passcodes required" is listed as "two" or greater.

If the Apple iOS or iPadOS device does not enforce a passcode reuse prohibition of at least two generations, this is a finding.
