Check Contents

Review configuration settings to confirm simple passcodes are not allowed.

This check procedure is performed on both the Apple iOS/iPadOS management tool and 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 Apple iOS/iPadOS management tool, verify "Allow simple value" is unchecked. Alternatively, verify the text "<key>allowSimple</key> <false/>" appears in the configuration profile (.mobileconfig file).

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 iOS management tool containing the password policy.
5. Tap "Restrictions".
6. Tap "Passcode".
7. Verify "Simple passcodes allowed" is set to "No".

If "Allow simple value" is checked in the Apple iOS/iPadOS management tool, "<key>allowSimple</key> <true/>" appears in the Configuration Profile, or the password policy on the iPhone and iPad does not have "Simple passcodes allowed" set to "No", this is a finding.
