Fix Recommendation

Install a configuration profile to allow only 10 or fewer consecutive failed authentication attempts.

Configuration Profile Key: maxFailedAttempts

Check Contents

Review configuration settings to confirm that consecutive failed authentication attempts is set to 10 or fewer.

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 "Maximum number of failed attempts" value is set to 10 or fewer.

Alternatively, verify the text "<key>maxFailedAttempts</key> <integer>10</integer>" appears in the configuration profile (.mobileconfig file). It also is acceptable for the integer value to be less than 10.

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 "Max failed attempts" is listed as "10" or fewer.

If the "Maximum number of failed attempts" is more than 10 in the iOS management tool, "<key>maxFailedAttempts</key> " has an integer value of more than 10, or the password policy on the iPhone and iPad does not list "Max failed attempts" of 10 or fewer, this is a finding.
