Fix Recommendation

Install a configuration profile to disable the AutoFill capability in the Safari app.

Check Contents

Review configuration settings to confirm "Enable autofill" is unchecked.

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 "Enable autofill" is unchecked.

Alternatively, verify the text "<key>safariAllowAutoFill</key><false>" appears in the configuration profile (.mobileconfig file).

On the iPhone and iPad:
1. Open the Settings app.
2. Tap "General".
3. Tap "Profiles & Device Management" or "Profiles".
4. Tap the Configuration Profile from the iOS management tool containing the management policy.
5. Tap "Restrictions".
6. Verify "Auto-fill in Safari not allowed" is present.

If "Enable autofill" is checked in the Apple iOS/iPadOS management tool, or "<key>safariAllowAutoFill</key><true>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Auto-fill in Safari not allowed", this is a finding.
