Fix Recommendation

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

Configuration Profile Key: safariAllowAutoFill

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 "VPN & Device Management".
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, "<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.
