Check Contents

Review configuration settings to confirm "Allow Handoff" is disabled.

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 Handoff" is unchecked.

Alternatively, verify the text "<key>allowActivityContinuation</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 Apple iOS/iPadOS management tool containing the restrictions policy.
5. Tap "Restrictions".
6. Verify "Handoff not allowed" is listed.

If "Allow Handoff" is checked in the Apple iOS/iPadOS management tool, "<key>allowActivityContinuation</key> <true/>" appears in the configuration profile, or the restrictions policy on the iPhone and iPad does not list "Handoff not allowed", this is a finding.
