Check Contents

Review configuration settings to confirm that Siri is disabled on the Lock screen.

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 Siri while device is locked" is unchecked.

Alternatively, verify the text "<key>allowAssistantWhileLocked</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 "Siri while locked not allowed" is listed.

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