How To Use Safety Check

Safety Check allows you to review and reset access you’ve granted others to your accounts, location data, and more. Here are the steps to use it:

Access the Safety Check Screen

  1. Open Settings and tap on your name at the top of the screen.
  2. Select “Privacy & Security”.

Tap on “Safety Check”.

You’ll now see the main Safety Check screen.

Review and Remove Device Access

On the Safety Check screen, you can see and manage devices that are signed in to your iCloud account. This allows you to identify any unknown or unauthorized access.

To review and remove devices:

  1. Under “Review Devices Signed Into Your Account”, look over the list of devices.
  2. Tap any device to see details like the login date and location.
  3. To remove a device’s access, tap “Remove Device” and then confirm.

Reset Permissions and Data Access

You may have granted app permissions to access your contacts, photos, camera, microphone, or location data. Safety Check allows you to easily reset these permissions.

To reset app permissions:

  1. Under “Manage Access To Your Information”, tap “Review Shared Permissions”.
  2. For each app, toggle the sliders to turn off access to contacts, photos, camera, microphone, or location.
  3. Tap “Done” to confirm your changes. Access will be immediately reset.

You can also see which third-party services have access to your account data like calendars, reminders, photos, or email.

To reset account data access:

  1. Under “Manage Access To Your Information”, tap “Review Shared Account Access”.
  2. For each service, tap “Remove Access” to block further data access.

Use Emergency Reset

If you feel your iPhone is compromised, you can perform an Emergency Reset to immediately reset permissions and cut off access.

To perform an Emergency Reset:

  1. At the bottom of the Safety Check screen, tap “Emergency Reset”.
  2. Confirm that you want to perform a reset by tapping “Continue”.

Emergency Reset will sign you out of iCloud on your device, reset privacy permissions for apps, and limit sharing. Your Apple ID password will also be reset, so be sure you still have access to a trusted secondary device or recovery phone number.

This provides a clean slate and secures your account in just a few taps if needed. You can then review and re-enable sharing as desired.

How To Use Check In With Messages

  4. Tap “Check In” to initiate location sharing.

The Check In screen will appear with your location on a map. Your selected recipients will be notified that you have Checked In.

Choose a Check In Duration

When you initate a Check In, you can choose how long you want to share your location:

  • One hour
  • Until end of day

End a Check In Early
