What Is Emergency Reset on iPhone?

Safety Check is an Apple privacy and security feature that lets you manage who has access to different things you can share, like location, purchases, notes, etc. Emergency Reset lets you instantly stop sharing all your information with everyone, effectively locking down your account against everyone but yourself. You can also go through and select manually who to stop sharing with, change your Apple ID password, remove devices from your Apple ID, and other important security measures.

If you think someone has access to your location, apps, or Apple ID that shouldn't, Emergency Reset can shut that down fast. Whether you suspect someone hacked your account and you want to immediately stop sharing information with apps and change your Apple ID password, or someone you trusted with your location no longer has that trust, you can stop sharing in a matter of seconds. Here's how to use Emergency Reset in Safety Check.

  10. Finally, you'll review whether you want to update your Apple ID password, who your Emergency SOS contacts are and if you'd like to add or remove any, whether you want to update your device passcode (helpful if anyone learned your passcode who shouldn't), and if you want to turn on iCloud Private Relay.

Remember, tapping Reset is the fastest way to shut down all sharing, but if you have a little extra time and don't want to start over from scratch, Manage Sharing & Apps might be the way to go.


  • How do I stop sharing with someone on iPhone? You can use the Safety Check feature to review who has access to what and revoke that access if needed, or you can go into individual apps, like Find My, Notes, Reminders, etc., and do it directly from there.
  • Does your iPhone tell you when someone stops sharing? They won't receive a notification when you revoke sharing privileges, but they'll not longer be able to view what you stopped sharing with them, so No Location Available would show up in Find My, for example.
  • How can I tell if someone has access to my iPhone? You can review who you are sharing what with in Safety Check in Settings. However, if you suspect someone has access to your Apple ID, it's best to change the password immediately.
