Go to Settings > Privacy & Security > Safety Check. Manage Sharing & Access goes through people, apps and devices one at a time. Emergency Reset stops all sharing at once.

How to do it

1. 01

   Open Settings > Privacy & Security > Safety Check.

2. 02

   Choose Manage Sharing & Access if you want to go item by item: people, location, apps, and devices.

3. 03

   Choose Emergency Reset only if you want the fast version. It stops sharing and reviews sign-in in one pass.

4. 04

   Read each confirmation. You can restore sharing later, but not by undoing a single button.

Use Manage Sharing when you are not in a hurry. Emergency Reset is for a situation where speed matters more than checking each row. Neither one removes another person's copies of messages you already sent.
