Physical hacks are often used to get into mobile devices. Apple helps mitigate this by asking if you want to trust connected computers. But, in the iOS 12 release Apple has made it even more difficult getting into a locked iPhone by letting users disable USB accessories if the phone has been locked for over one hour.

To disable USB accessories, go to

  1. Settings
  2. Face ID & Passscode
  3. Toggle the USB Accessories switch so it’s off.

Now USB access will be restricted after one hour of inactivity. There are some exceptions. For example, you’ll still be able to charge your phone.

Keep in mind when you connect to a computer to sync photos—or something similar—the connection will timeout after one hour of the phone being locked.
