The Screen Time feature on iOS 12 lets you monitor everything you do on your iPhone. It also lets you set App Limits so you don’t waste time doing things that are less important. By default, Screen Time uses your iPhone’s lock screen passcode. But you can change the Screen Time Passcode to something different.

How to Change Screen Time Passcode on iPhone

  1. Go to Settings » Screen Time.
  2. Tap Change Screen Time Passcode, then select Change Screen Time Passcode again.

  3. Enter your Old Screen Time Passcode.
  4. Then Enter New Screen Time Passcode and verify it.

That’s it. You’ve successfully changed the Screen Time passcode on your iPhone running iOS 12 and above.
