Q: If you dont remeber you restrictions passcode how to erase and restore

If you lose or forget your Restrictions passcode, you'll need to erase your device and then set it up as a new device to remove the Restrictions passcode. Restoring the device using a backup won't remove the passcode.

Hi Sheryl

As you have forgotten your Restrictions passcode, you will need to erase your device and then set it up as new in order to remove or change the Restrictions passcode.

There is no way around this feature.

If you have a backup of your device that was made before Restrictions was turned on, you may then wish to restore it from that backup.

If you instead restore from a backup that was made when Restrictions was already turned on, then the restrictions will also be restored.
