Q: Why do you need my password/passcode?
A: The passcode is required for testing your device after the repair, to make sure we’ve done the job properly. This usually just involves moving icons around on the home screen, accessing the camera if it’s been replaced, etc. Your personal data, photos etc will not be accessed. You do not need to provide your passcode but our device testing will be limited by this.
This will definitely be required for data recovery service though.
