Seems this is a very common query considering the search results on google. At least for macs they require an admin account to be setup they can use. For ios apple support seems to only mention the following. https://support.apple.com/en-us/HT201557 https://support.apple.com/en-us/HT201557 > Have your Apple ID password ready.

This policy is in force to prevent unauthorized persons from servicing your device without your knowledge. If you don't remember your Apple ID and Password, please go to iForgot. If the screen was working I think the right thing to have done was just wipe the phone and give it to them. If it was not working that’s a tough spot.
