iPhone battery replacement - Password Req
My friend was getting their iPhone 6s battery replaced in the Palo Alto store. When they handed their iphone to the apple genius, they needed to turn off Find my iPhone (sure), as well as provide both their iPhone's Passcode AND their Apple ID Password.
This freaked me out honestly. Why is this needed? Is there an official statement as to what is needed in order to have one's iPhone serviced.
I just don't feel comfortable giving up both my Passcode and my Apple ID Passphrase. This seems to be a huge attack surface to be honest - and as the genius was typing into their iPad my friend's passcode and passphrases, I thought about all the ways this information could be leaked.
After getting their iphone back, I had to help them change both their passcode/phrases. Huge pain in the rear. So I'm wondering if there is a document that I could print/point to on an official Apple site regarding what information is needed and not needed? Thanks in advance.
