I have several devices sharing the same Apple ID, one being an iPad (plus 2 iPhones, 2 Macs etc). I want to share my iPad PIN unlock code with others in my flat so they can use Spotify / control the Audio etc., but I don't want them to have access to anything else (e.g. my Apple account, my non-Apple email accounts).
Firstly, I don't believe there is any way (e.g. multiuser) way of me (e.g.) having my mail on there, and it not being available to anyone with the unlock code - correct?
Secondly, even if I delete my mail accounts, to what extent am I still in danger? Are secrets (e.g. passwords) shared between devices for Apps / Accounts? IE can people put them back without entering the password or restore the device to a state where it had the password? Can I stop the casual user deciding to buy lots of Apps? Is there a way to lock down the device less hammer-to-crack-a-nut than removing my Apple ID and all accounts or (e.g.) factory reset?
