I often have students who don’t know their Apple ID or can’t remember their password. Without these, you can USE our iPad, but you can’t update or get apps or backup to the iCloud. Apple.com is there to help you out.
Manage your Apple ID: An Apple ID is your user name for everything you do with Apple: Shop the iTunes Store, enable iCloud on all your devices, buy from the Apple Online Store, make a reservation at an Apple Retail Store, access the Apple Support website, and more.
Find your Apple ID: If you can’t remember your Apple ID, just provide some information on this page at Apple support and they’ll find it for you. Then they’ll help you reset your password.
Reset your Password: You can change or reset the password for your Apple ID account by providing some information to Apple. Just follow this link.
