What is an Apple ID
According to Apple, "An Apple ID is the login you use for just about everything you do with Apple, including using iCloud to store your content, downloading apps from the App Store, and buying songs, movies, and TV shows from the iTunes Store."
In order to even have access to WSU iPads you must have an Apple ID.
