Managed Apple ID
Like a personal Apple ID, you can use a Managed Apple ID to sign in to a personal device, sign in to a shared device, or to access Apple services including iCloud, iTunes U, and Apple School Manager. Unlike personal Apple IDs, Managed Apple IDs are owned and controlled by a school or district. The institution can reset passwords, limit purchasing and communications, and set up role-based administration. See Apple School Manager Help.
Note: To add a Managed Apple ID user to your site, both the Managed Apple ID and the site must be associated with the same managed organization.
