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 and portals (for example, iCloud, iTunes U, Apple School Manager, Schoolwork). 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.
Teachers using a Managed Apple ID can use Schoolwork to share and receive content, collaborate with students and view progress data for students at their school. Schoolwork teachers are given 200 GB of iCloud Drive storage.
See What are Managed Apple IDs in Apple School Manager? in the Apple School Manager User Guide.
Note: A Managed Apple ID is referred to as a school account in the Schoolwork User Guide for students.
