Account-driven enrolment methods with Apple devices
Account-driven User Enrolment and account-driven Device Enrolment provide a seamless, secure way for users and organisations to set up Apple devices for work by signing in with a Managed Apple Account.
This approach allows both a Managed Apple Account and a personal Apple Account to be signed in on the same device, with complete separation of work and personal data. Users maintain privacy over their personal information, and IT supports work-related apps, settings and accounts.
