Which type of Apple ID is required for User Enrollment?

User Enrollment, designed for BYOD, requires a Managed Apple ID to separate personal and managed data cryptographically. Created via Apple Business Manager (ABM) or Apple School Manager (ASM), Managed Apple IDs enable organizational policies while preserving user privacy. Personal Apple IDs (options A and C, the same) are not used for User Enrollment, as they lack organizational control. There’s no “Shared Apple ID” (option D); Shared iPad uses Managed Apple IDs differently. TheApple Platform Deployment Guidemandates Managed Apple IDs for User Enrollment.
