Assign Microsoft Entra roles at different scopes

In Microsoft Entra ID, you typically assign Microsoft Entra roles so that they apply to the entire tenant. However, you can also assign Microsoft Entra roles for different resources, such as administrative units or application registrations. For example, you could assign the Helpdesk Administrator role so that it just applies to a particular administrative unit and not the entire tenant. The resources that a role assignment applies to is also called the scope. This article describes how to assign Microsoft Entra roles at tenant, administrative unit, and application registration scopes. For more information about scope, see Overview of role-based access control (RBAC) in Microsoft Entra ID.

Prerequisites

• Privileged Role Administrator.
• Microsoft Graph PowerShell SDK installed when using PowerShell.

For more information, see Prerequisites to use PowerShell.
