 Azure Virtual Desktop uses Azure role-based access control (RBAC) to control access to resources. There are a number of built-in roles for use with Azure Virtual Desktop  which is a collection of permissions. You assign roles to users and admins and these roles give permission to carry out certain tasks. To learn more about Azure RBAC, see [What is Azure RBAC?](../role-based-access-control/overview.md).
 
-The standard built-in roles for Azure are Owner, Contributor, and Reader. However, Azure Virtual Desktop has additional roles that let you separate management roles for host pools, app groups, and workspaces. This separation lets you have more granular control over administrative tasks. These roles are named in compliance with Azure's standard roles and least-privilege methodology.

 Azure Virtual Desktop doesn't have a specific Owner role. However, you can use the general Owner role for the service objects.
 
 The built-in roles for Azure Virtual Desktop and the permissions for each one are detailed below. The assignable scope for all built-in roles are set to the root scope ("/"). The root scope indicates that the role is available for assignment in all scopes, for example management groups, subscriptions, or resource groups. For more information, see [Understand Azure role definitions](../role-based-access-control/role-definitions.md).
