+### Which Azure RBAC permissions are required to use a managed identity on a resource?
 
 - System-assigned managed identity: You need write permissions over the resource. For example, for virtual machines you need `Microsoft.Compute/virtualMachines/write`. This action is included in resource specific built-in roles like [Virtual Machine Contributor](../../role-based-access-control/built-in-roles.md#virtual-machine-contributor).
 - Assigning user-assigned managed identities to resources: You need write permissions over the resource. For example, for virtual machines you need `Microsoft.Compute/virtualMachines/write`. You will also need the `Microsoft.ManagedIdentity/userAssignedIdentities/*/assign/action` action over the user-assigned identity. This action is included in the [Managed Identity Operator](../../role-based-access-control/built-in-roles.md#managed-identity-operator) built-in role.
