# Configuring Access to Azure Resources Using a Managed Identity

For some Azure resources, the Commvault software supports the use of a managed identity on your Commvault access nodes, to give Commvault access to the resources. Using a managed identity is the securest and simplest way to give Commvault access to your Azure resources.

The type of managed identity that is supported—system assigned, user assigned, or both—depends on the type of Azure resource.

Note

If managed identity authentication is configured on an Azure VM, you cannot change the authentication type from the CommCell Console. To switch from managed identity authentication to Azure app and secret authentication for an Azure hypervisor, use the Command Center.

For instructions about modifying the authentication method, see Modifying Settings for an Azure Hypervisor.

## Procedure

1. Configure a system-assigned managed identity or a user-assigned managed identity on the Azure VMs that you will use as Commvault access nodes.

   For instructions, see Configure managed identities on Azure virtual machines (VMs).

2. To the managed identity, assign the required roles.

   For instructions, see Assign Azure roles to a managed identity.
