 ## Authorize access to managed identities
 
 OpenAI supports Azure Active Directory (Azure AD) authentication with [managed identities for Azure resources](../../../active-directory/managed-identities-azure-resources/overview.md). Managed identities for Azure resources can authorize access to Azure AI services resources using Azure AD credentials from applications running in Azure virtual machines (VMs), function apps, virtual machine scale sets, and other services. By using managed identities for Azure resources together with Azure AD authentication, you can avoid storing credentials with your applications that run in the cloud.
