+#### Managed identity support for SMB Azure file shares is now generally available
+
+Azure Files customers can now use managed identities to allow Windows and Linux virtual machines (VMs) to access SMB Azure file shares using identity-based authentication with Microsoft Entra ID. This capability enables applications and virtual machines to securely access Azure Files without secrets, passwords, or key distribution. The GA release includes AKS workload identity support, co-existence of application identities and end-user identity access on the same storage account, and simplified enablement via the Azure portal.
