* Microsoft Azure Managed Identities are available only for services running on Azure when a "system assigned" identity is enabled.

|

* A system assigned managed identity is restricted to one per resource and is tied to the lifecycle of a resource.
|
||
* You can grant permissions to the managed identity by using Azure role-based access control (Azure RBAC).
|
||
* The managed identity is authenticated with Microsoft Entra ID, so you don’t have to store any credentials in code.
