 > As of July 2024, the Data Explorer exposed in the Azure portal does support Azure Cosmos DB role-based access control. The Azure Cosmos DB Explorer at [https://cosmos.azure.com](https://cosmos.azure.com) also supports this without the need to specify a query parameter. The previous method of using `https://cosmos.azure.com/?feature.enableAadDataPlane=true` to enable this functionality is still honored and will force the use of Microsoft Entra identity for your data requests.
 
-Azure Cosmos DB role-based access control within Data Explorer (either within the Azure Portal or at [https://cosmos.azure.com](https://cosmos.azure.com)
+The use of Azure Cosmos DB role-based access control within Data Explorer (either exposed in the Azure Portal or at [https://cosmos.azure.com] (https://cosmos.azure.com)) is governed by the **Enable Entra ID RBAC** setting. You can access this setting via the "wheel" icon at the right-hand side of the Data Explorer interface. 
+
+The setting has three possible values:
+- **Automatic (default)**: In this mode, role-based access control will be automatically used if the account has [disabled the use of keys] (#disable-local-auth). Otherwise, Data Explorer will use account keys for data requests.
+
+- **True**: In this mode, role-based access will always be used for Data Explorer data requests. If the account has not been enabled for role-based access , then the requests will fail.
+
+- **False**: In this mode, account keys will always be used for Data Explorer data requests. If the account has disabled the use of keys, then the requests will fail.
