What it does

This policy setting lets you determine whether the integrated unblock feature will be available in the logon User Interface (UI). In order to use the integrated unblock feature your smart card must support this feature. Please check with your hardware manufacturer to see if your smart card supports this feature. If you enable this policy setting, the integrated unblock feature will be available. If you disable or do not configure this policy setting then the integrated unblock feature will not be available.

These deployment candidates come from the ADMX template; they are separate from the native CSP mapping above.

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
