Fixed in Windows 10 mobile build 10.0.15250.0

Two-factor Authentication: The new build introduces a new two-factor authentication unlock mechanism for Windows 10 Mobile. With two factor unlock, an enterprise can enforce an additional security layer to their sensitive data via an MDM policy. Once two factor unlock is enabled, a phone user will have to enter a numeric pin followed by an enterprise-defined factor to unlock the phone. An example of an enterprise-defined factor is a companion device such as an NFC tag which can be used to unlock a phone using our Companion Device Framework sample app and documentation.

AppLocker Improvements: A number of customers have provided feedback on the warning prompts for apps that are blocked by enterprise policies. We’ve improved the UX and updated the MDM SyncML scripts associated with the policies. Application restrictions can be configured by either the ApplicationManagement CSP or AppLocker CSP.

  • Automatic reconnection on resume.
