How to get the mac address of HoloLens 2 in Unreal Engine?

Question

I would like to get the mac address of HoloLens 2 in Unreal Engine using either C++ or blueprint. Is there a way to get the mac address/serial number or any sort of solution to identify the uniqueness of the device?

Answer 1

Since HoloLens App is a UWP app, you can use WinRT API methods contains in WinSDK. For example, you want to get the identifier of the local device would need EasClientDeviceInformation.Id in Windows.Security.ExchangeActiveSyncProvisioning namespace.
