On some Windows 8.1 and Windows Universal app, when login to some service (Google, Facebook, Twitch, ...) I see this window open and login box like this. I search with google but no help to find how to implement on my app.
Can anyone give me answer or link to this function?
It is the WebAuthenticationBroker
