UE4 Game Launcher and Login?

A few questions here. I am aware of Launchpad as a launcher to patch and start your UE4 game. I was curious if it was possible to login via a launcher like Launchpad and perhaps send an auth token or something into the UE4 game to verify you are logged in and pull information about a user into the game. Otherwise, do we need to make the login happen within the game itself?

Basically the way I want a user to begin and see the game. Would be open the launcher. It checks for updates. The user logs into their account. It launches the game and brings them to the main menu. Here it would display their account username, any currency, etc all gathered from them logging from the launcher.
