    This product contains a code plugin, complete with pre-built binaries and all its source code that integrates with Unreal Engine, which can be installed to an engine version of your choice then enabled on a per-project basis.

This is a Unreal Engine 4 plugin for In-Game Twitch Authentication.

The idea for this plugin came while watching the development stream from a fellow Twitch streamer called Wheeze202. He provides his Twitch subscribers early development builds of his current project Galdur to playtest and give him feedback on. His infrastructure was simple, he simply whispered the link to the build when a subscriber entered a command in the Twitch chat.

I saw some flaws in this approach, because now you had to rely on the subscriber to keep the link a secret. I thought there must be a better way. So, I set out to build this plugin to let any Twitch game developer have the ability to let potential subscriber play testers authenticate in-game. Now only subscribers can play the game.
