Are you trying to find your Twitch Stream key? The Twitch stream key has been something that people have been searching for years! It is quite hidden.. I know. Twitch Stream key page may change it’s place in the future as it has earlier done so.
BTW! If you are running with OBS Studio, OBS.Live or StreamLabs OBS. There is a button where you connect your OBS straight up to Twitch. I highly recommend that since you get immediate access for things like your Twitch chat and tools to change game, title etc.
Go into the Twitch settings page
Head over to the Channel and Videos page
Copy your Stream Key and Enable “Store past broadcasts”
That’s basically it! Now you can paste the Stream Key in your preferred streaming software and get to streaming. Store past broadcasts were a little extra tip for this whole thing! I’m pretty sure you would like to see VOD:s of your stream as well so it’s a good thing to setup enabled from the start.
