When I first tried OBS, the Auto-confiuration wizard popped up. I told it I only wanted to capture screens, but it insisted I supply a stream key anyhow. Rather than create a bogus streaming account to get a key just to get past the wizard, I gave up on OBS for a while. I came back to OBS only when I failed to get Windows Game Bar to work properly. OBS is a good tool, don't let the wizard dissuade new users.
