I understand. I was working on a newer Panel that does allow for multiple users, then got sidetracked, and that does use Twitch Authentication, it is just that, unless I perhaps setup a redirect service myself for folks from my own server, I am not sure how to easily have Twitch have configurable redirects. So, it does require an additional application to be setup by each individual and to install those keys. Maybe that is ok for the few (I think it’s few!) folks that run a VPS and want to give out access to multiple people.
I am hoping to make it back to that newer Panel at some point for multiple users, it just requires a huge amount of time and lately my real life job has been sucking up more of that than usual!
