I’ll probably get the details wrong but my understanding is that when you sign in, you get an authorization token. That token is valid for some period of time, let’s say 48 hours. You can use that cached token but let’s say it’s on your phone and not your TV. Maybe you haven’t used Plex on the TV this week. Want to use your TV, out of luck. Want to use a different local account, out of luck. Want to use Plex longer than the token is good for, out of luck.

I was briefly confused how an open source flashlight firmware had anything to do with this… then I noticed this post wasn’t in the Flashlight forum. So apparently Anduril is a war contractor AND a great flashlight firmware but are not related at all.
