+1 for wizarr! It also works for audiobookshelf. ( Brent actually already used mine to create an account on my audiobooks server when I recommended ADHD is awesome.)
Super handy for when you want to invite people to all your platforms at once with a single invite code. (Also does Romm if you have rom collections for emulation)
