“Grab an app called jellyfin, type in this number, pick the profile with your name, password is X”

It’s not that different than “Grab an app called plex, here’s the username and password, pick the profile with your name” (or sign up yourself and I’ll share it with you)

Can you point me in the direction of doing this in jellyfin? I keep finding guides and things for tailscale and whatnot but I too would like to just be able to install jellyfin on something and connect to my server.
