You can create accounts for Jellyfin that allows people to log in. However, the way you serve it to them is your responsibility. In my case, I set up my system with DDNS to work off a personal domain that anyone can connect to with the correct credentials. It’s a bit more work to set up, but I like it better in the long run.
My wife and I were just mentioning the other day how we can have video chats with family half way around the world, for free. When we were kids making a long distance call to someone a few counties away was a big deal and we didn’t talk long because it would cost too much. Wild stuff.
