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.
I prefer Jellyfin over Plex. Plex has become too bloated. Jellyfin is free, open-source, and well maintained. I have it running on Docker on my NAS, feeding multiple devices, accessible on every platform I use, and it hasn’t failed me. I was a lifetime subscriber of Plex before I made the switch, and haven’t looked back.
LTT did a great video about Jellyfin. Keep in mind that this video is 5 months old, and they have had updates since.
Definitely Jedi Knight II: Jedi Outcast
Update: They weren’t able to renew the domain. They still own it, but they are using makemkv.info for the time being. Seems to be the forums only, for now.

For 5th and 6th period in middle school, in the early 90s, I was in the same lab and had complete access to the computers. Rather, I was in charge of them. I was a TA for one period and it was a free elective for another period. I don’t remember the details…but somehow I was there for both periods every day.
The teacher who ran the lab just left it all up to me. So, I installed games on all of the computers. Oregon Trail, DOOM, and Q*bert were the three that I remember.
Students would be sent up to the computer lab, on a daily basis for both periods. A lot of times the teacher who ran it would go run errands since I had it covered. When those kids came up, the entire lab just played games.
Also, since it was 6th period, I’d have the honor of shutting down the entire school network and systems at the end of the day. I’d get to call teachers and tell them to get off so I could shut it down. Some times I wouldn’t contact them, and I’d just kick them off the network and shut down anyway.
It was a fun time.
