I send them an email that contains a link to jellyfin.mydomain.tld with their new username and password, plus a few tips for how to get the most out of it (I wrote a template a few years ago).
It's not any more work for me than giving a user library access on Plex, but it does require I have a reverse proxy and a domain.
Sure. I think this was originally written by GPT-3.5 but I've tweaked it a lot since then. I try to keep it short enough that people will actually read it all the way through while still answering some of the more common questions.
Subject: Welcome to <my real name>'s Jellyfin Media Server
Hi there,
Welcome aboard! You now have access to my media server and can enjoy my library of Movies and TV Shows.
Here are your login details:
Link: https://{JELLYFIN_DOMAIN} (bookmark this!)
Username: {USERNAME}
Temporary Password: {PASSWORD}
Please update your password as soon as you log in for your security:
Log in with the information above. Click your profile icon (top-right corner, looks like a person). Choose "Profile" (same icon again). Enter the current password and your new chosen password, then click Save.
Tips:
Jellyfin works like any other streaming platform, you can browse, watch, and favorite. It always keeps your place and remembers what you were watching so it's easy to come back to.
Jellyfin can be used in a web browser, or you can find apps for phones, tablets, and some TVs.
Browse the full list of movies or shows available by clicking the boxes under "My Media" on the home page.
You can request new media by visiting {REQUEST_DOMAIN} and logging in with your same Jellyfin username and password. Please only request things you are sure you will watch in the next month or two.
Jellyfin and Ombi are software packages that I run on my own computer, but I did not build them.
Please reply to this email if you have any issues.
Enjoy!
