Possible to keep auto logging in from clients after full server reinstall?

[raulo1985]

Any reason you're not at least preserving the old Jellyfin config folder?
Do you need to clear out your Jellyfin settings when you clear everything off of your computer?

I'm using containers for my Jellyfin server, and when I update Jellyfin, all I have to do is download the new image and link it a copy of the old config folder.
After that, the container starts and all my clients work as before with no re-logging in needed.

Also, the cache folder shouldn't matter here for your issue.

Thanks for your reply. Sorry, but what do you mean by preserving the old Jellyfin config folder? You mean the one that was in the .config folder? I understand that Jellyfin doesn’t use it anymore (and I don’t see it either), and that all the config files are now located in the etc and var folders. So I thought that backing up and restoring those two folders, there weren’t other folders that need restoring.

At first I just wanted to preserve the server ID and tokens with the hopes of the clients logging in automatically, but starting with all the server settings at their defaults. When I do a clean install, I’ve always liked to setup everything from its defaults, including creating the libraries, users, etc. That’s why I first tried restoring only the device.txt and database files (ID and tokens), but it didn’t work. So I gave up on the idea of setting everything up from its defaults and just do a full restore (so the clients don’t have to log in manually), but to my surprise the behavior is the one I mentioned before: it gets to the log in page, passwords and users are preserved, but they don’t auto log in (except the iOS official app).

So, in my book and to my knowledge, by backing up the etc and var folders, I’m indeed doing a full backup. Or is there another folder I’m missing that I should backup and restore?
