wow, thanks a lot for this PR :D

I've built an docker image with your changes. Creating a new account with new QuickConnect method works flawlessly if Enable New Jellyfin Sign-In is enabled :)

However, QuickConnect functionality is missing from Linked Accounts settings when trying to link a Jellyfin Account. And since my Jellyfin users are using OIDC-based login for Jellyfin - and they therefore don't have a password they could enter there - linking their Jellyfin accounts is not possible without QuickConnect functionality....

Have you thought about adding QuickConnect there as well?

EDIT:
Additionally, an option to disable username/password-based Jellyfin logins would also be great. Currently, I can only completely disable the Login Method Jellyfin Sign-In, there is no option to select each other or both login methods.

Good catch. I forgot about that. Will add.

This is out of scope of this PR. This functionality is already there in the oidc pr.

Great, thanks!

I am not sure if I misunderstood you...
My current (jelly)seerr image actually has both functionalities included: OIDC and your QuickConnect PR.
I meant a functionality to enable/disable QuickConnect manually - something like this:

It's not that important to me, but I was thinking of people who, for example, have disabled the QuickConnect feature in Jellyfin anyway.

EDIT:
Just tested it. When I disable QuickConnect on Jellyfin and activate Jellyfin Sign-in on Jellyseerr, QuickConnect is still visible on Jellyseerr Sign-in page and I get this error message:

Ah. Still out of scope of this pr. That option has to be added in the oidc pr once this pr is merged.

I just tested your latest changes. Linking my account using QuickConnect works now.

One thing I just came across: I found a behaviour I am not sure whether that's intentional or not.

1. Before linking Jellyseerr+Jellyfin accounts, my Jellyseerr account was created using OIDC (Authelia) and labeled as Local User.
2. After linking Jellyseerr+Jellyfin accounts, my Jellyseerr account is labeled as Jellyfin User. At Linked Accounts I do have the possibility to remove my OIDC (Authelia) account but no possibility to remove my Jellyfin account:

3. For OIDC, the _Delete_ button is even visible when OIDC is the only linked account and the only authentication method. But that's probably something I need to raise at OIDC PR anyway... :)

Removing jellyfin account is also an oidc pr thing :)
