Login issue

[pipozor]

Hello,

Since I updated Jellyfin to the last version I now get a Login form.
I never seen it before. I do not remember to have set any username/password. I think I did not do that.
Before update, I was just connecting to server and that was directly working without any username/password.

* Connect option not working
* Quick connect, i do not understand how it work (where to type the code)
* Recovering password, not working too as I do not have any username.

Please see attached pictures.

I do not want to lose my database and all hard works I setup in collections etc... 
Any help will be appreciated thank you.
