Automatic login

Hi,
I’m using jellyfin 10.6.4-1 on debian buster.
I’m new be with jellyfin , i have to admit.

I would like to know if there is a way to configure an automatic login for a particular user.

I have seen , its possible to configure a pin code it the user profile
So far i did not quite understood, what it was for.

What i noticed therefor, is that on the login screen, if you replace your password
with the pin code, you get in too.

What i’ would like for instance would be to be able to call jellyfin as such or similar

e.g

http://dum1:8096/web/index.html&pincode=1234&user=jdum

and your in for the user (jdum) registered with this pincode.

Any help ?

Best Regards
Jacques
