Fingerprint reader on Debian 13 ?

Hello,

I’m using Debian Trixie and I’ve discovered I have a fingerprint reader which is working after installing fprintd !
$fprintd-enroll is working
The GUI User configuration is working too (I can add a fingerprint)…

I can’t unlock my session with it, either at startup or on the lock screen (after a sleep).

There is no file /etc/pam.d/kde*
If I don’t put any password and then type Enter, nothing happens with my fingerprint.

Any idea ? Thanks !
