Password authantication not showing in KDE after installing fingerprint-gui

Hi All,

I installed fingerprint gui for authenticating fingerprint gui from AUR.
Now even after uninstalling the package. System seem to straight login into my user.
Do I need to do some changes into my sudo or pam?
I have put back polkit-kde-authentication-agent-1.desktop to /etc/xdg/autostart/ but no luck.

Thanks in advance.
