With the application Fingerprint GUI you can configure authorization using the fingerprint scanner. Configuring the application is quite flexible, and the interface is completely intuitive.

Unfortunately, manufacturers of fingerprint scanners still pay little attention to the Linux system and deprived of their software support. However, thanks to independent developers, we can use many of these devices under Linux. This is possible thanks to a set of Fingerprint GUI.
Installation into Linux Mint:
sudo add-apt-repository ppa:fingerprint/fingerprint-gui sudo apt-get update sudo apt-get install libbsapi policykit-1-fingerprint-gui fingerprint-gui
After installation launch Fingerprint GUI and enrol your fingerprints.
That should be all you need to do!
Try locking your screen, logging out and in, sudo in terminal and running graphical apps requiring root privileges.
GNOME users: The package policykit-
sudo apt-get install policykit-1-gnome sudo apt-get remove fingerprint-gui
KDE SC users: The above instructions for GNOME users apply to you as well, just replace “policykit-1-gnome” by “polkit-kde-1” throughout the text.
Note for Lubuntu users
lxdm does not properly support alternative authentication methods in the PAM stack. If you want to use fingerprint-gui with Lubuntu, you should install lightdm and lightdm-gtk-greeter.[/quote]
