With the ThinkFinger driver, openSUSEŽ supports the fingerprint reader by UPEK/SGS Thomson Microelectronics included with some IBM and Lenovo ThinkPads. The same fingerprint reader can also be found in other laptops and either as a stand-alone device or built into some USB keyboards. For more details, refer to http://thinkfinger.svn.sourceforge.net/viewvc/*checkout*/thinkfinger/README.in. If your system includes the fingerprint reader, you can use biometric authentication in addition to standard authentication via login and password. After registering their fingerprint, users can log in to the system either by swiping a finger on the fingerprint reader or by typing in a password.
If the hardware check detects the fingerprint reader integrated with your
laptop (or connected to your system), the packages libthinkfinger
, pam_thinkfinger
, and yast2-fingerprint-reader
are automatically installed.
Currently, only one fingerprint per user can be registered. The user's
fingerprint data is stored to
/etc/pam_thinkfinger/
.
To manage fingerprint authentication, either use YaST (see Section 27.2, “Managing Fingerprints with YaST” or the
tf-tool command line tool which also offers additional
options (see Section 27.3, “Managing Fingerprints with tf-tool”.login

The PAM module pam_thinkfinger
supports fingerprint
authentication for the following applications and actions (although you may
not be prompted to swipe your finger in all cases):
Logging in to GDM/KDM or a login shell
Unlocking your screen on the GNOME/KDE desktop
Starting YaST and the YaST modules
Starting an application with root
permission:
sudo or gnomesu
Changing to a different user identity with su or
