ThinkFinger is a driver for the SGS Thomson Microelectronics fingerprint reader found in most IBM/Lenovo ThinkPads.


Get if from here.



Use "tf-tool" to test ThinkFinger. You'll have to run this as root because a direct access to the usb devices is needed. Run "tf-tool --acquire" to generate a test.bir and "tf-tool --verify" to see if it identifies you correctly. "tf-tool --add-user <username>" acquires and stores your fingerprint in /etc/pam_thinkfinger/username.bir, which is needed for an authentification with pam.


PAM is the Pluggable Authentication Module, invented by Sun.


Change the file /etc/pam.d/other to look like this if you want to use your fingerprint to authenticate yourself on logon:

auth		include		thinkfinger
account		include		thinkfinger
password	include		thinkfinger
session		include		thinkfinger
#auth		required
#account	required
#password	required
#session	required


Change this file to confirm the "su" command with a finger-swipe!

auth		include 	thinkfinger
auth		required
account		required
session		required
