Using fingerprint scanners for login is cool. Sure, it's insecure, but who cares about that :-). It's awesome!
Do enroll more than one finger, and have a fallback mechanism though...
# Install fingerprint software.
# You can play around with fprint_demo to try it out...
sudo aptitude install fprint-demo libpam-fprint libfprint
# Enroll the index finder. See pam_fprint_enroll --help for details
pam_fprint_enroll --enroll-finger 7
# Edit your PAM configuration to enable fingerprint login
# Fallback to password if it fails.
# emacs /etc/pam.d/commond-auth
# Add something like:
# Fingerprint
auth sufficient pam_fprint.so
You could also require both, but that's just awkward :-). And if finger print scanning breaks, it's a PITA.
