Heya,

If you're feeling adventurous and you have a fingerprint reader, read on. The feature is detailed at: https://fedoraproject.org/wiki/Features/Fingerprint

You'll need: - install the latest git snapshot of libfprint: http://koji.fedoraproject.org/koji/taskinfo?taskID=917627 - rebuild and install the fprintd and fprintd-pam RPMs: http://hadess.fedorapeople.org/fprintd/fprintd-0.1-1.fc10.src.rpm (See also: https://bugzilla.redhat.com/show_bug.cgi?id=469955 ) - Modify your /etc/pam.d/system-auth-ac file, and add the line: auth sufficient pam_fprintd.so before the line: auth sufficient pam_unix.so ... See also https://bugzilla.redhat.com/show_bug.cgi?id=469418

You can now enroll a new fingerprint using fprintd-enroll, list registered fingerprints using fprintd-list, and test verification using fprintd-verify.

If you don't enroll a fingerprint, you just won't be asked for a fingerprint.

Cheers

PS: If you break your system and can't log in anymore, it's not my fault. Boot in single user mode, and remove the pam_fprint.so line from the pam.d configuration.
