Configuring System to use Fingerprint Verification

• For command line use, such as the virtual terminals or terminal emulator in a WM/DE.

• Graphical authentication is still a work in progress

To use fingerprint for sudo, press enter then swipe. Modify PAM configuration as root:

sed -i '1s/^/auth      sufficient  pam_fprintd.so\n/' /etc/pam.d/sudo
sed -i '1s/^/auth      sufficient  pam_unix.so try_first_pass likeauth nullok\n/' /etc/pam.d/sudo

Or for logins, press enter then swipe. Modify PAM configuration as root:

sed -i '1s/^/auth      sufficient  pam_fprintd.so\n/' /etc/pam.d/system-auth

Regardless, also modify polkit PAM configuration as root:

sed -i '1s/^/auth      sufficient  pam_fprintd.so\n/' /etc/pam.d/polkit-1
