Now start.

Before installing fprint, make sure your hardware is supported, you can see the list on here.

Wiki fprint on Arch

https://wiki.archlinux.org/index.php/fprint    

Check lsusb first, on my machines:

Bus 001 Device 003: ID 147e:2020 Upek TouchChip Fingerprint Coprocessor (WBF advanced mode)

$sudo pacman -S fprintd 

imagemagick might also be needed.

Configuration:

$sudo su
#groupadd plugdev
#gpasswd -a yourusername plugdev
#chgrp -R plugdev /dev/bus/usb/

Now set your finger: For User:

$fprintd-enroll

For Su: login with su by error: su: Authentication failure

You can reset the password: sudo passwd root

After:

$su
#fprintd-enroll

You will be asked to scan the given finger. Swipe your right index finger five times. After that, the signature is created in /var/lib/fprint/.

Then now modify /etc/pam.d/...

For Login gdm/kdm:

Modify: login

$sudo vim /etc/pam.d/login

add this

 auth required pam_env.so
 auth sufficient pam_fprintd.so
 auth sufficient pam_unix.so try_first_pass likeauth nullok
 auth required pam_deny.so
 
 #auth required pam_securetty.so
 # ...

And for /su, /sudo same as above.

  $sudo vim /etc/pam.d/su
  $sudo vim /etc/pam.d/sudo  

OK. Now try fingerprint.
