After Enabling finger print authentication on ubuntu 12.04, i found it frustrating as i needed to scan my finger print multiple times to get authenticated. So i disabled it to use password mechanism again.
To disable finger print authentication use the following command on ubuntu console:
sudo pam-auth-update
It will open a pop up window as show below.
uncheck the first two option. You can navigate through arrow keys and press space to check/uncheck the options. Then use "Tab" to navigate to Ok and press "Enter" to complete the process.
Finger print authentication will be gone.
