I got a new Dell laptop and I used to login into Windows using webcam authentication. Now I have removed Windows and installed Ubuntu but I could not find any application for face authentication. How can I do this? Thanks.

There is a program called pam-face-authentication, although it is not in the repositories, so you will have to install it by following the instructions - there is a ppa.

The documentation site doesn't seem to work but you can try looking in /usr/share/doc/pam-face-authentication to find documentation once you have installed.

You should note that the security of alternative authentication methods such as fingerprint readers and face recognition is questionable, i.e. not as good as a strong password.

Great stuff. Thanks. I am using the laptop for home use and not for work so I am not much concerned about security. Just one question - Is it safe? it won't break my system, right? –  user8592 Feb 2 '11 at 9:03
    
It should be OK but with PPA packages there is always a risk. See the warnings on this page. –  dv3500ea Feb 2 '11 at 9:43
