I'm a listener of the Security Now Podcast from TWiT network and a couple of episodes ago Steve Gibson spoke about a One Time Passwords system that he had created which is denominated Perfect Paper Passwords and he explained how it works.

The community has actually taken this security system and have developed ways to implement this technology into various systems so that it can be used to better secure servers and other applications. There is one project in Google Code which created a PAM module for Linux and MacOS X so that the user can implement the PPP.

I have taken this into consideration and applied it to my SSH server so that my log ins require for me to enter an OTP. For more details on how this work you can check episodes 115 and 117 from Security Now. I'll try to explain how this work, though on a more general level, and how I managed to implement this on my current infrastructure.
