If you are looking for a clean reliable two-factor auth system, I highly recommend Duo: http://www.duosecurity.com/

I've been using them across a half dozen personal machines for quite a while now, looking to roll it out at work as well.

Right, Duo is great. Love the fact you can install it over the whole enterprise including applications, blogs (Wordpress), vpns, and ssh.
