How do I require Two Factor Authentication to log in?

Question

Running 12.04. I am trying to separate my wrapped-passphrase for my encrypted home folder to require a USB drive be present to login.

I followed the instructions here and added the drive to my fstab, put the wrapped-passphrase file on the drive, and then created a symbolic link back to ~/.ecryptfs. The drive mounts fine but the symbolic link doesn't seem to be connecting the two as when I login it flashes a purple screen for a fraction of a second than takes me back to the login screen. What am I doing wrong?

This thread details how to use a USB stick as your boot device, though for different reasons. I like the fact that without the stick the machine appears to have no OS on it.

Have you considered this: "How to Secure SSH with Google Authenticator’s Two-Factor Authentication"?

Its not a USB it is an app on our phone that generates a code.
