Two-factor SSH authentication via Google secures Linux logins

Last week's TechMail was Two-factor SSH authentication via Google secures Linux logins which talks about using Google two-factor authentication with SSH (and PAM in general). I really like it and it works quite well although the comments in the TechMail indicate another option called Duo for two-factor authentication that sounds really interesting as well.
