[Blind-sysadmins] 2 factor authentication, google authenticator accessibility, and sshd configuration

Hello, I realize that's a complex subject. Let me break it down. First, is anyone using google authenticator to implement two factor authentication with a service? I lost a google account password, forgot it is more like it, so I went in and google sent my phone a sms message, that I just had to open and then I was logged in. This is a capability i'd like to have with my services, openssh sshd to be specific. If anyone is using this or has additional information i'd like to know about it. Thanks. Dave.
