I've successfully used Google Authenticator on iOS. It looks like this article covers setting up the necessary PAM modules and configurations to get sshd working with TOTP. http://delyan.me/securing-ssh-with-totp/ This will require that you supply the 6-digit code provided by Google Authenticator. If you want something where you just accept a push notification or similar, take a look at Duo Mobile. https://duo.com/docs/duounix Chris On Mon, Mar 27, 2017 at 09:08:58PM -0400, David Mehler wrote:

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.
