Can someone provide any information/links on how to implement 2 factor authentication with ssh? Do I need any extra software? Is there any open source tool that can help? Thank you in advance.
You mean like requiring both a password and a key before a user is logged in? This is possible on most SSH servers, but naturally configuration is specific to whatever ssh server you're running. (Unfortunately, I think OpenSSH is not one of the servers that supports requiring both a key and a password without PAM or source modification. Someone please correct me if I'm mistaken.) There's lots of other two-factor approaches (RSA devices seem popular, though expensive), but a password + a key is cheap and effective.
