Add two-factor authentication to your ssh in 30 seconds.
- chris-tucker 13y agoSo what if the site goes down? I can't ssh since force command is failing?
- nobodyshere 13y agoHopefully there's a fallback mechanism or a backup code. Otherwise it all looks really shady.
- nobodyshere 13y agoCan anyone tell me if that's really worth it? Looks like a bit of an overkill considering the protection given by ssh keys.
- Oletros 13y agoDoes it works just with SMS?
- RossM 13y agoI've used the libpam module for Google Authenticator[0] before, the difference being that it isn't dependant on the availability of a third-party service, but you have to be much more careful about losing your device. That said Authy do have pretty great uptime[1] Nice for production servers, but becomes a an annoyance after the cool factor wears off for servers that don't really need it :) Installable on aptitude using libpam-google-authenticator (guide [2]).

- nickbyfleet 13y agoI looked at the site for some time and couldn't find an answer to my question. Does anybody know if the SMS is just for US cellphones?
