SSH Two-Factor Authentication: Lock your machines with certificates + security codes
Forget those complicated installation procedures. It takes 30 seconds from start to finish to add Authy Two-Factor Authentication to your SSH.
We know passwords are not safe, we designed Authy SSH to work best with authorized keys.
Someone in your organization doesn't have a smartphone? We got you covered. Authy SSH can send them the token via SMS or a phone call. The rest can install the Authy App for free right to their phones (it even works while your offline).
sudo bash authy-ssh install /usr/local/bin
sudo /usr/local/bin/authy-ssh enable `whoami`
sudo service ssh restart
SCP stopped working
Currently SCP breaks, we're working on a way to fix it
Is there a way to disable SMS?
Yes, if you'd like to disable SMS altogether send us an e-mail to [email protected]. We'll take care of it.
How does Authy SSH works?
We use the forced-command directive to run our plugin when the user is logging in. After we verify the token we return a shell to the user.
You can easily add SSH Two-Factor Authentication to all of your machines in an instant. It works great with chef or puppet.
Certificates can be stolen remotely from your machine, but stealing your physical phone is harder. Two-Factor brings a whole new layer of security to your SSH access.
Authy is simple all the way, from the installation to the mobile app's. We take care of all the little details so you can just relax.
