Subject: 2way authentication for SSH?
Hi,
Does anyone know of a stable / working "2way authentication" system for
SSH, and even web authentication services?
Most of the banks in South Africa have a system that, when you want to make
a payment, they send you an SMS and you need to verify the action with a
secret code which was SMS'd to you. gmail also has this.
Does anyone know of a "universal" plugin / application that can be used
with SSH and even websites like Wordpress / Joolma / Webmin / etc?
Any pointer would be appreciated.

Is it really 2way (as in mutual) authentication or 2factor authentication?
Mutual authentication is normally done with ssl (server + client) certificates.
Most http engines (apache, tomcat) do support them.
For two factor (have, know) authentication "some assembly" is required, at least for openssh.
See: http://roumenpetrov.info/openssh/
Generally speaking, you _do_ want a trusted third party (like a CA) and certainly _not_ another additional unreliable man-in-the-middle. I mean: like google. But should I trust them with regards to security and availability???
