I am using PuTTY to access my server via SSH. Due to the complexity of my private key's password, however, I've decided to consider using other methods of authentication, such as biometrics, more specifically fingerprints.
I have looked up how to do such a thing, but it seems that nobody has ever figured out how to do it before. Since I am using Windows 7, there is some integration between the fingerprint scanner's driver and Windows itself (Windows accepts fingerprints as an official method of authentication).
What I would like to do is unlock my laptop's SSH private key by supplying my fingerprint, and the unlocked private key can then be passed on to the server via SSH to log me in (as usual).
The fingerprint program I am using allows me to save passwords for sites, but it is an abandoned program from AuthenTec. It is also the only program that my fingerprint driver (also from AuthenTec) supports.
How can I complete such an undertaking? Or is it simply not worth the effort?
