SK SSH Agent

The SK SSH Agent is a utility that allows you to use FIDO/U2F security keys with PuTTY and OpenSSH. FIDO/U2F keys are a new generation of hardware keys that offer a higher level of security than traditional passwords.

To use the SK SSH Agent, you will first need to install PuTTY and OpenSSH. You can then generate a FIDO/U2F security key using the SK SSH Agent. Once you have the security key, you can add it to PuTTY or OpenSSH.

Once you have added the security key to PuTTY or OpenSSH, you will be able to use it to log in to the servers. When you log in to the server, you will be prompted to enter the code from your FIDO/U2F security key. After entering the code, you will be logged in to the server.
