John Goerzen’s detailed guide explains how to securely use modern FIDO2/U2F hardware security keys—such as YubiKey, Nitrokey, or Titan—for SSH authentication with OpenSSH. By using non-resident keypairs, these keys make it impossible to extract or misuse private keys, even if a machine is compromised. The article outlines how to generate and manage such keys, the benefits of touch and optional PIN verification, and how to use them safely with ssh-agent and forwarding. Goerzen also warns against insecure practices found in many online guides and offers practical advice for using multiple keys and hosts, configuring PINs, and integrating SSH security into real-world workflows.

In the world of modern portable devices, it may be hard to believe that merely a few decades ago the most convenient way to keep track of time was a mechanical watch. Unlike their quartz and smart siblings, mechanical watches can run without using any batteries or other electronic components.
