I recently installed Ubuntu Wacky Whatever, the latest version, and I’m very excited about it shipping with SSH 8.2, which means that I can finally use hardware USB keys for secure, easy to use authentication. If securing your devices has been something you’ve wanted to easily do yourself, read on, because it’s finally happening.
One of the most exciting security-related developments recently has been the development of WebAuthn and FIDO2, which are basically euphemisms for “nice security stuff”. In summary, WebAuthn and FIDO2 aim to make it really easy to use security devices with stuff by standardizing the way the two talk to each other, and using better terms than “stuff”.
This is great news for us, because now we can have dirt-cheap USB keys that can be used to secure all our authentication very easily, without requiring any special security knowledge. All you need to know to be completely immune to phishing, password theft, and a whole host of other ways of losing Bitcoin is to just plug your USB key in, press the little button/type your PIN/enter your fingerprint, and you’re logged in.
What does this have to do with SSH? Very little, but
