Of these two, the U2F was significant, as it required biometric identification system manufacturers to store private encryption keys exclusively on the scanning device. It included two main components, the Universal Authentication Framework (UAF) and a Universal 2nd Factor (U2F). You can find more information about the latest release and guide on how to generate hardware security keys with OpenSSH in the release notes. By 2014, the FIDO Alliance published their first specification.
If you are unaware, OpenSSH last year also introduced another security feature that encrypts private keys before storing them into the system memory, protecting it against almost all types of side-channel attacks. Users may consider enabling this option manually."
"A future release of OpenSSH will enable UpdateHostKeys by default to allow the client to automatically migrate to better algorithms. "This algorithm is unfortunately still used widely despite the existence of better alternatives, being the only remaining public-key signature algorithm specified by the original SSH RFCs."
