Formed in 2009, the Archive Team (not to be confused with the archive.org Archive-It Team) is a rogue archivist collective dedicated to saving copies of rapidly dying or deleted websites for the sake of history and digital heritage. The group is 100% composed of volunteers and interested parties, and has expanded into a large amount of related projects for saving online and digital history.
You can now authenticate to SSH using a FIDO2 security key by adding a sk-ecdsa-sha2-nistp256@openssh.com or sk-ssh-ed25519@openssh.com SSH key to your account. SSH security keys store secret key material on a separate hardware device that requires verification, such as a tap, to operate.
This combination of storing the key on separate hardware and requiring physical interaction for your SSH key offers additional security. Since the key is stored on hardware and is non-extractable, it can't be read or stolen by software running on the computer. Additionally, the tap prevents unauthorized use of the key since the security key will not operate until you physically interact with it.
