WebAuthn is a standard API to request and process public key challenges for authentication.
The standard consists of the World Wide Web Consortium’s (W3C) Web Authentication (WebAuthn) and the FIDO Alliance’s Client-to-Authenticator Protocol (CTAP). The FIDO Alliance hopes to eventually get rid of passwords altogether and instead provide procedures to authenticate users securely through multiple factors but without the need for passwords. FIDO2, U2F and the FIDO AllianceįIDO2 is a collection of standards maintained by the FIDO Alliance. This is especially true for password-less logins using a FIDO2 protocol. Should you lose a key, you’ll want to use your second key to sign in on every service the keys are registered with, remove the lost key, and register a new one. In practice this means you will need to register both hardware tokens with your Linux and web accounts, generate OpenSSH private keys twice, and upload both OpenSSH public keys to the servers and services you use (for example, GitHub). Consequently, all registrations you make with your primary key you should immediately repeat with a second backup key that you will store in a secure location, maybe even a safe. As hardware security tokens are unique and designed to be extremely hard to copy you cannot just make a backup of it like you can with software vaults like KeePass or AndOTP.
Keep a backup security keyĪs soon as you start working with security tokens you have to account for the potential to lock yourself out of accounts tied to these tokens. This post will not cover storing OpenPGP keys or X.509 certificates because those features are hardware dependent and not part of the FIDO U2F standard.
