it describes how to use your YubiKeys (please always use at least two, so that you have a backup) for GnuPG keys and SSH.
I've been using this setup since 2018 and it is brilliant. I know GnuPG is not in fashion these days, but thanks to this setup I have SSH logins using YubiKeys, encrypted backups using GnuPG, and 2-factor authentication for a number of sites that support Webauthn. All with backup keys, which is IMPORTANT: do not get locked into using a single device, because sooner or later you will lose that device or it will suddenly die.
