This sounds interesting will read up on it.

https://keybase.io/ this keybase? It seems to be a chat and file sharing thing, irc didn’t it used to be an identity based things years ago?

Tailscale sounds like an interesting solution, I already have wireguard vpn which runs on all my personal devices.

At the moment github is my single source of truth for pub keys so having that setup might work, I could also automate the cronjob via ansible when I setup default config on new vms

This is an interesting solution, I don’t have LDAP running at the moment but it’s on my list of things to add to my setup.

I guess it’s just the way I’ve been using it for years and years. I’ve been remote working for abour a decade so I’ve been in places where it could have been possible to grab my keys if I’d left a laptop unlocked, not likely though.
