Overview

How to configure FreeBSD and applicable applications to work with Yubikey for authentication. This serves as my work-in-progress documentation of the configuration knobs needed to make this work properly.

FreeBSD ssh with piv smartcard slot on Yubikey (pkcs11 via libykcs11.so)
FreeBSD ssh with fido support on Yubikey
FreeBSD Firefox/Chromium with fido + webauthn support on Yubikey
FreeBSD local console and gdm authentication using pam on Yubikey
FreeBSD official YubiKey tools

Think twice before abandoning Xorg. Wayland breaks everything!

Hence, if you are interested in existing applications to "just work" without the need for adjustments, then you may be better off avoiding Wayland.

Wayland solves no issues I have but breaks almost everything I need. Even the most basic, most simple things (like xkill) - in this case with no obvious replacement. And usually it stays broken, because the Wayland folks mostly seem to care about Automotive, Gnome, maybe KDE - and alienating everyone else (e.g., people using just an X11 window manager or something like GNUstep) in the process.

As 2024 is winding down:

	#include <future>
	#include <iostream>

	using namespace std;

	future<int> async_add(int a, int b)
	{
	auto fut = std::async([=]() {
	int c = a + b;
	return c;
