Setting up yubikey/solo2 for piv, fido, and gpg on FreeBSD (Firefox, Chromium, PAM, SSH, and GnuPG)

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

Latest Tested FreeBSD versions

  • FreeBSD 13.2 Testing (Aug 2023)
  • FreeBSD stable/13 Testing (Aug 2023) with OpenSSH_9.3p2

This Liquid loop for Jekyll sorts a collection by date in reverse order
{% comment %}
*
* This loop loops through a collection called `collection_name`
* and sorts it by the front matter variable `date` and than filters
* the collection with `reverse` in reverse order
*
* To make it work you first have to assign the data to a new string
* called `sorted`.
