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

Okta Verify TOTP secret key can be extracted easily using curl and the code below.
  1. Get the content of the QR for Okta Verify app setup. It looks like this: oktaverify://[email protected]/?t=XXXXX&f=YYYYY&s=https://DOMAIN.okta.com&issuer=DOMAIN.okta.com&isIdxEnabled=true
  2. Replace XXXXX, YYYYY and DOMAIN to your values in curl below:
curl --request POST \
  --url https://DOMAIN.okta.com/idp/authenticators \
  --header 'Accept: application/json; charset=UTF-8' \
