Please do not top post. One thing: what do you mean "yubikey" in this context? Yubikey (at least 5 which I own) have some "applications" and can act as u2f key or generate codes compatible with google auth (I least I was able to use it as a replacement for google auth). Or you mean its own challenge-response protocol? And if I understand you correctly you should: 1. verify if there are pam modules (at least for u2f and yubico answer is "yes") 2. and probably use substack (http://linux-pam.org/Linux-PAM-html/sag-configuration-file.html) but, honestly I did tested it.
