Notes from my journey to getting Yubikey to authenticate everything on my system.

U2F for login and sudo access

I followed this guide: https://support.yubico.com/s/article/Ubuntu-Linux-login-guide-U2F

For step 3, I only did the user-specific pamu2fcfg setup; I did not put it at the system level. This makes the $HOME partition portable, and allows different users on the system to require U2F and/or use different keys.
