From Fedora Project Wiki


Fedora infrastructure has setup to use two factor authenication for all 'sudo' access on any machines. Setting up two factor authentication for this will also require it for all logins using the fedora account system.


You need to know about this if you are in a FAS group that provides you shell access to any infrastructure machines, and additionally you have permissions / need to sudo on those machines.
