I have a VM with Ubuntu 16.04.1 on it dedicated to be a 2 factor authentication server for Horizon View. It is attached to my windows domain, and users login via SSH to activate their 2 FA. I would love to know how many of my users have done so as 2 FA is not yet required to login, but will be soon. I'd like to find out either by checking if they've logged in before to Ubuntu, or if there's a list from Google Authenticator I could pull.
Thanks!
