Quick and dirty setup guide for Google Auth 2FA on CentOS7
## Build RPM as per
# Do this elsewhere, you don't want dev tools on a box you're trying to secure.  ;) 
# Also note, the repo has moved, so you need to adjust the git path:

sudo yum install epel-release -y
sudo yum install qrencode qrencode-devel qrencode-libs
sudo yum install google-authenticator-1.03-1.el7.centos.x86_64.rpm
