2-factor authentication with OpenVPN
I'm looking integrate 2-factor authentication using Google authenticator. This can be done on a standalone OpenVPN server, however I like the clean integration of OpenVPN with pfsense. Where can I edit the config files to integrate 2FA with my current OpenVPN setup? On a normal linux server, the command would just simply be:
apt-get -y install openvpn libpam-google-authenticator
use freeradius - set it up there.
i already have a dedicated RADIUS server integrated with Active Directory.
is there still a purpose for freeradius and allow me to do 2FA?
Then setup your 2fa there.. But if you don't want your openvpn integrated with that then sure you could run freerad on pfsense for your openvpn connection.
My RADIUS and AD is running from windows server 2008. There's no Google Authenticator package that can integrate with windows machine as far as i know.
Thanks, I'll look into the freerad package for pfsense. If I do this, will I be able to configure freerad through commandline and use apt-get to install additional packages for the freerad?
