Two Factor Authentication (MFA)
What plugin or app do you recommend for multi factor authentication that I can install in my pfsense and have my users have another authentication maybe like google authenticator or something like that.
Right now I use Pfsense with Radius on a windows server but Im open to hear about any MFA for protect my users.
Thanks in advance.
I use DUO Mobile (https://duo.com) and it works very well for our VPN users. Everytime a users tries to login, they will get a push notification to their phone which they have to allow before they can login. If your already using radius as the authentication server, you can implement the DUO radius proxy to send the push. Their service is free up to 10 users so I'd give it a try and see how you like it. I have been very happy overall.
