Freeradius 2FA

Hi guys, go a question - Is it possible to use freeradius with some 2FA somehow? Most perfect scenario would be: - try to log in on remote hosts, - remote server communicates with freeradius, - radius gives a question to some phone 2FA app, - then we get click "ALLOW" on the mobile 2FA app, - tadam we are logged in, -- Jarosław Kłopotek, kom. 607 893 111 INTERDUO Bujek Kłopotek Sowa sp.j. ul.
