Last time I looked at google authenticator is was OAUTH-only so the only way to do it was run a cleartext protocol, steal the user's password, and then pretend to be a web browser. Maybe things have changed since. Authy had this but it is obsolete: https://github.com/twilio/authy-freeradius They've replaced their authy API with the new "verify" API. It's a REST API so there is no insane poorly coded RADIUS relay agent involved as with some other services, but as far as I can google they are not providing pre-worked FreeRADIUS modules or scripts anymore. ________________________________________ From: Freeradius-Users <freeradius-users-bounces+bjulin=clarku.edu@lists.freeradius.org> on behalf of Fernando Patzlaff <patzlaff@gmail.com> Sent: Friday, May 7, 2021 1:17 PM To: freeradius-users@lists.freeradius.org Subject: [EXT] FreeRadis 2FA - 2 Factor Authentication Hello!
