OpenVPN Support Forum

I have an OpenVPN server setup in OPNSense that include TOTP two-factor authentication. Where do I put the two-factor code in the OpenVPN Connect client?

I don't see anywhere to enter it and when I try to connect it doesn't bring up a prompt or anything - it just says "Authentication Failed".

Hello VECCTOR,

Most likely the authentication fails before you even get to the MFA. Once username/password authentication succeeds, then MFA should be requested. If username/password already fails, you may not even get an MFA request.

Kind regards,
Johan

I have the same problem. If my method for MFA is a code to enter, where do I put it? If my method is approving by authenticator or with phone call and pressing # to approve, it works fine. I need options for entering code? I am using Microsoft NPS setup with OpenVPN (PFSense)

Same problem here with just about any daemon-based OpenVPN client. There simply doesn't seem to be a way to pass in static-challenge response to a daemon-based client.
