OpenVPN, can we combine password+otp in same question ?

supportIconSA

Hello,

My customers use OpenVPN with Flex H and OTP to connect on remote system. It's working fine, but it is tricky to use.
For customer it is very complicate to open web page to send OTP value especially from a mobile device.
Is it possible to add OTP value with password ? like this password + otp value

P.S. We choose OpenVPN because it's working on all system (Windows, Mac, IOS, Android). SecureExtender on Windows can start script after connect to open directly Web page OTP confirmation, but MAC not, and not exist on IOS/Android

Best regards

Hi @supportIconSA ,

Implementing the scenario, you mentioned depends on your RADIUS server and MFA vendor, not the firewall. While we can't provide a complete FAQ since this isn't directly related to our firewall, we can share some relevant resources for your reference:

These resources should give you a better understanding of how to approach this implementation.
