==== Implement support for Make Multi-Factor Authentication in for OpenVPN a first class citizen ====

Mozilla uses OpenVPN with MFA via deferred C plugins and pythons scripts. However, there are several caveats that require non-plugin based modifications, such as One Time Passwords (OTP) client input and session tracking. The goal of this project is to research and implement provide a reliable first class user experience when using MFA support in with OpenVPN, and contribute it to the Open Source OpenVPN project.
