Hello,

I was looking at the MFA Providers and it looks like currently only Google authenticator is supported. I need an MFA support but not Google authenticator. Is it possible to write a custom authenticator /MFA connector on UAA that we can then integrate with our TokenValidator? We have our own Authentication server that supports different types of authentication like OTP, grid based, etc and we would like to integrate UAA with that. What would be preferred is that we do the normal username/password authentication on UAA and then for the second factor, instead of using Google Authenticator, we have our custom provider/connector that we can integrate with our token validator/server for authentication. Is it possible to make changes in the UAA code and write a provider to achieve this?
