Hi, 
i am working on implementing "Two-Factor Authentication With Duo-Security" in ASP.NET using VB.I have an issue, after primary authentication, the iframe is visible with "Unable to resolve the server's DNS address.".So, i went and changed the value in browser with correct value for src for iframe. Then, iframe shows "Access Denied".

Can you please provide me an example for "Two-Factor Authentication With Duo-Security" in ASP.NET.

Thanks,
Raghu Veena
