Windows Authentication

Hi,

I'm building an internet web application with windows authentication enabled. I have configured the web.config file and i have enabled Windows Authentication as well as Anonymous authentication in IIS.

But every time I run the application the browser prompts for userName and password. 

Am i doing it wrong? Is there any way to bypass the login WITHOUTconfiguring anything in the web browser?

I am using MVC 5, C#, IIS 8
