title: Integrating Facebook Authentication with existing ASP.NET Membership
body: <p>Coding Platform: ASP.NET 4.0 WebForms with C#  </p>
  
  <p>We have a website with the existing login details managed by ASP.NET Membership Provider.<br>
  Now client wants to add Facebook Connect to it.  </p>
  
  <p>So on registration I am giving a Register using Facebook Button.<br>
  How shall I proceed with integrating a successful authentication from facebook to my membership provider?  </p>
  
  <p>What I am planning is to create a username with unique identifier as a new user in ASP.NET Membership and link that to another table that contains other open-id users(cos in future we plan to extend to Google, Twitter, Live and all). Is that the best method?</p>
