I need authentication advice for an ASP.NET MVC 3 application

I have a web applicati开发者_如何学运维on that will be used by the public. This application has a login credentials requirement.

I don't want to create yet another site that you have to create a custom username/password combination unless you really want too. I would like to support 3rd party logins like Facebook, Twitter, etc...

In the end this website could run in the Azure cloud as well so I am open to anything special to that.

One thing to note is the Microsoft Membership Provider that is part of ASP.NET is a great way to have custom login/passwords with a nice integration into MVC code. What I would love is that Provider opened up to allow 3rd party logins.

Does anyone have any recommended solutions that they have had good success with?

Look into using OpenID like StackOverflow does. I have had good success using DotNetOpenAuth.
