Best OpenId API for ASP.NET MVC application

2118

+25 Q:

I am developing an ASP.NET MVC application and I want to use OpenId.

What is the best option?

Does anyone know what StackOverflow uses? Is the Login UI custom-developed, or provided by an API/service?

+23 A:

We use the excellent DotNetOpenId library here on Stack Overflow:

http://code.google.com/p/dotnetopenid/

Our original login UI was provided by ID Selector, but we've since rolled our own minimalist version.

Well, looks like we need to upgrade our ID Selector to RPX!

Jarrod Dixon 2009-02-09 01:45:39

Yes looks like it. Let us know how it goes.

-1 on RPXNow. http://blog.nerdbank.net/2009/01/why-using-rpxnow-is-bad-idea.html

openid-selector is cool!

I'm actually about to migrate from RPX back to openid-selector. The RPX servers are down about 5% of the time that someone tries to register.

Would you modify your answer, nearly a year on? Does this information still hold true today?

I'll second the recommendation for DotNetOpenId and add a recommendation for openid-selector (open source version of idselector)

Thanks! Just tried it, Exellent compaird to the idselector.com's. Specially if you do need to change the look or language :P

Why is DotNetOpenID so huge??? Is there a source code available?

Andy 2010-06-01 17:33:47

Because it was the first. I believe there are better alternatives now, but I don't know what they are. I use RPXnow whenever possible.
