Should I use the built-in membership provider for an ASP .NET MVC application?

Question

I've been using a custom membership provider for authentication in all my web form applications till now. I'm about to start developing my first website using MVC. I'm wondering if I should I use the built-in membership provider that ships with ASP .NET MVC, or if I should create my own. My site needs to integrate with openid, facebook, google etc for authentication and openauth for api access. I'm wondering how easy it would be to use the built-in one for my needs.

Personally, I hate using the ASP.NET Membership provider that's available in the core framework ... when it persists to a SQL SERVER database. All the tables and views are such an overkill for a single website. For a hosting company? .. maybe ... but for all the enterprise sites I've done .. it's been such a fraking overkill and hassle. As to the actual provider interface, etc ... it's very good .. but still very hardcore, etc. An overkill for simple-medium sites, IMO.

So personally, I would use some simple custom code to handle membership persistence for most basic-medium websites.

This then segues to your second question: OpenId. Use Andrew Arnott's DotNetOpenAuth .NET framework -> it litterally Kicks Serious Ass (tm). Using this is independent of HOW you save the user membership data to a repository. Ie. if you go ahead and use the Sql Server + ASP.NET Membership provider, you can still (and should) use DotNetOpenAuth. If you have a simple, custom way to save user details to a database (which is what I do), you can also still use DotNetOpenAuth -- the two are independent of each other.

So, IMO, don't use the overcomplicated ASP.NET Membership + Sql Server stuff but a simple table or two to save your own user details. Next, you MUST use DotNetOpenAuth for any OpenId stuff (StackOverflow uses DotNetOpenAuth to handle their OpenId login).

Good Luck :)

(I'm sure my opnions of the ASP.NET Membership provider + Sql Server to persist that info will cause a few people to nerd-rage, here).

If you have to ask, you shouldn't be writing your own provider. Doing security well is really hard. Doing it wrong is incredibly easy.

But the good news is that what you want is incredibly common, and there are tested, off-the-shelf tools which already do it. An example is Janrain. There are others, too. Use an existing, proven tool whenever possible.
