Facebook Launches OpenID Support – Users Can Now Login With Gmail Accounts

Last month, Facebook announced that users would soon be able to login to the site via OpenID. Today, Facebook has officially become an OpenID relying party: users can now register for Facebook using their Gmail accounts and any OpenID provider that supports automatic login. As such, Facebook has become the largest OpenID relying party on the web.

Now, once users link their Facebook account to a Gmail address (or OpenID URL), they’ll be automatically logged in when they go to Facebook after having logged into that service. Facebook says that in its user testing so far, users who register through OpenID actually get engaged with Facebook more quickly than others.

“In tests we’ve run, we’ve noticed that first-time users who register on the site with OpenID are more likely to become active Facebook users. They get up and running after registering even faster than before, find their friends easily, and quickly engage on the site. We’ll continue to integrate more OpenID providers into our registration and account linking flows as they support automatic login,” Facebook says.

To link an existing account with a Google or OpenID account, users can go to their Account Settings page and choose an account in the Linked Accounts section. Yahoo and MySpace are also listed here, but a Facebook prompt says “Note that your accounts from Myspace and Yahoo do not allow for automatic login.”

We recently spoke with Facebook engineer Luke Shepard, who represents Facebook on the OpenID Foundation board, to get his perspective on Facebook’s OpenID integration.

Inside Facebook: Luke, why is Facebook integrating OpenID support?

Luke Shepard: The primary motivation for us is to accept OpenID for new users registering for Facebook. For now, that means through Gmail, though more providers will be coming soon. Google released their address book API a few months ago through OpenID, and we’re using that. The response has been pretty positive so far in our user testing.

In addition, for existing users, we’re offering a feature for you to login automatically if you have an account with an OpenID provider. For example, I have a Gmail account. Every day, I open up my browser and go to Gmail and Facebook, and now you can be automatically logged into Facebook after logging into Gmail.

Which other companies have support coming soon?

Yahoo has been an OpenID provider for over a year and is on the verge of supporting automatic login. Microsoft hasn’t launched as a provider yet, but will sometime. The big three will be covered pretty soon.

What steps did Facebook take to overcome some of the user experience challenges that have hindered OpenID?

One thing we did was we skipped some of the hard part. Probably the most difficult open question in the OpenID community is how do you get a user to register with an OpenID for the first time. We’re skipping that for existing users right now to make sure we get the underlying system working. We’re working on a lot of ideas for how we can present that to the user after we launch – like how to do OpenID login in a popup and keeping users on the page versus sending them off to another site.

We’re a major identity provider with the Facebook Platform and Facebook Connect. We’ve been trying to do a good job on this for apps, and this is a good chance for us to eat our own dogfood with identity and learn what we can do better for apps in the future.

There are very few sites that support the background automatic login in OpenID, but this is a core part of the Facebook Connect experience. Others haven’t done this yet because it’s pretty difficult technically. When designing our OpenID implementation, I was drawing on several Facebook engineers here to learn from how we did various things with Connect. It’s also still rapidly evolving.
