Facebook First Big Site To Really Embrace OpenID

Apparently it’s embrace the developer community day at Facebook. In addition to the news that they are making activity stream data available to third party developers, they’ll also be making an announcement around OpenID, we’ve heard. And importantly, the announcement is that they’ll become what’s called a relying party, meaning anyone with an OpenID (Yahoo, Google, AOL, MySpace are all issuers, and Microsoft is in beta) can create and log into a Facebook account using those credentials.

Let me take a step back. OpenID is a distributed single sign on solution that allows people to sign into different services with the same login credentials. There are two ways companies/websites can participate in the OpenID framework – as “issuing parties” or as “relying parties.” Issuing parties make their user accounts OpenID compatible. Relying parties are websites that allow users to sign into their sites with credentials from Issuing parties. Of course, sites can also be both. In fact, if they aren’t both it can be confusing and isn’t a good user experience.

All the big guys are now Issuing Parties, which allow their users logging in all over the Internet with those credentials. But none of them accept IDs from anywhere else, so anyone that uses their services has to create new credentials with them. It’s all gain, no pain. There are two exceptions – AOL Mapquest and Google’s Blogger – but for the most part the big guys are issuers, not relying parties. And that has led us in the past to accuse them of exploiting OpenID for their own benefit without giving back to the community. See our post Is OpenID Being Exploited By The Big Internet Companies?

Facebook has been a wild card with OpenID. They’ve talked about adopting it eventually, but their Facebook Connect product has actually muddled the situation – Facebook actually competes directly with OpenID when allowing users to sign in to third party sites via Facebook Connect.

Now that’s going to change, and we’ll soon see users have the ability to sign in to Facebook using, say, their MySpace credentials if they choose to. I like the thought of that.

But it still may be a while before we see the other major players take similar steps. Facebook has never really had notion of a user ID – you’ve always logged in with your Email address, which could have come from any number of other services, so Facebook isn’t really sacrificing much here. Instead of a user name, Facebook members are assigned a meaningless user ID number (though they’re experimenting with vanity pages).

Contrast that with Yahoo and Google, both of which have built up their own login systems, which can be used across multiple services using a single persistent account name. Users benefit because they can seamlessly jump between services, and Yahoo and Google get their users to stay within their own suite of products. There’s a good chance they’re not going to give that up so readily.
