OAuth Gaining Momentum
In typically forthright style, Jeff goes on to highlight why this is such a problem. In short “they have effectively asked for the keys to my house in order to riffle through my address book.”
A number of companies and individuals are working on solutions to this problem including Google, Yahoo and Microsoft, as well as the OAuth project. Initiated by Blaine Cook, Chris Messina, Larry Halff and David Recordon, OAuth aims to provide an open standard for API access delegation. The OAuth discussion group was founded in April 2007 to provide a mechanism for this small group of implementers to write the draft proposal for the protocol. During development significant contributions were received from Eran Hammer-Lahav and Google's DeWitt Clinton. The version 1.0 specification was formally released on December 4th 2007.
At a high level OAuth works as follows:
- Your site has established a relationship with various webmail service providers.
- You share a pass-phrase, or a public key, that you can use to gain access to the web contacts.
- You re-direct the user to the login page for their webmail service provider.
- The user signs in and tells the webmail service provider that is OK for your site to access their address book.
OAuth is already gaining considerable momentum, with implementations for many popular languages including Java, C#, Objective-C, Perl, PHP and Ruby. The majority of these implementations are hosted by the OAuth project via a Google Code repository. Ryan Heaton has implemented OAuth for Spring security which can be found here. Sites supporting OAuth include Twitter, Ma.gnolia and Google (Alpha launch post here).
