OpenID for Entrepreneurs

  1. 1. OpenID for Entrepreneurs mashup*, 24th April 2007 Simon Willison - http://simonwillison.net/
  2. 2. What is it? • Decentralised single-sign on for the Web • You can reuse one account on multiple sites • ... but you don’t have to cede ownership to a single organisation
  3. 3. Who provides it? • LiveJournal: ~10 million users • AOL: ~65 million users • WordPress.com: ~1 million users • Many more • Digg: coming soon
  4. 4. Who consumes it? • AOL • Ma.gnolia.com - 15% of signups • 37 Signals’ Highrise: 9% of signups • Technorati, for claiming your blog • A growing number of startups
  5. 5. When should you use it? • When you want lots of early adopters to try out your service • When you want to save your users the hassle of maintaining yet another username and password • When you run a site for which people might not be willing to perform full registration
  6. 6. It’s not just SSO... • An OpenID is a URL - a globally unique identifier • Users can build one profile for use on multiple sites • With their permission, you can pull information about them from other services • “Friend import” is a great example
  7. 7. Identity projection • What does it mean for users to be able to project their identity from one service to another?
  8. 8. Some caveats • There is no guarantee that an OpenID isn’t owned by a spammer • An OpenID comes with almost no useful information attached (you can request extra information using simple registration) • You’ll probably still want to use e-mail confirmation, captchas and the like
  9. 9. It’s all about the early adopters • Early adopters are critical to the success of any social website • Early adopters have password pains that aren’t yet affecting the mainstream • When Digg adds support, a link from the homepage will result in thousands of OpenID users flooding to your site
  10. 10. • OpenID is one small piece of the identity puzzle • It’s not OpenID that’s exciting, it’s the things that will be built on top of it
