OpenID Connect Specifications are Final!

OpenID logoThe OpenID Connect Core, OpenID Connect Discovery, OpenID Connect Dynamic Registration, and OAuth 2.0 Multiple Response Types specifications are now final! These are the result of almost four years of intensive work, both by specification writers including myself, and importantly, by developers who built, deployed, and interop tested these specifications throughout their development, significantly improving the quality of both the specs and their implementations as a result.

Throughout the development of OpenID Connect, we applied the design philosophy “keep simple things simple”. While being simple, OpenID Connect is also flexible enough to enable more complex things to be done, when necessary, such as encrypting claims, but this flexibility doesn’t come at the cost of keeping simple things simple. Its simplicity is intended to make it much easier for deployers to adopt than previous identity protocols. For instance, it uses straightforward JSON/REST data structures and messages, rather than XML/SOAP or ASN.1.

I want to take this opportunity to thank several key individuals without whose enthusiastic participation and expertise OpenID Connect wouldn’t have come into being. Nat Sakimura and John Bradley were there every step of the way, both motivating the features included and providing their insights into how to make the result both highly secure and very usable. Breno de Medeiros and Chuck Mortimore were also key contributors, bringing their practical insights informed by their implementation and deployment experiences throughout the process. I want to acknowledge Don Thibeau’s leadership, foresight, wisdom, and perseverance in leading the OpenID Foundation throughout this effort, bringing us to the point where today’s completed specifications are a reality. Numerous people at Microsoft deserve credit for believing in and supporting my work on OpenID Connect. And finally, I’d like to thank all the developers who built OpenID Connect code, told us what they liked and didn’t, and verified that what was specified would actually work well for them in practice.

Of course, final specifications are really just the beginning of the next journey. I look forward to seeing how people will use them to provide the Internet’s missing identity layer, making people’s online experiences, both on the Web and on their devices, easier, safer, and more satisfying!
