  • OpenID Connect From: OpenID Type: Page Date: 2014-02-04
  • OpenID Connect 1.0 is a simple identity layer on top of the OAuth 2.0 protocol. It allows Clients to verify the identity of the End-User based on the authentication performed by an Authorization Server, as well as to obtain basic profile information about the End-User in an interoperable and REST-like manner.

  • Frequently Asked Questions From: OpenID Type: Faq Date: 2014-02-20
  • OpenID Connect lets developers authenticate their users across websites and apps without having to own and manage password files. For the app builder, it provides a secure verifiable, answer to the question: “What is the identity of the person currently using the browser or native app that is connected to me?”

  • OpenID Certification Program From: OpenID Type: Page Date: 2015-02-18
  • OpenID Certified markThe OpenID Foundation enables deployments of OpenID Connect and the Financial-grade API (FAPI) Read/Write Profile to be certified to specific conformance profiles to promote interoperability among implementations. The OpenID Foundation’s certification process utilizes self-certification and conformance test suites developed by the Foundation. Certified implementations can use the “OpenID Certified” certification mark.

  • Announcing GAIN: Global Assured Identity Network From: personal By: Nat Sakimura Type: Post Date: 2021-09-14
  • All business entities in the network are vetted as part of the creation and maintenance of their business accounts at their hosting organization, and they cannot remain anonymous. They will be accountable. As a result, the consumer has the assurance that they will be safe to transact with them—meaning more business for the Relying Parties. All of the good actors benefit.

  • DIF and OIDF cooperation From: DIF Type: Post Date: 2020-11-09
  • to work together on areas of mutual interest, allowing working groups to align and coordinate through dual-members. The first major collaboration, which has already been underway for weeks, is a process for revising the Self-Issued OpenID Connect (SIOP) chapter of the OpenID Connect (OIDC) specification

Working Group

  • A/B Connect Working Group From: OpenID Type: Working group Established: 2015-02-18
  • OpenID Connect performs many of the same tasks as OpenID 2.0, but does so in a way that is API-friendly. OpenID Connect can also be extended to include more robust mechanisms for signing and encryption. Integration of OAuth 1.0a and OpenID 2.0 required an extension (called the OpenID/OAuth hybrid); in OpenID Connect, OAuth 2.0 capability is built into the protocol itself.

  • OpenID Connect Client-Initiated Backchannel Authentication Flow – Core 1.0 From: OpenID By: Rodriguez Fernandez Type: Specification Date: 2021-08-01
  • OpenID Connect Client Initiated Backchannel Authentication Flow is an authentication flow like OpenID Connect. However, unlike OpenID Connect, there is direct Relying Party to OpenID Provider communication without redirects through the user’s browser. This specification has the concept of a Consumption Device (on which the user interacts with the Relying Party) and an Authentication Device (on which the user authenticates with the OpenID Provider and grants consent). This specification allows a Relying Party that has an identifier for a user to obtain tokens from the OpenID Provider. The user starts the flow with the Relying Party at the Consumption Device, but authenticates and grants consent on the Authentication Device

  • OpenID Connect for Verifiable Presentations From: OpenID By: Oliver Terbu Type: Specification Date: 2022-01-28
  • This specification defines an extension of OpenID Connect to allow presentation of claims in the form of W3C Verifiable Credentials as part of the protocol flow in addition to claims provided in the id_token and/or via UserInfo responses.

  • Self-Issued OpenID Provider v2 From: OpenID By: Kristina Yasuda Type: Specification Date: 2022-01-28
  • This specification extends OpenID Connect with the concept of a Self-Issued OpenID Provider (Self-Issued OP), an OP which is within the End-User’s local control. End-Users can leverage Self-Issued OPs to authenticate themselves and present claims directly to the RPs. This allows users to interact with RPs directly, without relying on third-party providers or requiring the End-User to operate their own hosted OP infrastructure.

  • OpenID Connect for Identity Assurance 1.0 From: OpenID Type: Specification Date: 2022-08-19
  • This specification defines an extension to OpenID Connect [OpenID] for providing Relying Parties with identity information, i.e., Verified Claims, along with an explicit statement about the verification status of these Claims (what, how, when, according to what rules, using what evidence). This specification is aimed at enabling use cases requiring strong assurance, for example, to comply with regulatory requirements such as Anti-Money Laundering laws or access to health data, risk mitigation, or fraud prevention.

  • OpenID Connect for Identity Assurance – Overview & Call to Action From: OpenID Type: Post Date: 2022-08-25
  • OpenID Connect for Identity Assurance is primarily focussed on addressing use-cases where the details of the assurance process used to verify and validate the end-users identity need to be explicitly communicated.

    The working group believes it’s a good fit for account opening, staff on-boarding, account recovery and access to restricted services where communication of how the underlying identity was established is needed.

  • OpenID Connect Extended Authentication Profile (EAP) ACR Values 1.0 From: OpenID Type: Specification Date: 2021-10-03
  • This specification enables OpenID Connect Relying Parties to request that specific authentication context classes be applied to authentications performed and for OpenID Providers to inform Relying Parties whether these requests were satisfied. Specifically, an authentication context class reference value is defined that requests that phishing-resistant authentication be performed and another is defined that requests that phishing-resistant authentication with a hardware-protected key be performed. These policies can be satisfied, for instance, by using W3C scoped credentials or FIDO authenticators.

  • This session discussed how OIDC Claims Aggregation Draft solves certain problems left open in Connect-Core: 1/ How to get a token from CP is hand-wavy; 2/ No specified method to down scope the userinfo of the CP; 3/ No way to provide a binding information between CP:sub and IdP:sub.

  • The Era of Self-Sovereign Identity From: Chakaray Type: Post Date: 2020-12-01
  • VC-AuthN OIDC uses the OpenID connect standards to easily integrate with the supported systems and also provides a way to authenticate using the verifiable credentials, giving the control back to the user. This is similar to the traditional OpenID connect, the only difference is in the token information. Rather than using the user’s information to construct the token, this uses claims in the verifiable credentials presented by the user.
