First Public Review Period for OpenID Connect SIOPV2 and OIDC4VP Specifications Started


The OpenID Connect Working Group recommends approval of the following specifications as OpenID Implementer’s Drafts:

These would be the first Implementer’s Drafts of these specifications.

An Implementer’s Draft is a stable version of a specification providing intellectual property protections to implementers of the specification. This note starts the 45-day public review period for the specification drafts in accordance with the OpenID Foundation IPR policies and procedures. Unless issues are identified during the review that the working group believes must be addressed by revising the drafts, this review period will be followed by a seven-day voting period during which OpenID Foundation members will vote on whether to approve these drafts as an OpeID Implementer’s Drafts. For the convenience of members, voting will actually begin a week before the start of the official voting period.

The relevant dates are:

  • Implementer’s Drafts public review period: Friday, December 17, 2021 to Monday, January 31, 2022 (45 days)
  • Implementer’s Drafts vote announcement: Tuesday, January 18, 2022
  • Implementer’s Drafts voting period: Tuesday, February 1, 2022 to Tuesday, February 8, 2022 *

* Note: Early voting before the start of the formal voting period will be allowed.

The OpenID Connect working group page is https://openid.net/wg/connect/. Information on joining the OpenID Foundation can be found at https://openid.net/foundation/members/registration. If you’re not a current OpenID Foundation member, please consider joining to participate in the approval vote.

You can send feedback on the specifications in a way that enables the working group to act upon it by (1) signing the contribution agreement at https://openid.net/intellectual-property/ to join the working group (please specify that you are joining the “AB/Connect” working group on your contribution agreement), (2) joining the working group mailing list at https://lists.openid.net/mailman/listinfo/openid-specs-ab, and (3) sending your feedback to the list.


Note that on January 28, 2022 updated versions of both specifications were published that addressed editorial issues identified during the review period. Please review these instead of the original drafts referenced above. The updated drafts are openid-connect-self-issued-v2-1_0-07 and openid-connect-4-verifiable-presentations-1_0-08.
