Public Review Period for Proposed Final OpenID Connect Client-Initiated Backchannel Authentication (CIBA) Core Specification

Published June 7, 2021

The OpenID MODRNA Working Group recommends approval of the following specification as an OpenID Final Specification:

A Final Specification provides intellectual property protections to implementers of the specification and is not subject to further revision. This note starts the 60-day public review period for the specification draft 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 draft, this review period will be followed by a seven-day voting period during which OpenID Foundation members will vote on whether to approve this draft as an OpenID Final Specification. For the convenience of members, voting will actually begin a week before the start of the official voting period, for members who have completed their reviews by then.

The relevant dates are:

  • Final Specification public review period: Monday, June 7, 2021 to Friday, August 6, 2021 (60 days)
  • Final Specification vote announcement: Saturday, July 24, 2021
  • Final Specification voting period: Saturday, August 7, 2021 to Saturday, August 14, 2021 (7 days)*

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