Pfa Zygma’s considered responses to the draft 63A rev.4 criteria. In the interests of transparency I am providing these to those once associated with the IAWG. I’m not asking anyone to do anything with these comments, I just want to ensure that they are available for reference purposes to the widest audience. Recipients are free to do with them as they wish. Kind regards, Richard G.

We invite you to review the attached documents and provide your feedback. Please review each tab in the file and share any feedback. There is no need to focus on cross-referencing at this stage; that work will be completed for the final publication. This draft covers only Volume 63A – Identity Proofing. Drafts for 63B and 63C will be released next, in that order. You may submit feedback immediately using the attached comment form. The draft criteria will be publicly released in the first week of December, with the public comment period ending by 20 January 2026. Please ensure your feedback is submitted before that date. All comments must be sent to feedback@kantarainitiative.org. Submissions sent elsewhere may not be received in a timely manner. If you have questions or require clarification, please contact us at feedback@kantarainitiative.org. Your participation is essential in ensuring that the criteria remain accurate, complete, and fully aligned with the NIST Digital Identity Guidelines. Thank you for your continued engagement and contribution to the Kantara community.
