Minutes of the F2F 68 Meeting in Vienna, Austria - SCWG, September 23, 2026
September 23, 2026 by Wayne ThayerMinutes of the CA/Browser Forum Face-to-Face Meeting 68 Server Certificate Working Group, September 23, 2026Call to Order and Administrative Business Presiding: Dimitris Zacharopoulos (HARICA), SCWG Chair, with Wayne Thayer (Fastly) Agenda: No changes or additions were proposed; the agenda as circulated was approved. Approval of minutes: The minutes of the August 27 and September 10 teleconferences were each approved without objection, for publication. Membership — Huawei (Certificate Consumer applicant): Huawei’s application to join as a Certificate Consumer had been discussed at a prior teleconference, where the Forum had requested clarification from Huawei. Dimitris reported that Huawei’s responses had been circulated to the list and, in his view, adequately addressed the earlier concerns. There were no objections, online or in the room, and Huawei’s application as a Certificate Consumer was approved. Dustin Hollenback (Apple) asked whether the candidate-review process itself had been formalized following earlier feedback. Dimitris said he and Wayne Thayer would work on streamlining this process, likely in consultation with other working group chairs, since the same candidate-intake process applies across working groups. A candidate-information chart previously put together by Ryan Dickson (Google Chrome) was suggested as a starting point, along with including the list of standard clarifying questions (previously produced by Aaron Gable) on the wiki alongside the IPR agreement, so future candidates and reviewers have a consistent reference. Wayne Thayer was asked to post this material to the wiki. Membership MicroSec probationary-to-voting status: The chair noted that a member admitted earlier as a probationary member has now satisfied the attendance requirement for voting membership by participating in this Face-to-Face meeting, and the necessary status change would be made. Chair’s Report: Updates Since the Last Face-to-Face Presenter: Dimitris Zacharopoulos (HARICA)
