If you hear privacy and your first thought is laborious processes and access management, this interview may be just as mind-expanding for you as it was for our host Pascal. He is joined by Alex and Haozhi who talk about the Anonymous Credential Service (ACS), a highly available multitenant service that allows clients to authenticate in a de-identified manner. They discuss the cryptographic primitives powering the service and the various challenges they encountered scaling it to support Meta's products.
