Cloudflare has introduced support for Privacy Pass, a privacy-preserving protocol developed in collaboration with researchers from Royal Holloway and the University of Waterloo. The protocol leverages zero-knowledge proofs to enable anonymous access across multiple sites without enabling tracking. Users can now use the Privacy Pass browser extension to reduce the number of challenge pages presented by Cloudflare, improving the browsing experience for some of the Internet's least privileged users. The Privacy Pass extension is available for both Chrome and Firefox.
