Cloudflare targets 2029 for full post-quantum security

Cloudflare announces an accelerated post-quantum roadmap targeting full post-quantum security (including authentication) by 2029 in response to recent public research and industry advances suggesting Q-Day could arrive much sooner than prior estimates; the post outlines risks from quantum-capable adversaries (particularly against authentication and long-lived keys), recommends prioritizing migration of long-lived credentials and disabling quantum-vulnerable cryptography where possible, and urges organizations and governments to coordinate and plan for a multi-year migration.
