Cloudflare targets 2029 for full post-quantum security (blog.cloudflare.com)

Cloudflare says it is accelerating its post-quantum cryptography program and now targets 2029 for full post-quantum security across its products, including upgrading post-quantum authentication. The post cites recent quantum-related advances and argues that authentication is the most urgent gap because “Q-Day” would make quantum-forged credentials an immediate, catastrophic risk. Cloudflare also highlights the need to prioritize long-lived cryptographic keys, prevent downgrade attacks (e.g., PQ HSTS/certificate transparency), and rotate dependent secrets—work it expects to take years rather than months.
