Cloudflare's post says Privacy Pass has been deployed for 10 years in systems such as iCloud Private Relay and Privacy Gateway, issuing unlinkable tokens for privacy-preserving rate limiting. It still relies on classical RSA and elliptic-curve cryptography, so a quantum attacker could forge tokens and bypass rate limits, while token redemption remains unconditionally unlinkable. Cloudflare says it is working on next-generation private authentication for agentic traffic and a more open ecosystem, but the excerpt cuts off before the post-quantum replacement details.

Why: For builders using Privacy Pass-style tokens for abuse control, the concrete split is that privacy remains unconditional post-quantum but token forgery does not; any quantum-migration checklist for rate limiting must cover token issuance/signature algorithms, not just linkability. No Malaysia-specific impact is stated in the text.
