Will quantum-resistant cryptography be standard in all major browsers by 2029?

The countdown to post-quantum encryption adoption

The looming threat of quantum computers breaking classical cryptography has pushed global cybersecurity experts to pursue quantum-resistant algorithms. Standardization bodies are already selecting candidate protocols for widespread use.

Major browsers serve as the gateway to secure online communication, so their adoption signals a new security baseline for the internet. Implementation includes compatibility layers, performance optimizations, and new certificate infrastructures.

My prediction: major browsers will roll out post-quantum options gradually, with full universal adoption by 2029 being possible but dependent on standardized certificate ecosystem readiness.
