What is quantum-safe encryption — and do you need to worry?

Cloudflare will start issuing quantum-safe TLS certificates, upgrading website encryption ahead of a future quantum threat. You do not need to do anything but keep devices updated.

Cloudflare says it will begin issuing quantum-safe TLS certificates — the digital credentials that keep your connection to websites private and trustworthy. Here is the plain-English reason this matters: the encryption protecting your browsing today is strong against every classic computer, but a powerful-enough quantum computer could one day crack it wide open. Rather than waiting for that day to arrive, the industry is ‘replacing the locks ahead of time’ with new algorithms designed to resist quantum attacks.

You do not need to do anything: no settings to change, no services to buy. Keep your browser, phone, and computer updated — and the protection simply arrives with those updates.
