Cloudflare now supports security keys with Web Authentication (WebAuthn)!

What this post added

This post introduces support for security keys as a two-factor authentication (2FA) method for Cloudflare user accounts, leveraging the Web Authentication (WebAuthn) protocol. It explains the WebAuthn protocol, its advantages over other 2FA methods (resistance to SIM swapping, phishing, and ease of use), and its privacy guarantees. The implementation allows users to register hardware security keys or use built-in biometrics for authentication.
