Brown, who spearheaded the development of webauthn-rs — an open-source Rust library for implementing the WebAuthn standard — warns that the original vision of an open and accessible technology is being compromised.

Over 150 platforms now support passkeys, including major names like WhatsApp, X (Twitter), TikTok, PlayStation, PayPal, Microsoft, Google, Apple, and Amazon.
