What Is Code Verify?

Code Verify is a specialized security utility by Meta Platforms, Inc. that introduces 'Web Binary Transparency' to the web. It ensures that the JavaScript code running in a user's browser for Meta's platforms (WhatsApp, Instagram, etc.) matches the official, untampered version. By partnering with Cloudflare for independent verification and open-sourcing the extension, Meta aims to build trust with security-conscious users who are wary of web-based session vulnerabilities.
