With the increasing use of WhatsApp Web, ensuring its authenticity has become more important than ever. Cybersecurity threats and phishing attempts are on the rise, and users need a reliable way to confirm they’re using the official, unaltered version of WhatsApp Web. That’s where Code Verify, a browser extension developed by Meta (WhatsApp’s parent company), comes into play.
Code Verify is a free, open-source browser extension created by Meta in partnership with Cloudflare. It verifies in real time that the WhatsApp Web code running in your browser hasn’t been tampered with or modified by third parties.
