WhatsApp on Friday introduced a Web browser extension called Code Verify that lets users check whether the WhatsApp Web version they are using on their system is authenticated. The Web extension automatically verifies the authenticity of the WhatsApp Web code being served to the users and confirms that their messaging experience is secure and not tampered with, the company owned by Meta said. The Code Verify extension has been developed in partnership with Cloudflare, a Web infrastructure and security company. It’s available as an open-source project to let other companies, groups, and individuals integrate the same experience for their apps. Open-sourcing will also help receive contributions from developers around the world to improve the extension over time.
Available for download on Chrome, Firefox, and Edge, the Code Verify extension checks for the resources on the entire webpage to verify the authenticity of the code when you open WhatsApp Web on your mobile or desktop browser.
Once the code is verified by the extension, it notifies users whether the Web client they are using is authenticated.
The Code Verify extension runs automatically when you use WhatsApp Web on your browser. It shows a checkmark in a green circle when it is pinned to the toolbar of your browser to reflect that the code of your WhatsApp Web has been fully validated.
In case the extension is unable to validate the code that has been served to you on the Web client of the messaging app, you will get three distinct messages — depending on the issue.
- Network Timed Out: If your page can’t be validated because your network has timed out, your Code Verify extension will display an orange circle with a question mark.
- Possible Risk Detected: If one or more of your extensions is interfering with its ability to verify the page, your Code Verify extension will display an orange circle with a question mark.
- Validation Failure: If the extension detects that the code you’re using to run WhatsApp Web is not the same as the code everyone else is using, the Code Verify icon will turn red and show an exclamation mark.
You can see more information about the validation by clicking on the Code Verify extension icon in your toolbar when it is green, orange, or red.

You can also download the source code if you want to investigate the issue further or get it verified by an agency.
