Enable and debug crossOriginIsolated

Session Information

To mitigate the risk of side-channel attacks, browsers offer an opt-in-based isolated environment called cross-origin isolated. With a cross-origin isolated state, the webpage can use privileged features in a secure way. We'll show why you should adopt crossOriginIsolated and how to implement and test it in Chrome DevTools.

We will walk you through the steps to:

  • Isolate your site using COOP/COEP
  • Test the implementation with DevTools
  • Use a reporting API to verify that your site works correctly for your users
  • Enable powerful features such as SAB / memory measurement
