Edge leverages the Windows Notification API platform to pass the notification from the webpage to the Notification platform which will then render and manage notification in a consistent way across all Windows Apps.
Permission and Management for Microsoft Edge Notifications
Permission and its management function exactly as Chrome, Firefox and Safari. Users visiting the site are prompted for Subscription.

Once the user grants permission, web push notifications can be pushed to the user. These permissions can be managed directly from the parent domain site.
These push notifications can be managed using the Microsoft Action Center. Edge now also supports push notifications on Android.
What Happens Next?
- Additional features to further improve user control and notification fidelity, along with group notifications in the Action Center based on the website domains, to preserve the original context of each notification. [Only for Windows 10 Users]
- Changes in the optimum durations for any notification staying saved in the Action Centre.
- Prototype support for Service Workers and Push API in the EdgeHTML platform. This will enable notification support on Windows 10 Mobile devices and enable persistent notifications in the Action Center, so that when clicked, the corresponding Service Worker can be invoked to take action.
