Microsoft has now released an official Chrome web browser extension that delivers its Windows 10 Timeline support to non-Microsoft devices.
Called Web Activities, the extension works with an existing Microsoft account to sync activities across devices.
With this extension, your browsing history will appear across all your devices in surfaces such as in Windows timeline and Microsoft Launcher for Android. Just sign in with your Microsoft account, select a site you’ve recently visited, and pick up where you left off.
Incidentally, this also works for Chromebooks running ChromeOS.
