Microsoft family feature already allows parents to block certain websites on PCs for their kids. Microsoft is now bringing this feature to Android mobile devices with Edge web browser.
If you already have a Microsoft family group and have marked websites as allowed or blocked for your kid, you can now bring it to Android devices with no additional work. You have to just ask or force your kids to browse the web through Edge on their Android devices. If they try to access websites in Edge on their Android devices, the same allowed/blocked websites restrictions from PC will be maintained.
This new Edge browser for Android update will begin rolling out today. You can download the Edge browser for Android here from Play Store.
