Cloudflare provides ‘1.1.1.1 for Families’ as an extra layer of protection against malware and adult content. This is an alternative to the 1.1.1.1 DNS resolver which also filters content.
This service can be used on Android, Linux, Windows, iOS, macOS and Routers.
The below guide is taken from Cloudflare Developers Docs.
Windows limited users will be unable to change these settings when devices are configured by an administrator account.
