3 FAQs about Google Chrome parental controls

Yes, you can apply the feature on Android and Chromebook with the help of the Family Link app.

Google decided to abandon “supervised users” since January 2018. Later, Google released a replacement Family Link to manage your kids’ browsing activity on Google Chrome.

And only a few countries can use it.

#2 What is Google SafeSearch and how to turn it on?

SafeSearch, one of the Google Chrome parental control settings, can help filter out inappropriate content (e.g., over 18 sites, violent sites and explicit images or videos) on Chrome from your results.

1. To turn on Google SafeSearch, first open the Google homepage.

2. Click Settings in the lower right corner.

3. Choose Search settings option from the pop-up menu.

4. Check the Turn on SafeSearch box to enable SafeSearch filters.
