Combine layers: switch on content restrictions in Screen Time (iPhone), Family Link (Android) or Microsoft Family Safety (Windows), add a family DNS filter on your home router, and lock app-store installs. No single tool is perfect, and children can find workarounds, so keep talking openly. Sites that carry an RTA label are easier for filters to recognise. If you see harmful content involving minors, report it.
Why one setting is not enough
Age checks on adult sites help, but they do not cover every site, and children can reach adult content through search results, social media, shared links and apps. The most reliable approach uses several layers at once: device controls, network filters, app limits and conversation.
Think about what you are protecting against. Younger children may stumble on adult content by accident, through ads or search results. Teenagers may look on purpose, and are more likely to look for ways around restrictions. The right mix of tools changes as your child grows, so plan to adjust settings every year.
iPhone and iPad: Screen Time
- Open Settings and choose Screen Time.
- Turn on Content and Privacy Restrictions.
- Open Content Restrictions, then Web Content.
- Choose Limit Adult Websites, or Only Approved Websites for younger children.
- Set a Screen Time passcode that your child does not know.
Android: Google Family Link
- Install Family Link on your phone and link your child's account.
- Open the child's controls and choose Google Chrome settings.
- Choose to try to block sexually explicit and violent sites.
- Review Google Play restrictions and require approval for installs.
Remember that other browsers and apps may need separate settings.
Windows and home Wi-Fi
On Windows computers, Microsoft Family Safety lets you filter websites and set time limits. For the whole home, many routers support family DNS filtering, which blocks adult categories on every device that joins your Wi-Fi.
| Layer | Covers | Weakness |
|---|---|---|
| Screen Time / Family Link | One phone | Other browsers, VPNs |
| Router DNS filter | All home devices | Mobile data, other Wi-Fi |
| App-store limits | Installs | Web access remains |
| Conversation | Everything | Needs trust |
Some phones also offer built-in features that warn children before they view or share sensitive images in messages. Check your device settings, and ask your mobile provider whether it offers a free network-level adult-content filter, because many do. Turn it on for your child's SIM so the filter still works when they leave your Wi-Fi.
Do not forget game consoles, smart TVs, tablets and school laptops. Each has its own settings, and a single unprotected device is often the easiest route to adult content.
The RTA label and age checks
RTA stands for Restricted to Adults. Many adult sites add this label so filtering software can recognise and block them automatically. Check that your filter supports it. Age checks required by law are an added barrier, but they are not foolproof.
Check what apps are installed, too. Some apps include built-in browsers that bypass the main browser's filters, and social platforms can expose adult material in feeds. Review the apps your child uses, set their age on each account honestly, and use the strictest content settings the app offers. Make a habit of reviewing screen-time reports together, as a conversation rather than an inspection.
Finally, think about outside the home. Friends' phones, school computers and public Wi-Fi will not have your settings. That is another reason why talking, trust and clear family rules matter as much as any software.
Talk, check in and report
Explain calmly why some sites are for adults only, and make clear that your child will not be punished for telling you if they see something upsetting. Block VPN and private-browsing options where you can, and review settings every few months.
If you come across content that appears to involve a minor, or want to flag a concern, you can use the reporting guidance here: report content.
It also helps to agree some family rules together: devices charge outside the bedroom overnight, apps are installed only after a conversation, and nobody is in trouble for asking questions. Children who feel safe to talk are far better protected than children who only face blocks.
If you are unsure where to start, begin with the one change that has the biggest effect: the router or mobile-network filter, followed by the phone's own content restrictions. You can add the rest gradually. Write down the passcodes you set and store them safely, and test the result by trying to open a blocked category yourself.
Review the settings after software updates, because updates sometimes reset options, and each new device in the home needs the same checks.
Key takeaways
- Use several layers: device, network, app store and conversation.
- Screen Time, Family Link and Family Safety include adult-web filters.
- A router DNS filter covers every device on home Wi-Fi.
- RTA labels help filters recognise adult sites.
- Open conversation works better than relying on blocks alone.
