How to Block Websites on an iPhone in 2026

If you’ve been hoping there’s a built-in way to block websites on your child’s iPhone without grabbing their device every time something needs adjusting, Screen Time is the answer. You can filter adult content automatically, block specific URLs by hand, or lock the phone to an approved list. Set a Screen Time passcode and your child can’t undo any of it.

For the initial setup, you’ll need the child’s iPhone in hand. If their device is already part of your Family Sharing group, you can manage most restrictions remotely from your own iPhone after the first-time setup.

Turn On Screen Time and Set a Passcode

The Screen Time passcode is what makes everything else stick. Without it, any restriction you set can be turned off in about ten seconds.

1. Open Settings on the child’s iPhone.
2. Tap Screen Time.
3. If Screen Time is off, tap Turn On Screen Time and follow the prompts. When asked, choose This is My Child’s iPhone.
4. Tap Use Screen Time Passcode and create a 4-digit code your child doesn’t know.

Make it different from the iPhone’s unlock code. If they’re the same, the restriction is basically decorative.

Enable Content & Privacy Restrictions

1. In Screen Time, tap Content & Privacy Restrictions.
2. Toggle Content & Privacy Restrictions on.

Block Adult Websites

1. From Content & Privacy Restrictions, tap App Store, Media, Web & Games. On some iPhones or iOS versions this may appear as Content Restrictions instead; Web Content will be inside either path.
2. Tap Web Content.
3. Select Limit Adult Websites.

Apple’s filter automatically blocks a broad list of known adult sites. No automated filter catches everything, but this covers most of the obvious cases without any manual work on your end.

Block Specific Websites

The automatic filter covers the broad strokes. For anything specific, like TikTok, Reddit, gaming sites, or social platforms, you’ll need to add URLs manually.

With Limit Adult Websites selected in Web Content:

1. Scroll down to the Never Allow section.
2. Tap Add Website.
3. Enter the full URL, for example, www.tiktok.com

, then tap Done.

4. Repeat for each additional site.

This works for any site, not only adult content. You’re not limited to the automatic filter’s categories.

Allowed Websites Only (For Younger Kids)

For younger children, Allowed Websites Only flips the approach. It blocks everything except a list you explicitly approve.

1. In Web Content, select Allowed Websites Only.
2. Apple includes a short starter list of kid-friendly sites. Remove anything you don’t want and add sites your child needs by tapping Add Website.

This mode is strict. Homework portals, school login pages, and many legitimate educational sites get blocked by default. For older kids who need the internet for school, Limit Adult Websites with a solid Never Allow list is the more practical setup. Reserve Allowed Websites Only for younger children or shared family devices.

Managing Multiple Devices with Family Sharing

If your child uses an iPhone and an iPad, Screen Time needs to be enabled on each device separately. Each needs to be signed into the child’s Apple ID and included in your Family Sharing group.

Once that’s set up, open Settings > Screen Time on your own iPhone. Your child’s name appears under Family. Tap it to adjust their restrictions without touching their device.

Downtime and App Limits

Website blocking is where most parents start, but Downtime and App Limits are worth setting up alongside it.

Downtime puts the phone on a schedule. During the window you define, only allowed apps and phone calls work. No Safari, no games, no social apps.

1. In Screen Time, tap Downtime.
2. Toggle Scheduled on.
3. Set the start and end times and choose which days apply.

App Limits cap daily time on app categories without blocking them entirely.

1. Tap App Limits in Screen Time.
2. Tap Add Limit.
3. Choose a category such as Social Networking, Games, or Entertainment, or drill down to a specific app, then set the daily time allowed.

Once the limit runs out, the app icon grays out with an hourglass. Your child can request more time, and you approve or deny it from your own iPhone.

Third-Party Parental Control Apps

Screen Time handles the basics well. If you want detailed logs of which sites your child actually visited, cross-platform controls across iOS and other devices, or better monitoring of YouTube specifically, third-party apps are worth considering.

The main options in 2026:

• Net Nanny with strong web filtering and content analysis across platforms
• Qustodio with detailed activity reports and per-app time controls
• OurPact with good scheduling and app blocking
• Norton Family with deep web filtering and solid reporting

Every iOS parental control app works within Apple’s framework. None of them replace Screen Time entirely. The practical setup: Screen Time as your baseline, with one of these layered on top if you need more visibility into day-to-day activity.

Troubleshooting

A blocked site still loads

Two likely causes: the URL isn’t in the Never Allow list (Apple’s automatic filter doesn’t catch everything), or your child opened it in a different browser. Add the exact URL manually under Never Allow, and if needed, block other browsers outright: go to Settings > Screen Time > Content & Privacy Restrictions > Allowed Apps, then turn off Chrome, Firefox, or any other browser you don’t want available — that leaves Safari, with your restrictions, as the only way to browse.

Your child turned the restrictions off

This only happens without a Screen Time passcode. Set one now, and keep it different from the iPhone’s unlock code.

Blocked sites still work inside apps

Web Content filtering covers Safari and in-app browsers that use Apple’s web engine. Content inside standalone apps like YouTube and TikTok isn’t affected when those apps handle their own playback. Use App Limits or Allowed Apps to restrict those directly, or add a parental control app that can monitor them.

Allowed Websites Only blocked too much

Switch to Limit Adult Websites and build a Never Allow list instead. You trade some coverage for practicality, which older kids doing homework will appreciate.

The menus look different from these steps

Apple occasionally renames items inside Screen Time. If you can’t find App Store, Media, Web & Games, look for Content Restrictions; Web Content will be inside either path.

Screen Time gets the job done for most families, and the passcode is what makes it stick. Get the web content filter running, add the specific sites that matter to the Never Allow list, and you’ve built something that holds up better than most parents expect. The persistence of setting it up properly pays off every time they try to get around it and can’t.
