Unwanted sites can be distracting, unsafe for children, or inappropriate for a shared device. The right approach to how to block websites on iPhone depends on whether you want to restrict one address, filter adult content, or permit only selected sites.
iPhone provides several controls through Screen Time, but the menus and restriction levels can be easy to confuse. This guide covers each method, ways to protect the settings, and fixes to try when a blocked page remains accessible.
1. How to Block Websites on iPhone in 3 Ways
Screen Time provides three levels of website control. You can block individual addresses, filter sites that iOS classifies as adult content, or limit browsing to a small list of approved pages.
Menu names may differ slightly between iOS versions. On newer versions, begin at Settings > Screen Time > Content & Privacy Restrictions > App Store, Media, Web & Games > Web Content.
Older versions may place Web Content inside Content Restrictions.
Block Specific Websites With the Never Allow List
The Never Allow list suits situations where you want most of the internet to remain accessible but need to restrict a few websites.
Follow these steps for how to block certain websites on iPhone:
- Open Settings and select Screen Time.
- Tap Content & Privacy Restrictions.
- Turn on Content & Privacy Restrictions if it is inactive.
- Open App Store, Media, Web & Games, or Content Restrictions, depending on the iOS version.
- Select Web Content.
- Choose Limit Adult Websites.
- Scroll to the Never Allow section.
- Tap Add Website.
- Enter the complete address of the site you want to restrict.
- Tap Done, then visit the address in a browser to test the rule.
These steps also cover how to block websites on Safari iPhone, but the restriction may extend beyond Safari. Browsers and apps that display web pages through Apple’s web controls may also refuse access to the listed address.
Add the main domain rather than one individual article when you want the entire site blocked. If another version of the address still opens, add that variation separately, such as an alternate subdomain.
Automatically Limit Adult Websites
The adult-content filter attempts to restrict known explicit websites without requiring you to enter every address manually. Here is how to block adult websites on iPhone with this option:
- Go to Settings > Screen Time.
- Open Content & Privacy Restrictions and activate the main switch.
- Select the menu containing media and web restrictions.
- Tap Web Content.
- Choose Limit Adult Websites.
- Add missed websites under Never Allow when necessary.
- Add a mistakenly blocked address under Always Allow if you trust it.
- Set a Screen Time passcode so the selection cannot be changed easily.
Automatic filtering may block a legitimate page or fail to recognize a newly created adult website. Treat it as a general filter, not a complete record of every unsuitable address.
Allow Access to Approved Websites Only
This is the strictest built-in option. It limits browsing to the websites included in an approved list, making it more suitable for a younger child or a device used for a narrow purpose.
For parents considering how to block inappropriate websites on iPhone, follow these steps:
- Open Settings > Screen Time.
- Tap Content & Privacy Restrictions and turn it on.
- Open the section containing Web Content.
- Select Allowed Websites Only.
- Review the websites already shown on the approved list.
- Remove any site that should not remain available.
- Tap Add Website to enter an approved page.
- Provide the website name and complete URL.
- Repeat the process for any other permitted sites.
- Test the pages the iPhone user needs for school, work, or daily communication.
Some apps rely on web domains for sign-in, loading media, or displaying help pages. If an app stops functioning after this setting is applied, identify its required domain and add it only after confirming that the address is trustworthy.
2. Which Website-Blocking Method Works Best for You?
Choose the least restrictive setting that still meets your goal. Blocking one distracting address does not require the same controls as managing a young child’s access to the wider internet.
For context, a Pew Research Center survey of U.S. teens found that 46% described themselves as being online almost constantly. Website restrictions can form one part of a family’s rules, but they work best when children also know why certain content or browsing periods are limited.
| Your Goal | Screen Time Option | What It Blocks | Key Limitation |
| Block selected website addresses | Limit Adult Websites plus Never Allow | Addresses manually added to the blocked list | Alternative domains or unlisted versions of the site may need separate entries |
| Limit adult content automatically | Limit Adult Websites | Many websites that iOS categorizes as adult content | The filter may miss a site or restrict a legitimate page |
| Allow access only to approved websites | Allowed Websites Only | Every website that is not on the approved list | Needed sites and app login pages may require manual approval |
| Manage a child’s web access | Family Sharing with an appropriate Web Content option | Content based on the restriction level selected for the child | Technical controls still require regular review and clear family rules |
Use the Never Allow list for a small number of known addresses. Choose the automatic adult-content filter for broader protection without closing most of the web. Select Allowed Websites Only when access must remain limited to a controlled set of pages.
3. How to Lock Website Restrictions With a Screen Time Passcode
Blocking websites on iPhone will have little effect if another user can open Screen Time and reverse the changes. A separate passcode protects the restriction settings without changing the code used to unlock the iPhone.
Create a Screen Time Passcode
To protect the website settings:
- Open Settings.
- Tap Screen Time.
- Select Lock Screen Time Settings or Use Screen Time Passcode.
- Enter a four-digit code that the other user cannot guess.
- Enter it again to confirm.
- Provide an Apple Account for passcode recovery if requested.
Do not use a birthday, repeated number, or the same code used to unlock the phone. Store the code somewhere private if the restrictions manage a child’s device.
Prevent Changes to Web Content Settings
After the passcode is active, return to Content & Privacy Restrictions and confirm the main switch remains on. Open Web Content and check that the selected filter and address lists are still present.
Screen Time should request the passcode before allowing protected settings to be changed. Test this by leaving Settings, returning to Screen Time, and attempting to edit the web-content option.
If you manage a child through Family Sharing, make the changes from the family organizer’s device. This keeps the parent’s Screen Time controls separate from the passcode used to unlock the child’s iPhone.
Recover a Forgotten Screen Time Passcode
If you forget the code:
- Open Settings > Screen Time.
- Tap Change Screen Time Passcode.
- Select Change Screen Time Passcode again.
- Tap Forgot Passcode?
- Enter the Apple Account details used when the passcode was created.
- Follow the prompts to set a new code.
For a child account managed through Family Sharing, the family organizer can usually reset the passcode from the organizer’s device. Open the child’s Screen Time settings, choose the passcode option, and authenticate with Face ID, Touch ID, or the organizer’s device passcode.

4. How to Block Websites on a Child’s iPhone With Family Sharing
Family Sharing lets a parent or guardian manage web restrictions without using the child’s device each time. To set it up:
- Open Settings on the family organizer’s iPhone.
- Tap Family and select the child’s name.
- Choose Screen Time, then open Content & Privacy Restrictions.
- Turn on the restrictions and select Web Content.
- Choose Limit Adult Websites or Allowed Websites Only.
- Add specific addresses to the blocked or approved list as needed.
- Create a Screen Time passcode the child does not know.
- Test the rule on the child’s iPhone after the settings sync.
Menu locations may vary by iOS version. The child must belong to the Family Sharing group before the organizer can manage these controls remotely.
5. How to Unblock a Website or Remove the Restrictions
You can restore access to one address without disabling every Screen Time rule. Choose the action that matches the change you want:
- Unblock one website: Open Web Content, find the address under Never Allow, swipe left on it, and tap Delete.
- Approve a mistakenly blocked site: Keep Limit Adult Websites active and add the address under Always Allow.
- Expand access from an approved list: Change Allowed Websites Only to Limit Adult Websites or Unrestricted.
- Remove the web filter: Select Unrestricted under Web Content.
- Turn off all content limits: Disable Content & Privacy Restrictions after entering the Screen Time passcode.
- Remove the Screen Time lock: Open the passcode settings and choose Turn Off Screen Time Passcode.
After making the change, close and reopen the browser. If the page remains blocked, check Family Sharing controls and any filtering service installed by a school, employer, carrier, or network administrator.
