Sometimes the open web needs a door policy: a kid's iPhone that should not wander everywhere, or your own phone during the weeks a certain site eats your evenings. The iPhone has a proper bouncer built in, it lives inside Screen Time, and it can filter broadly, ban specific sites by name, or lock browsing down to an approved list only. Here is how to block websites on an iPhone, for their device or yours.
Where the Controls Live
The web restrictions hide one layer deep: Screen Time, then content and privacy restrictions, then the content section covering web access. The path matters less than knowing the destination exists, because most people search their browser's settings and find nothing, the door policy is enforced at the system level, covering browsing across the device rather than one app. Everything below happens in that one settings area, protected by the Screen Time passcode you set.
Level One: Filter the Adult Web
The broadest setting flips the device from unrestricted to filtered: the option to limit adult websites applies an automatic filter across browsing, catching the categories most parents worry about without any list-keeping. It is the sensible default for a child's device, one toggle, immediate effect. The filter is automatic rather than perfect, which is why the next two levels exist, but as a foundation it does the heavy lifting with zero maintenance.
Level Two: Ban Specific Sites by Name
Under the same filtered setting lives a never-allow list: add any site by address, and it is closed on this device regardless of the filter's own opinion. This is the tool for the specific site your kid found that slipped past the automatic net, and equally the tool for your own personal time sinks, the one site that turns ten minutes into ninety. Adding your own kryptonite to your own never-allow list is self-parenting, and it works better than willpower at 11pm.
Level Three: The Allow-List Fortress
For young children, flip the logic entirely: the allowed-websites-only mode closes the entire web except the sites you explicitly add. Homework resources, the school portal, a handful of approved destinations, and nothing else exists. It is the strictest mode and exactly right for the youngest users, where curating a dozen good doors beats patrolling a million bad ones. As kids grow, you graduate them down a level, from fortress to filter, matching trust as it is earned.
The Passcode That Holds It All
Every level depends on one thing: a Screen Time passcode that is not guessable and not your phone unlock code. This passcode guards the settings themselves, and kids are world-class at shoulder-surfing the code that unlocks everything else. Set a separate one, tell no one, and the door policy actually holds. For family setups, managing the child's device through Family Sharing keeps the controls on your phone entirely, which beats borrowing theirs to adjust anything.
For Your Own Phone: Friction Is the Feature
Blocking on your own device sounds paradoxical, you know the passcode, but the point is friction, not fortress. The extra steps to unblock a time-sink site are usually enough to break the autopilot tap, which is where the lost evenings actually live. Pair the never-allow list with app limits and downtime, and the phone stops volunteering distractions during the hours you care about. The bouncer works for you too; you just have to hire him.
| The level | Best for |
|---|---|
| Adult-content filter | The sensible kid-device default |
| Never-allow list | Specific sites, theirs or yours |
| Allowed-only mode | Young children, curated web |
| Separate passcode | Making any of it actually hold |
Frequently Asked Questions
How do I block a website on an iPhone?
Through Screen Time's content and privacy restrictions: enable the adult-content filter for broad coverage, add specific sites to the never-allow list to ban them by name, or use allowed-websites-only mode to close everything except an approved list. All of it locks behind a Screen Time passcode.
Can I block websites on my kid's phone from my phone?
Yes, with the child's device managed through Family Sharing, the Screen Time controls, filters, banned sites, and allowed lists, are set from your own phone. That keeps the passcode and the policy entirely in your hands without ever borrowing their device to adjust it.
What is the strictest web setting for young kids?
Allowed-websites-only mode, which closes the entire web except sites you explicitly approve: school portals, homework resources, a curated dozen doors. For young children, curating what exists beats filtering what does not, and you relax the level as trust grows.
Can I block distracting websites on my own iPhone?
Yes, and it works through friction: add your personal time sinks to the never-allow list, and the extra steps to unblock are usually enough to break the autopilot visit. Combined with app limits and downtime, it beats willpower during the hours you actually care about.
Why does my child keep getting around the restrictions?
Usually the passcode: if the Screen Time code matches the phone unlock code or was ever observed, the policy is decorative. Set a separate, unguessable Screen Time passcode, manage the device through Family Sharing, and the levels enforce themselves properly.
Does the adult-content filter catch everything?
It is automatic rather than perfect: strong as a foundation, occasionally missing a specific site, which is exactly what the never-allow list is for. The two together, broad filter plus named bans, cover a child's device realistically, with allowed-only mode as the strict fallback.
The Bottom Line
The iPhone's web door policy has three levels, all inside Screen Time: the adult-content filter as the kid-device default, the never-allow list for banning specific sites by name, yours included, and allowed-websites-only as the fortress for young children. A separate, secret Screen Time passcode is what makes any of it hold, and Family Sharing puts the controls on the parent's phone where they belong. Filter broadly, ban specifically, and graduate trust as it is earned.
