Here's how to block websites on iPhone with iOS 26: open Settings, tap Screen Time, then Content & Privacy Restrictions, and turn it on. Tap App Store, Media, Web, & Games, then Web Content. Select Limit Adult Websites, tap Add Website under Never Allow, and enter the address. Then lock it with a Screen Time passcode.
Apple reorganized Screen Time in iOS 27, and the website options look different there, so that has its own section below. You'll also find the honest limits of website blocking and what to do about them.
Open the Settings app.
Tap Screen Time. To block sites on your child's iPhone from here, tap your child's name.
Tap Content & Privacy Restrictions, then turn on Content & Privacy Restrictions.
Tap App Store, Media, Web, & Games, then tap Web Content.
Select Limit Adult Websites.
Under Never Allow, tap Add Website and type the address of the site you want to block.
Repeat for each site on your list.
In Apple's steps, the Never Allow list sits under Limit Adult Websites, so you select that option first. Apple describes Limit Adult Websites as automatically limiting access to websites it detects as adult, so you get that filter as well as your own list.
Spend two minutes writing down the sites that cost you the most time before you start. A typical list might look like this:
A news site you refresh all day
A shopping site you browse when you're bored
A forum or video site that turns five minutes into an hour
After you add each one, open Safari and try to visit it. If it still loads, compare the address you typed with the one in Safari's address bar and add that version too.
Without a passcode, anyone holding the phone, including you, can take a site off the list in a few taps. A Screen Time passcode has to be entered before Screen Time settings can be changed.
Open Settings and tap Screen Time.
Scroll down and tap Lock Screen Time Settings. On iOS 27, tap Manage Screen Time first.
Enter a four-digit passcode, then enter it again to confirm.
After setting it, you can also turn on Screen Time Passcode Recovery, which lets you reset a forgotten code with your Apple Account. If you're blocking sites for your own self-control, try asking someone you trust to type in a code you don't know.
Apple says the latest Screen Time features need iOS 27 or later on all your Apple devices, and on every device in a Family Sharing group if you use one.
Apple's iOS 27 iPhone User Guide describes Content & Privacy Restrictions for content in Books, Movies, TV Shows and Music, plus built-in features and Siri. It doesn't describe a list of blocked websites for your own iPhone. What it does say is that Time Allowances can cover websites: if an app declares an associated website, that app's allowance applies to both.
Open Settings, tap Screen Time, then tap Time Allowances.
Under Time Allowances, tap a category such as Social Media.
Drag the slider, or tap the Minus and Plus buttons, to set how long you get each day.
On your own iPhone, open Settings, tap Family, then tap your child's name.
Tap Apps & Websites.
Tap the Add button, then enter the name of the website to block it.
To filter rather than list sites, tap Apps & Websites, then Restrictions, then Filtering under Websites. Choose Approved Websites Only, Limit Adult Websites or Unrestricted. Apple turns on Approved Websites Only by default for Child Accounts under 13, and Limit Adult Websites for Child Accounts under 18. Ages may vary by country or region.
Other browsers. Apple's families guide describes blocking websites in Safari, and the iOS 26 steps don't say which other browsers follow the Never Allow list. Test each site in every browser on your phone. If a second browser gets around it, delete that browser or give it a short limit under Screen Time, App Limits, Add Limit.
Apps. Blocking a website doesn't block its app. If the site has an app, block or limit that app as well.
Detection. The adult filter works on sites Apple detects. Detection isn't a guarantee, so add any specific site that matters to Never Allow yourself.
You. On your own phone, if you know the passcode, the block is a speed bump rather than a wall. Even so, the pause before typing the code can be enough to change your mind.
Screen Time's Never Allow list is all or nothing: a site is blocked until you remove it. A blocker app may suit you better if you want to:
Let yourself into a site or app for a few minutes, then have it lock again on its own
Keep blocked sites and their matching apps in one list
Have a way out for real emergencies that doesn't mean deleting all your rules
Before you install one, check its privacy label in the App Store and whether it needs an account. Our guide on how to block apps on iPhone compares Screen Time with blocker apps in more detail.
Go back to where you blocked it. On iOS 26 that's Settings, Screen Time, Content & Privacy Restrictions, App Store, Media, Web, & Games, then Web Content, where the site sits under Never Allow. For a child on iOS 27, open Apps & Websites, tap the Blocked tab and allow it again.
Apple's steps don't say. Its families guide describes blocking in Safari, so test any other browser you use, and remove or limit it if the site still loads.
Yes. The block works without one, but anyone with the phone can undo it. A Screen Time passcode is what stops changes.
Check that Content & Privacy Restrictions is on, that Limit Adult Websites is selected, and that the address matches the one Safari shows. Then make sure you're not using another browser or the site's own app.
If you want sites and apps blocked together with a planned way back in, FocusPass: App Blocker blocks the apps, categories or websites you choose using Apple's Screen Time picker. When you open a blocked app, you can go back or take a timed Pass, such as 5, 10 or 15 minutes, and it relocks automatically when the Pass ends, even if FocusPass is closed. It has no account and no ads, your rules stay on your device, and its Turn Off All Protection option is never locked behind a purchase or streak.
