How to Permanently Block Porn on iPhone Without a Second Device or Another Person's Help
4 min read · Updated September 2026
Most advice about locking down an iPhone assumes you have a willing partner, a trusted friend, or a second device to help set it up. Not everyone does — and needing one shouldn't be the reason this doesn't work for you.
The manual version needs someone else. This doesn't have to.
If the whole point is a passcode you don't know, something has to generate it that isn't you.
Doing this entirely by hand usually means asking another person to set your Screen Time passcode and hold onto it, or using a second device to generate a code you then deliberately avoid learning. Both depend on someone or something outside your own phone being involved — which is a real obstacle if there's no one you want to ask, or no spare device available.
What actually makes it hold without a person involved
The requirement was never specifically "a human being." It was always just: a passcode generated by something other than you, that you can't reach on your own. A service can fill that role exactly as well as a person can, without asking anything of anyone in your life.
What still has to be true either way
Content & Privacy Restrictions has to be turned on with Limit Adult Websites enabled, and Screen Time Passcode Recovery has to be off — see the full mechanics in our main iPhone guide. None of that changes; only who or what holds the passcode does.
A passcode nobody has to be asked to keep is, if anything, a more reliable arrangement than one a well-meaning person is holding under pressure.
Doing it without asking anyone
ScreenVow generates and encrypts the passcode itself, for a period you choose — no partner to ask, no spare device to borrow, and no one who could eventually be talked into giving it back early. See the step-by-step setup guide to do it entirely on your own.
Frequently asked questions
Can I set a permanent restriction entirely by myself?
Not with the fully manual method — that requires someone else to set and hold a passcode you don't know. A service that generates and holds it for you removes that requirement entirely.
What if I don't have anyone I'd feel comfortable asking?
That's a common and reasonable position to be in. It's exactly the gap a commitment device designed to remove the human dependency is built to close.
Is a solo method as strong as having a person involved?
It can be stronger, in one specific way: there's no person who could eventually be persuaded to give the passcode back early, because no person has it in the first place.
Ready to make it stick?
ScreenVow holds your Screen Time passcode for you, so the decision can't be undone on impulse.
