How to Hide Photos From Someone Who Knows Your iPhone Passcode

The Hidden album and locked apps both open with your passcode. Here is what actually keeps photos private from someone who knows it.

Short answer:

iPhone's own tools mostly can't. The Hidden album and locked apps both open with your iPhone passcode. The closest built-in option is a locked note with its own custom password. The stronger option is a photo vault whose key is separate from your passcode.

Why the usual tricks don’t work

Most advice for hiding photos on iPhone assumes the other person doesn’t know your passcode. Every built-in lock falls back to it:

So if someone knows your passcode, all three are a curtain, not a lock. They’re still useful against everyone else. How to Hide Photos on iPhone has the steps.

First, check who else can already get in

Before you hide anything, close the doors you may not know are open.

  1. Another face in Face ID. Face ID can hold a second “alternate appearance”. If you think someone added their face, go to Settings → Face ID & Passcode and tap Reset Face ID. Then set it up again with only your face.
  2. A Shared Library. Everyone in an iCloud Shared Photo Library can see what’s in it. Check that private photos are in your Personal Library, not the shared one.
  3. Other devices. With iCloud Photos on, your photos also appear on every iPad or Mac signed in to your Apple Account. A family iPad is only as private as its own passcode.

The simplest fix: change your passcode

If the person only saw your passcode once, changing it is the cleanest answer. Every built-in lock is secure again the moment they no longer know it.

It doesn’t help if they expect you to unlock the phone when asked, or if they share the phone with you. For that, you need something with a key of its own.

The built-in option: a locked note with its own password

The Notes app is the one place on iPhone where you can choose a lock that’s different from your passcode.

  1. Go to Settings → Apps → Notes → Password and choose a custom password instead of your iPhone passcode.
  2. Create a note, add the photos, then lock it.
  3. Delete the originals from Photos, then empty Recently Deleted too. The note holds its own copy, so the originals stay behind until you do.

Things to know before you rely on it:

Why Stolen Device Protection doesn’t solve it

Stolen Device Protection is worth turning on. With it, locked apps need Face ID or Touch ID with no passcode fallback, but only when your iPhone is away from familiar places like home and work.

At home, the passcode still opens everything. That’s exactly where the person you’re thinking of probably is.

The stronger option: a vault with its own key

A photo vault helps only if its lock is genuinely separate from your phone. When you compare apps, look for these:

That’s what Hidlet is built for:

If someone is pressuring you

If you’re hiding photos because someone checks or controls your phone, your safety matters more than any app. Apple’s Personal Safety guide covers how to check who has access to your devices and accounts. If you’re in danger, contact local emergency services or a support line in your country.

Frequently asked questions

Can I give the Hidden album a separate password?

No. The Hidden album uses your iPhone's lock, so Face ID, Touch ID or your passcode opens it.

Does locking the Photos app stop someone who knows my passcode?

No. A locked app opens with Face ID, Touch ID or your passcode, so anyone with the passcode can open it.

Can I lock photos in the Notes app?

Yes. Notes can use a custom password that is different from your iPhone passcode. Notes with videos, audio or PDFs can't be locked.

Will someone see that I use a vault app?

Possibly. Even a hidden app's name can still appear in Screen Time, Battery usage in Settings and your App Store purchase history.
