How to Lock the Photos App on iPhone in 2026
iOS 18 lets you put Face ID in front of the Photos app itself. What that changes, what it leaves open, and how it compares to the Hidden album and a vault.
On iOS 18 and later: touch and hold the Photos icon, tap Require Face ID, and confirm. Photos then needs Face ID, Touch ID or your passcode to open. Its contents stop appearing in notification previews, search and Siri suggestions. The lock opens with your phone passcode, so it stops a casual look rather than someone who knows the passcode. It changes nothing about iCloud. You cannot hide the Photos app itself. Apple does not allow built-in apps to be hidden.
1. Lock the Photos app
Apple's steps, which need iOS 18 or later:
- Go to the Home Screen and find Photos.
- Touch and hold the icon until the quick actions menu opens.
- Tap Require Face ID (or Touch ID, or Passcode).
- Tap it again to confirm, and unlock with Face ID or your passcode.
From then on, opening Photos asks for Face ID, Touch ID or your passcode. To remove the lock, touch and hold the icon again and choose the option that no longer requires it.
2. What the lock does, in Apple's words
"The app requires Face ID, Touch ID, or your passcode to open. Information inside a locked app won't appear in some locations on your iPhone, for example, in notification previews, search, Siri suggestions, or your call history."
That second sentence is the part people miss, and the reason the feature is worth using. A locked Photos app is not just a prompt on the icon. Apple's list includes search and Siri suggestions. Those are two of the more common ways a photo pops up without anyone opening the app. The Hidden album keeps hidden photos out of the rest of Photos. Locking the app covers the whole library, on the places Apple names.
3. Why you cannot hide the Photos app
iOS 18 also lets you hide an app entirely. A hidden app moves to a Hidden folder at the bottom of the App Library, which needs Face ID or your passcode to open. Apple states that apps which come installed with iOS cannot be hidden, and Photos is one of them. Apple also lists a set of built-in apps that cannot be locked at all: Calculator, Camera, Clock, Contacts, Find My, Maps, Shortcuts and Settings. Photos is not on that list. So locking works, and hiding does not.
A downloaded app can be both locked and hidden. That includes vault apps, ours among them. Worth knowing before you rely on it: Apple states there are other places you may be able to see the names of hidden apps, and lists them. Settings under Apps then Hidden Apps, Screen Time, Battery Health & Charging, and your App Store purchase history. Hiding removes an icon from the Home Screen. It does not remove the record that the app exists. That is the same limit we describe for our own Calculator Mode.
4. What the lock leaves open
Your passcode
The lock opens with your phone passcode. Anyone who knows it can open Photos exactly as before. This is the same as the Hidden album, and for the same reason. Both are part of a phone the passcode already unlocks.
iCloud
The lock lives on this phone. iCloud Photos keeps syncing the whole library, hidden photos included, to every device signed in to your Apple Account. And Apple can still read it under the default setting. Our guide to the Hidden album and everywhere else a photo lives covers that in full.
Other apps with photo access
Locking Photos does not lock the photos. Any other app you have given access to your library can still read them. Check that list in Settings under Privacy and Security.
The file itself
Nothing about the lock changes how a photo is stored. It is a prompt in front of an app, not a second key on the data. If the risk you have in mind is someone with your passcode, or a copy of the storage, a prompt does not deal with it. Encryption with a password that is not your passcode does. That is the whole difference between this feature and a vault app that encrypts. It is set out side by side in the Hidden album vs a photo vault app.
5. Locked app, Hidden album, or vault
| Option | What it covers | Opens with | Effect on the file |
|---|---|---|---|
| Lock the Photos app | The whole library, plus search and Siri | Face ID, Touch ID or your passcode | None |
| Hidden album | Chosen photos, out of the library, widget and Memories | Face ID, Touch ID or your passcode | None |
| Encrypted vault app | Chosen photos, moved out of Photos entirely | Its own password | Encrypted, if the app encrypts |
There is no password for an album or a folder in iOS. What it offers instead is collected in how to password-protect photos and folders. The first two rows go well together and cost nothing: lock the app, hide the sensitive few, and turn off Show Hidden Album. For most people that is the right amount of effort. The third row is for the case where the person you are hiding from has your passcode. It comes with a real cost of its own: a forgotten password is usually permanent. The steps for every option are in how to hide photos on iPhone.
6. Common questions
Can you lock the Photos app on iPhone?
Yes, on iOS 18 and later. Touch and hold the Photos icon on the Home Screen, tap Require Face ID (or Touch ID or Passcode), and confirm. The app then needs Face ID, Touch ID or your passcode to open. Its contents stop appearing in notification previews, search and Siri suggestions.
Can you hide the Photos app on iPhone?
No. Apple states that apps which come installed with iOS 18 or later cannot be hidden, and Photos is one of them. You can lock it, and you can hide the Hidden album inside it from view in Settings. But the Photos icon itself stays.
Does locking the Photos app hide photos from iCloud?
No. The lock is a prompt in front of the app on this phone. It changes nothing about iCloud Photos, which keeps syncing your library, hidden photos included, to every device signed in to your Apple Account.
Does a locked app stop someone who knows my passcode?
No. The lock opens with your phone passcode as well as Face ID. So anyone who knows the passcode can open a locked app. It stops a casual look, not a person with the passcode.
Can I lock a vault app with Face ID too?
Yes. Any downloaded app can be locked, and unlike Photos it can also be hidden in the App Library's Hidden folder. That puts an iOS lock in front of the app's own lock. But two locks that both open with your passcode are still one password. A vault app's own password is the one that is separate.

Obscura Photo Vault
An encrypted photo vault for iPhone. Photos and videos are encrypted on your device with AES-256-GCM. There are no accounts, no servers and no analytics, and the app does not require a network connection. If you forget your password, nobody can recover the contents, including us.
