How to Lock Photos on iPhone With Face ID

The quickest way to lock photos on iPhone with Face ID is the built-in Hidden album, which has been locked behind Face ID, Touch ID, or your passcode by default since iOS 16. On iOS 18 you can go further still and require Face ID to open the whole Photos app. Both keep your pictures out of casual view — and it helps to know exactly what that lock does, and what it doesn't.

Quick answer

You have two built-in options, and they stack. Hide a photo and it moves to the Hidden album, which asks for Face ID before it opens. Or, on iOS 18 and later, lock the Photos app itself so the entire app needs Face ID. Want the full menu of choices? The guide on how to hide photos on iPhone compares every method. For locking specifically, the steps below take about a minute.

Step-by-step

Hide a photo to the Face ID-locked Hidden album

Open Photos, tap and hold the photo or video you want to tuck away, then tap Hide and confirm. It disappears from your Library, your other albums, and the Photos widget. To see it again, tap Collections, scroll to Hidden under Utilities, tap View Album, and authenticate with Face ID or Touch ID. Since iOS 16, the Hidden album is locked by default, so there's nothing extra to switch on.

Customize the lock and hide the album from view

To choose which methods unlock it, open Settings, tap Apps, then Photos, and toggle Use Face ID, Use Touch ID, or Use Passcode. In the same place you can turn off Show Hidden Album, which removes the album from Photos entirely — there's nothing left to tap on.

Lock the entire Photos app (iOS 18 and later)

Touch and hold the Photos icon on your Home Screen, tap Require Face ID, and confirm. Opening Photos now asks for Face ID, Touch ID, or your passcode every time. Apple's app lock also keeps a locked app's contents out of search, notification previews, Siri suggestions, CarPlay, and your call history. Built-in apps like Photos can be locked this way, though they can't be moved into the hidden App Library folder.

Common problems and what Face ID does not cover

If your Hidden album opens without asking for Face ID, either the toggle is off in Settings > Apps > Photos, or you authenticated a moment ago and the gate hasn't re-locked yet.

Here's the part worth being clear about. Face ID is a convenience layer; your passcode is the root of trust. Apple's security documentation notes that the passcode is still required after a restart and to change security settings — so anyone who knows your passcode can simply turn the lock back off. The Hidden album and the app lock are access gates inside an already-unlocked phone, not a second encrypted container. As the EFF explains, encryption at rest protects a locked device, but once the phone is open, whatever is on screen is available to whoever is holding it. That's why the Hidden album is a view filter, not a separate encrypted container. One more detail: if you use iCloud Photos, hiding a photo syncs that hidden state to your iPad and Mac too.

Doing this with Privara

Sometimes a photo needs to stay yours — not just out of sight. For that, the best option is a vault with its own encryption key, separate from your iPhone passcode. That's what Privara does. Privara keeps your photos, videos, documents, and contacts behind one AES-256 encryption layer inside an app that looks and works like an ordinary calculator. Enter your PIN on the calculator and the vault opens; enter anything else and it stays a calculator.

Because that lock is a real cryptographic boundary, knowing your iPhone passcode isn't enough to open it. There's no account to create and nothing is uploaded by default, Face ID or Touch ID can sit on top of your PIN, and break-in detection can capture a photo of anyone who tries the wrong one. Turn on iCloud sync and your vault follows the backup rules you choose — so decide that deliberately. For the photos, videos, documents, and contacts you'd rather keep private, Privara is the best place to put them. Download Privara on the App Store.

Frequently asked questions

Does locking the Hidden album with Face ID encrypt my photos?

Not separately. Your whole iPhone is encrypted at rest while it is locked, but the Hidden album's Face ID prompt is an access gate inside the unlocked phone, not a second encrypted container. Anyone who knows your passcode can still reach it.

Can I require Face ID to open the entire Photos app?

Yes, in iOS 18 and later. Touch and hold the Photos icon, tap Require Face ID, and confirm. After that, opening Photos asks for Face ID, Touch ID, or your passcode, and its contents stay out of search and notification previews.

Why does my Hidden album open without asking for Face ID?

Either the lock is turned off in Settings > Apps > Photos, or you already authenticated this session. Check that Use Face ID is on, and remember the gate only applies until the album re-locks.

What happens to hidden photos if I use iCloud Photos?

Hiding syncs. A photo you hide on your iPhone is hidden on your iPad and Mac as well. The hidden state travels with your library — and so does the photo itself, so the same access rules apply on every signed-in device.
