Hidden album vs a photo vault app: what each one actually protects
The Hidden album and a photo vault app solve different problems. The Hidden album in Photos removes photos from view, behind Face ID, but it opens with the iPhone passcode and the photos stay ordinary files in the library and in iCloud Photos. A vault app encrypts the photos under a key the passcode does not open. If the people you worry about know your passcode, the Hidden album is not enough.
Hidden album vs photo vault app: the one-line difference
The Hidden album controls where a photo is listed. A vault app controls who can read the file. Everything else follows from that.
What the Hidden album does
Since iOS 16, the Hidden album in Photos is locked with Face ID by default, and its photos are left out of search, widgets, Memories and the photo picker in other apps. In iOS 26 it lives in the Collections tab under Utilities. In Settings › Apps › Photos, Show Hidden Album can remove it from the list entirely, and Use Face ID keeps the lock.
What it does not do:
- It does not have its own key. Face ID on the album falls back to the iPhone passcode. Someone who knows the passcode opens the album, and can flip Show Hidden Album back on.
- It does not encrypt the photos separately. They are ordinary files in the library, present in every iPhone backup, on a Mac with iCloud Photos, and in iCloud Photos itself.
- It does not hide that it exists. Utilities › Hidden is a known place; a hidden album with a lock on it is itself a signal.
What a photo vault app does
A vault app moves the photo out of the library into a container of its own. If it is a real vault, the container is encrypted with a key that the iPhone passcode does not unlock. In Mirage Vault, each file is sealed with AES-256-GCM under its own random key; the vault key is wrapped by a key inside the Secure Enclave, so a copy of the files cannot be opened anywhere else. Unlock is a pattern drawn on a blank screen, Face ID bound to the enrolled faces, or a PIN; a forgotten pattern is recovered with an 8-word phrase, not by anyone’s support team.
What it costs you:
- A separate place. Vault photos are not in Photos: no Memories, no editing in Photos until you export them back.
- Responsibility. The recovery phrase is yours. Lose it and the pattern, and the photos are gone.
- Trust in the app. A vault app that does not encrypt is worse than the Hidden album, because it adds a false sense of safety. The seven checks tell them apart.
Hidden album vs vault app, situation by situation
| Situation | Hidden album | Photo vault app (Mirage) |
|---|---|---|
| Someone scrolls your Photos | Protected | Protected |
| Someone knows your passcode | Not protected | Protected: separate pattern and key |
| A backup or a synced Mac | Photos present, unencrypted | Encrypted files only |
| iCloud Photos | Hidden there too, as normal files | Not in iCloud Photos; own encrypted backup |
| Hiding that hidden photos exist | Partly (Show Hidden Album off) | Blank lock screen, changeable icon |
| Forced to show | Nothing | Decoy vault, Wipe Key (Pro) |
| Forgotten key | The passcode is the key | Recovery phrase, or the photos are gone |
| Screenshots of an open photo | Possible | Possible; covered during recording, logged |
| Cost | Free | Free up to 100 photos and 10 videos; Pro for more |
Which one you need
The Hidden album is enough when the problem is photos that are out of place: receipts, screenshots, a surprise gift, medical photos you would rather not scroll past. Nobody who matters knows your passcode, and the photos may stay in your library.
A vault app is the answer when someone who could unlock your iPhone must not see the photos, when a copy of your library (a shared Mac, a family iPad, a backup) must not contain them, or when you may be asked to open the vault in person. Then the separate key, the decoy and the Wipe Key are the point, and the responsibility of the recovery phrase is the price.
If a vault it is, the comparison of photo vault apps lists what five of them state about their encryption, with dates. Hiding photos on iPhone has the step-by-step for both routes.
