Hidden album vs photo vault
Last updated 2026-08-05
These two are constantly described as alternatives to each other. They are not the same kind of thing. One changes where a photo is displayed; the other changes what the photo is on disk.
What the Hidden album does
Hiding a photo moves it out of your main library view and into a Hidden album, which iOS locks behind Face ID. The file itself is untouched: same format, same readability, still in your photo library, still syncing to iCloud Photos if that is on.
It is a display rule. That is the correct mental model, and it explains every limitation below.
What a photo vault does
A vault re-encrypts the file with its own key, derived from a passcode you choose, and removes the original from the photo library. The bytes on disk become unreadable without that key - including to the operating system, to a backup, and to anyone imaging the storage.
Side by side
| Hidden album | Encrypted vault | |
|---|---|---|
| What it changes | Where the photo is shown | What is written to disk |
| File on disk | Ordinary readable image | Ciphertext |
| Key | Your device passcode / Face ID | A separate passcode you choose |
| Location | Fixed and well known | Inside the app's own storage |
| Syncs to iCloud | Yes | No, in Vaultly's case |
| Survives the phone being taken | No | Yes |
| Recoverable if you forget the key | Yes, via your Apple Account | No |
| Cost | Free, built in | Usually a paid app |
The one row that decides it
Look at the key row. The Hidden album is opened by your device passcode - the same six digits you type on a train, in a shop, in front of your family. Anyone who has ever watched you unlock your phone already holds the key to your Hidden album.
A vault's passcode is separate. That separation is the entire product; everything else is detail.
When the Hidden album is genuinely enough
It is enough, and a vault app is a waste of money, if all of the following are true:
- Nobody else ever holds your unlocked phone.
- Nobody else knows your device passcode.
- You are hiding things that are private rather than damaging - a surprise gift, a screenshot you do not want surfacing in a memories widget.
Most advice in this category will not tell you that, because most of it is written by people selling vault apps. It is still true.
When it is not enough
- Someone you live with knows your device passcode.
- You hand your phone over to show a photo, and the other person keeps scrolling.
- You carry ID documents, bank letters or medical scans in your camera roll.
- You travel through places where you might be asked to unlock your phone.
That last case needs more than encryption - it needs something safe to show. That is what a decoy vault is for.
Using both
They are not exclusive. A reasonable arrangement is the Hidden album for mildly private things you still want in iCloud, and a vault for documents and anything genuinely damaging. Vaultly handles the second job: AES-256-GCM on device, a passcode separate from your device passcode, and no networking code at all, so the contents cannot leave the phone.

Questions
Is the iPhone Hidden album secure?
It is secure against casual browsing, and locked behind Face ID since iOS 16. It is not secure against anyone who knows your device passcode, because that passcode opens it. The photos themselves stay as ordinary readable files in your library.
Do photo vault apps really encrypt photos?
Good ones do, but the claim is worth checking rather than trusting. Two useful tests: whether the app works fully in Airplane Mode, and whether its App Store privacy label declares that no data is collected.
Can I use the Hidden album and a vault app together?
Yes, and it is a sensible split. Keep mildly private photos in the Hidden album where they still sync to iCloud, and put documents, IDs and anything genuinely damaging in an encrypted vault.
Does moving a photo to a vault remove it from iCloud?
It removes it from your device's photo library, which then propagates to iCloud Photos. Copies already in an iCloud backup or shared album are not affected, so check those separately.
