Hiding a photo
is not the same as protecting it.

On iOS 18 and later, lock the Photos app with Face ID, Touch ID, or your passcode. That lock is for this iPhone. Apple does not document a separate vault key. If the files must stay unreadable, import them into ArkWarden.

Apple does not let you password-protect a Files folder. In ArkWarden you create folders inside a category. Every file is already encrypted. The vault opens with your pattern.

Touch and hold a photo, then tap Hide. Apple's Hidden album adds no separate key. ArkWarden encrypts your photos instead, unlocked by your pattern.

Yes, when iCloud Photos is on. Hiding changes the album, not whether the photo is in iCloud. How to check, how to stop it, and what stays out of Photos.

Most vault apps come down to two questions: does the file itself become unreadable without a key, and who besides you could get that key. Here's how the apps people ask about most actually answer them.

There are five real ways to hide photos on an iPhone, and each one stops a different kind of look. Here's what each one actually stops, and why encryption is the only one built to survive someone holding the device itself.

A deleted photo waits 30 days in Recently Deleted, where your passcode still opens it. Delete it twice to remove it. In ArkWarden, with Trash off by default, one delete removes the encrypted file at once.
