How to Password-Protect Photos on Your iPhone

iPhone does not have a "put a password on this photo" button, but there are real ways to lock photos behind Face ID. Here is what actually works.

The built-in way: the Face-ID-locked Hidden album

The closest thing iOS has to a password on your photos is the Hidden album, which on iOS 16+ is locked with Face ID or Touch ID by default. Hide a photo (••• → Hide) and it lands there, behind your face. Confirm the lock is on in Settings → Photos → Use Face ID.

Workarounds and their catches

Notes. You can add photos to a note and lock the note with a password or Face ID. Fiddly for more than a couple.
Third-party "vault" apps. They add a passcode, but many copy your photos into a container that can upload to the cloud or be lost if you forget the password (vault vs Hidden album).

Find your private photos and lock them away

NoodBank finds your private photos on-device and hides them into the Face-ID-locked Hidden album, in bulk. Nothing uploaded, nothing copied.

The honest picture

For most people, the Face-ID-locked Hidden album is the right balance: no separate app, no upload, no data-loss risk, and it is locked behind your face. It is ideal for the everyday worry (someone scrolling your phone), just not a fortress against a determined snoop who has your passcode.

FAQ

Can you put a password on a single photo in iOS?

Not directly. The built-in option is the Hidden album, which is locked with Face ID on iOS 16+. You can also lock a Note that contains photos.

Is the Hidden album password protected?

It is locked with Face ID or Touch ID by default on iOS 16+, so it opens with your face rather than a separate password.

Are third-party photo-lock apps safe?

Some copy your photos into a container that can upload to the cloud or be lost. Prefer in-place options that do not move your photos.
