We all store highly private photographs on our iPhones. These might include pictures of sensitive medical records, confidential financial documents, or deeply personal memories that we absolutely do not want friends, family, or coworkers to see when they are casually swiping through our camera roll to look at vacation photos. For years, Apple allowed you to move these photos to a dedicated “Hidden” album, but there was a massive flaw: anyone holding your unlocked phone could simply scroll down, tap the Hidden album, and view everything inside. Fortunately, Apple has finally fixed this by allowing you to mathematically lock this folder behind your biometric scanner.
How to Enable the Biometric Lock
To secure your privacy, you must explicitly instruct iOS to require Face ID (or Touch ID on older models) before opening the restricted albums.
- Open the Settings app on your iPhone.
- Scroll down the long list of options until you find Photos. Tap it.
- Scroll down to the section labeled Use Face ID (or “Use Touch ID”).
- Toggle the switch to the ON position (it will turn green).
This setting instantly applies biometric protection to both your Hidden album and your Recently Deleted album.
How to Hide a Photo
Now that the vault is secure, you need to actually put your sensitive photos inside it.
- Open the standard Photos app.
- Tap on a private photograph to view it in full screen.
- Tap the three dots (…) icon in the top right corner of the screen.
- Tap Hide from the drop-down menu.
- Confirm your choice by tapping Hide Photo.
The photo will instantly vanish from your main camera roll. If a nosy friend scrolls down to the “Albums” tab and attempts to tap the “Hidden” folder, the iPhone will physically refuse to open it. The screen will display a lock icon and demand that you, the true owner, look directly into the camera lens to authenticate the request via Face ID.
