Anyone handing an iPhone to a friend can long-press an app and require biometric authentication on the spot. Pick up a Samsung Galaxy device, though, and you will quickly notice that One UI refuses to offer that exact one-tap shortcut.
Samsung dropped simple native app locking years back. Instead, the company handles privacy across two separate utilities built into its software: hardware-isolated security through Secure Folder, and quick display containment through app pinning. Neither tool mirrors Apple's direct toggle, but each handles a different everyday scenario.
Isolating Data With Secure Folder
For banking platforms, messaging clients and personal image galleries, Samsung relies on its Knox security architecture. Secure Folder does not merely slap a gate over an existing program on your home screen. It spins up an encrypted sandbox on local storage, creating a standalone duplicate of whatever application you drop inside.
That architecture keeps logins, cached records and background syncs partitioned from the rest of the handset. Setting it up takes several steps through the device settings:
- Head into Settings, tap Security and privacy, choose More security settings, and open Secure Folder.
- Pick an authentication barrier, which can be a biometric fingerprint read, a pattern, a custom password or a numeric PIN.
- Decide whether the contained apps can continue background operations while the folder stays locked.
- Hit the plus symbol inside the vault to copy over whichever programs you want secured.
Owners can also tuck the vault completely out of view. Toggling off the shortcut icon from the quick panel drops the container off the home screen entirely. When hidden, the software halts background execution and stops incoming alerts until you manually expose and unlock the directory again.
Locking Down Single Screens With App Pinning
Encrypted vaults make sense for financial details, yet they are clumsy when all you want is to stop a toddler from leaving a video stream or opening an email client. That is where app pinning steps in.
Pinning does not encrypt databases or hide information. It freezes the handset on whichever interface is currently running, blocking access to other menus, notifications and system utilities.
Activating the feature requires heading into Settings, selecting Security and privacy, entering More security settings, and enabling the option to allow pinned screens. From there, pull up the active tasks view using the navigation bar buttons or the upward swipe gesture, tap the top icon of the app you want to isolate, and pin it.
Unpinning the display requires pressing the Recents and Back controls together. Because One UI shows written instructions on how to escape the lock right on the glass, pinning works best for very young children who cannot read the prompts.
Both features remain standard across Samsung's software lineup. Galaxy users managing private files can configure Secure Folder immediately, while those handing their devices over for short gaming sessions can stick to system pinning.
