Sometimes, keeping prying eyes out of your personal apps isn’t just about privacy—it’s about peace of mind. Whether it’s safeguarding sensitive messages, protecting your banking app, or hiding your photo gallery before a repair, adding a password or biometric lock to specific apps can make your device feel much more secure. Here's how to do it on both Android and iPhone, in just a few simple steps.
Lock apps natively on Android
Some Android phones come with built-in features to lock apps—no extra downloads needed. Depending on your device, here’s how to activate this security layer.
On Samsung devices
Samsung offers a feature called Secure Folder, which lets you store apps, files, and even photos in a separate, locked space:
- Go to Settings
- Tap Biometrics and security
- Select Secure Folder
- Choose your preferred lock type (PIN, password, fingerprint, etc.)
Once set up, you can move apps into the folder, effectively locking them behind your chosen method of authentication.
On Huawei devices
Huawei provides an app-specific locking tool that gives you control over each app:
- Open Settings
- Go to Security
- Select App lock and tap Enable
- Choose the apps you want to lock and set a secure method (PIN, face recognition, or fingerprint)
It’s easy to toggle individual apps on or off, which is great for tailoring your protection.
On Stock Android
For phones running a clean version of Android (like Pixel devices):
- Go to Settings
- Navigate to Privacy
- Tap App Lock and set a password
- Select the apps you want to protect
This native option gives you quick control without third-party apps.
Use a third-party app for universal compatibility
If your phone doesn’t offer built-in app locking, don’t worry. There are reliable apps that fill the gap. One of the most trusted is AppLock, available on the Google Play Store:
- Download AppLock and launch it
- Set a unique passcode (different from your phone’s lock screen is best)
- Browse the list of apps and tap the padlock icon to secure the ones you want
Within AppLock’s settings, you can tweak features like security questions, lock delay times, and even hide the app itself for added protection. It’s a flexible tool that works across most Android devices.
Locking apps on iPhone just got easier
With iOS 18, Apple finally introduced a native way to lock apps with Face ID or Touch ID—no workarounds required:
- Press and hold the app icon you want to lock
- Tap Require Face ID/Touch ID
- Once set, any attempt to open the app will prompt biometric authentication
This works with most third-party apps and some Apple apps too, though a few system apps like Calculator and Maps are exempt. If you want an extra layer of privacy, you can even hide apps from the home screen entirely.
Whether you're lending your phone to a friend, sending it for repair, or just prefer to keep certain apps off-limits, these tools make it easy to stay in control. With a few quick taps, you can turn your device into a fortress—at least when it comes to your private apps.
