Pro Tip: Securing Your Apps and Protecting Your Phone

You probably have a lock on your phone to keep it secure, but have you considered securing your apps as well? While your phone lock provides a basic level of protection, locking individual apps adds an extra layer of security. Whether you want to protect sensitive information or curb excessive app usage, securing your apps is a smart move. In this article, we’ll explore how to put a password on individual apps on your Android device.

How to Put a Password on Individual Apps

The secret to locking individual apps on Android is utilizing third-party app-locking apps. These apps generate passcodes or patterns that you must enter before accessing a particular app. One highly recommended app for this purpose is AppLock, developed by DoMobile Lab.

Using AppLock, or any similar app, is relatively simple:

  • Download and install the app on your phone.
  • When prompted, create a unique password to use with individual apps (different from your phone’s lock code).
  • Grant AppLock permission to run on top of other apps.
  • Inside AppLock, select the app you want to lock and tap the “Lock” button.
  • Confirm the successful locking of the app by attempting to open it.

AppLock stands out because it offers fingerprint locking in addition to passcodes. It also includes features like storage space cleanup, battery saver, CPU temperature control, and device speed booster. However, there are other apps worth considering for simpler needs:

  • Smart AppLock: Offers fingerprint, pattern, or PIN protection, with low memory usage and break-in alerts.
  • AppLock Pro: Includes features like taking a picture with an incorrect passcode, a hidden “Crash screen,” and prevention of force closing or uninstalling.

Other Android Security Features to Utilize

Aside from app-locking apps, Android devices offer additional security features to protect personal data stored within apps and overall phone security.

Screen Pinning

Screen Pinning allows you to lock your phone’s screen to a specific app, preventing users from accessing other apps. To activate Screen Pinning on your Android device (Android OS 9.0 Pie or later):

  1. Go to Settings and tap on Security & Location.
  2. Tap on Advanced, then Screen Pinning.
  3. Toggle Screen Pinning to the “on” position and enable “Ask for PIN before unpinning.”
  4. Tap the Overview button (the square one) at the bottom of your screen.
  5. Select the app you want to pin, tap Pin, and confirm by tapping Got it.

Note: The instructions may vary depending on your Android device.

Screen Pinning is also useful for keeping your phone locked on a specific app, such as a game for children. To unpin an app, simultaneously tap Back (triangle icon) and Overview, then enter your PIN.

Secure Folder

Samsung Android phones feature a Secure Folder, allowing you to lock apps within a virtual folder. You can secure the folder using a passcode, PIN, password, fingerprint, or iris scan. To use Secure Folder on your Samsung Android phone:

  1. Go to Settings and select Biometrics and security.
  2. Tap on Secure Folder, then Lock type.
  3. Choose between pattern, PIN, password, fingerprint, or iris, and create the respective password.
  4. Access your app drawer and tap Secure Folder, then tap Add apps.
  5. Select the apps you want to include in the folder, then tap Add.
  6. Go back to the Secure Folder menu and tap Lock.
  7. Ensure the apps prompt for the passcode or fingerprint when accessing them.

By leveraging these Android security features, you can enhance your app and phone security.

Frequently Asked Questions

Q: Can I lock apps on an iPhone?
A: Unfortunately, Apple does not offer native app-locking features like Android. However, you can set a passcode or utilize Touch ID and Face ID to lock your iPhone or iPad. Some apps, like WhatsApp, have built-in lock mechanisms. Additionally, you can use the “Screen Time” feature to lock apps for specific periods, allowing you to control access to your apps effectively.


Protecting the apps on your phone is just as crucial as securing the device itself. By locking individual apps, you add an extra layer of protection against unauthorized access. Android users can take advantage of app-locking apps like AppLock, Smart AppLock, and AppLock Pro. Additionally, features like Screen Pinning and Secure Folder further enhance app and phone security.
