Most people tend to use some form of biometric lock or PIN protection on their Android devices for security reasons alone. However, there may be cases when you want to lock a specific app on your device for added security. Some apps, such as password managers and banking apps, offer a built-in app lock function, which most other apps lack.
Thanks to the flexibility Android offers, locking apps on your Android device is pretty quick. Just follow the guide below.
How to lock Android apps
Many third-party apps on the Google Play Store allow you to lock apps on your Android device. Aside from app lock, these apps also allow you to lock system settings and toggle behind a passcode or password.
It goes without saying that when you lock an app, you should use a pattern or PIN that is different from your device’s unlock pattern. Using the same unlock pattern / PIN as your device will negate the entire purpose of locking the app.
You can even hide installed apps on your Android device for extra security.
Download AppLock from Google Play on your Android device. The app can be downloaded and used free of charge. However, in order to get rid of ads and unlock advanced features, you need to purchase the full version.
When you start the app for the first time, you will be asked to create a master PIN. Enter a four-digit PIN, but make sure it is different from your phone’s unlock PIN. You have to enter the PIN twice to confirm.
When you’ve set up the fingerprint scanner on your device, AppLock asks if you want to lock apps with a fingerprint. Tap on Yes sir or no, depending on your preference.
Tap the + Icon, and then proceed to choose the apps you want to lock. You can lock as many apps as you want. Confirm your selection by tapping + symbolize again.
The first time you lock an app, you need to give AppLock certain permissions. A dialog also opens automatically for this.
Tap on OK and then proceed to give AppLock access to the Access to usage data Permission. Similarly, give the app permission to Appear at the top. Finally, you also need to give the app permission to access your phone’s internal storage.
After granting the necessary permissions, all selected apps will be blocked. Now the next time you try to open a locked app, you’ll be asked to either enter the unlock PIN or to confirm your identity with the fingerprint scanner. You’ll need to enter the unlock PIN or use the fingerprint scanner even when accessing AppLock.
How to block notifications
You can also prevent all notifications from a locked app from appearing on the notification screen. Instead, these apps display a “Notification is blocked” message.
To do this, open AppLock and tap the notification lock icon next to the name of the app you want to lock. The first time you’re doing this, you’ll need to give AppLock notification access. Once done, you will need to enter the AppLock password / pattern or verify your fingerprint before you can view the contents of a locked notification.
With AppLock you can even set different passwords for each locked app. Go to Settings> Multiple Passwords in AppLock and add a new password / PIN / lock according to your requirements.
Lock apps for extra security
Ideally, you should always use a password / PIN lock on your Android device, with the app lock acting as an extra layer of security. That said, locking down apps with sensitive or important data is always a good idea, especially if you can put it at ease with it.
