Ways to Add Password/Fingerprint Lock on Apps

You can add a password lock on your apps by two methods mainly. You can lock individual apps by using third-party apps that are made for this purpose only and also offer some added features. Here are some apps that you can use to lock your apps.

1. AppLock

The most popular and easy-to-use app for locking other apps is AppLock. There are many apps available with the same name that can be downloaded for free from the Google Play Store and we have given a link to one of the best apps here. Here’s how to use this app:

  1. Download the AppLock app on your phone.

2. Now, open the app, and when prompted input a unlock pattern to lock apps. Make sure it’s not the same pattern you use to lock your phone.

3. Tap on “Agree and Start” and then give AppLock permission to use “usage access” of your phone and “display over other apps” when prompted.

4. Now, you will see a list of all apps installed on your phone. Select an app that you want to lock with the password you’ve created in AppLock and tap the “Lock” icon.

That’s it. You’ll be notified that the app was successfully locked. Try to open that app to confirm if it locked with a passcode.

We like AppLock because it offers some other features in addition to locking individual apps, such as a cleaner and booster to free up storage space and boost performance on your phone.

2. Norton App Lock

Norton App Lock is another useful tool for protecting apps and private files on your phone. The app is free to download and supports Android 4.1 and above. Here’s how to use the app to lock your apps on Android:

1. Download and install Norton App Lock on your phone.


2. Now open it and select an Unlock Pattern or Passcode.

3. When prompted for Accessibility, tap on Setup and give it Accessibility permission.

4. After that, tap on Choose Google Account and confirm your email.

5. Give permission to “Allow display over other apps” and enable the toggle

6. Now on the apps page, select the yellow lock icon in the upper-right corner and then select the lock next to the apps you want to protect.

Once apps are locked, you can check by opening them and these apps will ask for the passcode you created earlier.

3. AppLock – Fingerprint

AppLock – Fingerprint is an AppLocker that locks and protects apps using a password or pattern and fingerprints. You can lock Facebook, Whatsapp, Gallery apps with a password and a fingerprint and prevent the apps from being exposed by a snooper. The app also offers a feature that can catch intruders by taking a picture.

1. Download and install AppLock- Fingerprint on your phone.


2. After that, when you open the app, it will ask you to set up a master PIN that will be used to unlock the apps. You will also be asked to use your phone’s fingerprint lock.

3. Now, the app will ask permission for “Usage Access” and “Display over other apps”. Enable the toggles when prompted and then return to the app.

4. In the app, you will see your installed apps under the Apps tab. Select the apps you want to lock and then tap on the “+” icon to add these apps to the lock list.

That’s it. Now, your apps will be locked and you can check those by opening the apps and it will ask for a PIN or fingerprint.

4. Screen Pinning

There is a feature in Android phones dubbed as Screen Pinning that lets you lock your phone’s screen to a particular app. So when you give your phone to anyone and if that person attempts to leave that app or close it, your phone will be locked.

Here’s how you can enable this feature on your phone:

1. Go to Settings and then Security and choose Advanced. Now scroll down to Screen pinning. (In older Android versions, it’ll be under Lock screen & security). 

2. Enable the Screen Pinning toggle On.

3. Now, open the app that you want to pin on your home screen.

4. Then open the app switcher or the Recent apps screen.

5. Swipe up on the Recent app’s card and tap the app icon and you will see the Pin icon. Tap on it.

That’s it! Your phone will now be licked to that one app only.

5. Hide Apps or Secure Folder

Samsung and some other companies that have their own UI offer a feature to hide apps that lets you move apps into a lockable or hidden folder. You can lock that folder with a passcode, a PIN, or even your fingerprint. Secure Folder or Hide Apps from your app screen can be accessed from the Home screen settings.

So, if you some of your app that might have your personal data that you don’t want others to see, here’s how you can hide it in a secure folder on Samsung phones:

  1. Open Home Screen Settings by tap and hold anywhere on home screen.

2. Now scroll down and you will find the Hide apps option.

3. Tap on it and then select apps that you want to hide from the app screen. Lastly, tap on Done and That’s it!

Those apps will be hidden from the home screen and app screen as well. You only can access them and also unhide them anytime by following the same steps as above.

As you can see, these are a few ways to add a password lock on apps on your Android phone. If you have a secure folder or hide files option in your phone’s Settings, use it. Otherwise, we recommend using third-party apps, as these can come with other features.
