How to lock apps with passwords

If you want to lock applications with a password on Android, to prevent someone from accessing them, we show you all the ways to do it.

Sometimes we leave our phone to someone so that they can use it. When this happens, we don’t want this person to go into some applications and see what it contains, such as reading our chats on WhatsApp or viewing photos in the gallery, for example. In these situations, we can lock applications with a password on Android.

It is a method that prevents someone from accessing that application without authorization, unless they know the password. There are several methods to lock applications with a password on our Android phone.

How to lock an application with a password from the phone settings

Many levels of customization in Android natively have a feature that allows you to lock applications with a password. In this way, in the settings we will create a lock password or use the fingerprint, as well as choose which applications we want to lock.

One of the advantages of this method is that you don’t have to install anything, other than being able to choose the applications you want to block, because it’s likely not all of them. The steps to follow may vary depending on the model:

  • Open your phone settings.
  • Choose Privacy and Security.
  • Go to the Application Lock section.
  • Create a four-digit PIN.
  • Choose the apps you want to block.
  • In the settings (gear icon) you can enable fingerprint lock.

Depending on your phone model, some of these options may or may not be available. For example, you may not be able to use your fingerprint on your phone. This will depend on the level of customization used, but it is usually normal that the ability to lock applications with a password already exists natively.

Enter a password from the application itself

This is an option that some Android applications have. Telegram, for example, natively has the ability to lock it with a password, or even using the fingerprint. Another very popular application on Android, WhatsApp, has this fingerprint lock activation feature.

It is not something too common on Android, but there are applications that have the ability to lock via password natively. Then we can check the settings of our applications, to check if this is a function that exists or not.

It is also possible that there are applications where it is not possible to use a password, but we can use the fingerprint, if this option interests some.

App to lock apps with password on Android

The third option we can turn to is to use third-party applications. There are applications that are meant to lock other applications on Android with a password.

This will allow us to use an application to determine which other applications on our phone are locked by passwords or even fingerprints. It’s a pretty handy option, and there are some cool apps:

App Locker

App Locker is one of the most popular in its sector, which in a simple way will allow us to password lock other applications on Android. This application stands out for its simplicity of use, thanks to a very clean and easy to use interface. The first thing we need to do is establish an access template or use your fingerprint to log into this application.

In the application we find a list of all the applications we have installed. It will be in this list where we can choose which of the applications we have installed will be blocked using a password. We can select everyone we want to protect in this way. In the application settings we can choose if we want to enter a PIN or if we want to use the fingerprint or said model.

App Locker is very easy to use, as well as being an ideal option to lock password applications on Android. It can be downloaded for free from the Play Store. Inside there are announcements, in addition to purchases, because there is a Pro version of the application, which offers us some additional functions. This version costs 3.69 euros.

Lock: AppLock

This second option serves the same purpose as the previous application, as well as having a similar operation. It will allow us to lock applications on Android with a password. Although it also has support to do it using your fingerprint, so you can choose the option that is most convenient for users in any case. In addition, it also allows us to take a photo if someone tries to break into our phone.

The interface of this application is easy to use. Inside we find the App Lock section, where we find the applications installed on the phone. Next to each of them there is a switch that we can activate, to use the password lock on them.

Downloading App Lock on Android is free. Inside the application there are some ads, although not annoying. There is a paid version, priced at € 4.89, which allows you to remove the ads and have access to some additional functions. If you’re looking to protect apps with a password or your fingerprint, the free version suits it.
