How to set a password on the Android app

How to set a password on the Android app

Modern phones are characterized by a high level of security and safety of personal data. This manifests itself in the installation of high-quality fingerprint scanners, as well as the development of special software that can protect the device from the hands of intruders. But sometimes such means of protection are not enough, especially when you need to temporarily pass your smartphone to a relative or a friend. Because of curiosity, a friend can enter some important program, such as messenger. To avoid this, let's figure out how to put a password on the Android app and what you need to do.

How can this be done

Some users have come up with the desire to set a password for important applications on their own. But after visiting certain sections of the settings and not finding the necessary item, the desire to secure your personal data disappears abruptly. In fact, you can set a graphical key or password to the program either through the built-in system features or through third-party utilities.

However, you should understand that smartphones running "bare" Android do not have this feature by default. That is why such devices have to download additional applications from Google Play.

You can use the built-in functionality to set a password on apps on Xiaomi, Meizu, Huawei, Honor and Asus phones. The following instructions are suitable for smartphones that run on Android 6, 7, 8, 9 and higher.

Set a common password for all applications

The decision to set a common password for all applications is the most correct, because it allows you to avoid having to remember a large number of codes. However, this option has a significant disadvantage - a low level of security. By learning the PIN from one utility, another person will be able to apply it to all installed applications. So, here are the ways both using the built-in functionality of the system and using third-party software.

On the Xiaomi phone

You probably know that the manufacturer installs MIUI firmware on Xiaomi smartphones, based on the Android operating system. This shell is characterized by simplicity and ease of use, so it is not surprising that it has built-in by default the ability to set a password for programs. It's easy to activate the necessary protection, but for clarity we recommend using the step-by-step instructions:

  1. Open the settings.
  2. Go to "Application protection".
  3. Check the checkboxes next to the programs for which you want to activate protection. And then click the button "Set Password".
  4. Set a strong graphical key by entering it twice. By the way, if you want to set a numeric code, click on the line "Method of protection"and select the desired option.

This completes the installation of the application password. If you wish, you can link the graphic key to your Mi account, which will allow you to restore it in case of loss.

On a Meizu phone

Recently, devices from the company Meizu began to lose popularity, but their smartphones are still used by a large number of people. The manufacturer also did not merge with the gray mass, and installed on its phones proprietary firmware Flyme. About her they say contradictory things, but built-in protection applications developers provided. To activate it, we recommend using the detailed instructions below:

  1. Open the settings.
  2. Go to "Fingerprints and security".
  3. Go to the subcategory "Application protection"
  4. Move the slider to the right next to the line "Application protection". And now at the bottom of the screen you can see the programs that you can secure.
  5. Check the desired applications and set a password or a graphic key.

With these simple actions, we were able to protect important data in the applications from unauthorized people.

On Huawei and Honor phones

Huawei and Xiaomi are direct competitors, as they offer quality smartphones at affordable prices. A few years ago, a major manufacturer introduced a separate brand called Honor, designed for the younger population. All Huawei and Honor phones run the Android operating system, as well as EMUI branded firmware. It's not hard to guess that it also features the ability to set passwords for applications. How to do this is described in detail in the following instruction:

  1. Open the settings.
  2. Go to "Security and privacy".
  3. Click on "Application blocking".
  4. Create a security code and select the programs for which you want to activate protection.

Now, when you try to open a locked application, the system will ask you to enter a password that only you know. If you want to unprotect an application, follow the instructions in reverse order.

Note that you can use fingerprint unlocking instead of entering a PIN or an ID key.

Using third-party applications

It's clear that not every phone has a built-in tool that allows you to set a password for apps. But it can always be added by installing an additional program from Google Play. Just about the highest quality utilities we will describe in detail further on.
