Protecting personal data on a Xiaomi smartphone is a task that many users put off "for later" until it's too late. Have you ever given a phone to friends to show a photo but worried they'd accidentally open your messages or a banking app? Or maybe you have kids who like to play games on your Redmi, at the risk of clicking on a browser ad or changing settings? Password blocking apps solves these problems once and for all.
In this article, we will analyze all available ways to protect applications on Xiaomi devices, POCO Redmi β from standard functions MIUI You'll learn how to set up locks for individual programs, why some methods don't work on all models, and what to do if you suddenly stop asking for a password, and how to get around restrictions if you forget the access code.
1. the built-in function "Blocking applications" in MIUI: step-by-step
The most obvious and safe way is to use the built-in lock function that is in the firmware. MIUI Since version 8, many users don't even know it exists, because it's disabled by default.
The first thing to do is make sure that your device has a screen unlock password installed (PIN, Without this, the application lock function will not appear on the menu. If the password is not available, the system will prompt you to create it when you first try to turn on the protection.
Now we move on to the settings:
- Open the Settings β Applications.
- Select Application Lock (on some models it may be called Application Protection or Privacy).
- Enter your current screen unlock password.
- In the list of applications, tick the ones you want to block (for example, WhatsApp, SberBank Online, Gallery).
- Press Ready and confirm the action.
After that, every time you open a locked application, the system will require you to enter a password, fingerprint or face scan (depending on the settings of unlocking the screen). If the program is on SD-Card, the lock may not work.
Is there a password for unlocking the screen?
Is firmware updated? MIUI last-minute?
Is there enough space in your memory?
Are there any third-party launchers (they may conflict with the function)-->
2.Why can the application lock function be absent?
Some Xiaomi users are facing a problem: there is simply no βBlock Appsβ option in the settings, and there may be several reasons for this, and most of them are easily fixed.
First, regional firmware, on devices with global or European (EEA) version MIUI This feature is usually available, and on Chinese (China) or Indian (India) firmware it is often removed "as unnecessary"; the solution is to reflash the phone to the global version (but this voids the warranty!).
Second, the outdated version MIUI. On old firmware (below) MIUI 8) Application locking is implemented differently or not at all. Update the system through Settings β The phone. β Updating the system.
The third reason is that there's no screen password, and as we mentioned earlier, without it, the function simply doesn't activate, and also check if the settings are hidden because of the Children's Mode or the Guest Mode.
| Reason for lack of function | How to check | Decision |
|---|---|---|
| Regional firmware (China/India) | View the version in Settings β The phone. β Version. MIUI | Refuse to Global/EEA |
| Outdated. MIUI (below 8th) | Check the version in the same settings | Update the system |
| No screen unlock password | Try to set up PIN In Settings β Lock screen | Create a password |
| Hidden by security settings | Check the modes in Settings β Special facilities | Disable guest/child mode |

If you don't want to flash your phone, but you need to lock it, use third-party apps in the next section. They work on any firmware.
