Xiaomi Redmi smartphones have long proven to be affordable devices with wide functionality, but privacy issues remain relevant for each owner. The built-in MIUI shell offers powerful tools to restrict access to data, allowing you to hide the contents of messengers, gallery or bank customers from prying eyes. Setting a password for a particular application is the first and most effective step to ensure privacy, which does not require the installation of third-party software.
Many users mistakenly believe that data protection requires sophisticated antivirus or paid blocking software. In fact, the Android system in conjunction with the proprietary add-on from Xiaomi has a native mechanism that works at the system level, which ensures that even when you try to remove the application, the protection will not be bypassed, and access to your correspondence will remain closed to the curious.
In this article, we will take a closer look at how to activate the application protection feature on the Redmi 10 model. We will look not only at standard pin code installation methods, but also at more advanced settings, such as hiding icons and using a fingerprint to unlock instantly, and understanding these mechanisms will allow you to fully control access to your digital space.
Preparing the security system before setting up
Before you start locking on individual programs, you need to make sure that the basic level of protection of the device is configured correctly. MIUI requires the basic password to unlock the screen, as this is often used as the default key for secondary protection. If you use a simple pattern lock of four points, the system may suggest to strengthen it to a more complex combination.
It is important to understand that Mi accounts play a key role in restoring access. In case you forget the installed code or key, it is the binding to the manufacturer's cloud service that will allow you to reset security settings without losing data. Make sure that your profile settings indicate the current phone number or email address.
Also worth checking for updates for the system component "Security." Developers regularly release patches that improve the stability of the security modules. To do this, go to the settings menu and find the updates section to make sure that your device is running the current version of the firmware.
⚠️ Note: If you plan to use biometric unlock (fingerprint or face), make sure your biometrics are already added to the system, otherwise the quick app unlock feature will not be available.
Don’t ignore this stage of preparation, as the lack of a backup recovery method can lead to a complete lock of important applications. Unlike unlocking the screen, resetting the password to applications through the Recovery menu will not work – you will need an account or pre-set check questions.
Activation of application protection function in MIUI
The process of enabling lock on Redmi 10 is done through the standard system application, which is preinstalled on all devices of the brand. You do not need to search for hidden menus or enter engineering codes, all the necessary tools are publicly available. First step open the Tools folder on the desktop or find an icon called "Security" (green shield) in the list of all programs.
Inside this app, scroll down to the Application Protection section. Click on this, you'll be taken to the Access Control menu. The system will prompt you to create a password if it hasn't been set before. PIN-code or complex alphanumeric password.
☑️ Pre-activation check
Once you have entered and confirmed your password, the system will suggest setting up the control questions, which is a critical step, because the answers to these questions will allow you to restore access if the main code is lost, select questions that you remember even after a long time, and enter them carefully, observing the register of letters.
Some versions of the MIUI may require permission to access the phone or call history to properly operate the security feature, which is required by the system to identify the owner and prevent conflicts with other security services.
Selection of applications for blocking and access setting
Once you activate the feature successfully, you'll see a list of all programs installed on Redmi 10, and the interface is divided into two tabs: "Secure" and "Unsecured." By default, all applications are in the second category, and you need to manually move the necessary programs to the protected list.
To do this, you just need to click on the switch opposite the desired application, such as WhatsApp, Telegram or Gallery. Once you activate the switch, the system will require you to enter a previously set password to confirm the action, from now on, every time you run the selected application, the credentials request window will appear.
| Type of application | Recommended level of protection | Password request frequency |
|---|---|---|
| Bank clients | High (Password + Biometrics) | Every time you launch. |
| Messengers | Medium (Password/Print) | After 1 minute of downtime |
| Gallery/Photos | High-pitched | Every time you launch. |
| Social media | Low/Mediocre | After 10 minutes of downtime |
It is important to note that you can flexibly adjust the time it takes for the system to request the password again after locking the screen. For banking applications, it is better to set the value "Immediately" or "In 1 minute" to minimize the risks of unauthorized access.
Don’t block system processes like Phone or Messages (SMS) if you’re not sure what the consequences are. Blocking the Phone app can make you unable to accept an incoming call until you enter a password, which in an emergency situation will be extremely uncomfortable.
Using biometrics to quickly unlock
Entering a password every time you need to quickly respond to the messenger can be annoying, so Xiaomi suggests using biometric data. On the Redmi 10 model, a fingerprint scanner is available, built into the on button, which makes the process of unlocking applications as fast and convenient as possible.
To activate this feature, go to the "Application Protection" settings and find "Use your fingerprint." Once you turn on this option, the system will request biometrics instead of entering a pattern lock, which not only speeds up access, but also increases security, because the fingerprint is unique.
⚠️ Note: Biometric unlocking may not work if your finger is wet, dirty, or if you just rebooted your device.
You can also activate Face Unlock in the settings if the MIUI version supports facial recognition software for secondary protection, but it is worth remembering that this method is less reliable than a fingerprint scanner and can be fooled by a quality photo.
For maximum efficiency, it is recommended to combine methods: use the fingerprint for everyday use and keep in mind a complex password in case of failures.
Hiding applications and creating a second space
The application protection feature in MIUI has a hidden potential that not everyone knows about. In addition to simply asking for a password, you can completely hide the icon of the protected application from the desktop, in which case the program disappears from the menu, and you can only find it through a special hidden login in the Security application or through search.
To activate this feature in the application protection menu, click on the settings gear in the upper right corner. Find the Hide Content or Hide Apps switch. Once activated, the system will prompt you to enter a special access code (for example, #1234#), which will open the hidden partition.
How does hidden space work?
The alternative is to use the "Second Space" function, which creates a full-fledged copy of the system inside your phone, which is a more radical method that requires separate setup, but it provides the highest level of data isolation, switching between spaces is like switching between accounts.
Hidden apps are especially important if you hand your phone to your kids for games or your colleagues to show you a presentation, and they don't even know that certain programs are on the device.
Restoring access and solving problems
Despite the convenience, sometimes there are situations when the user forgets the installed code or the system fails. If you forgot the password from the application protection, but you have attached a Mi Account, recovery will take a couple of minutes. On the password input screen, click on the link "Forgot the password?" and the system will send the confirmation code to the associated number or email.
In case the account is also lost, the only option is to completely reset the phone to factory settings, which will delete all data, so regular backup to the Xiaomi Cloud or Google Drive is a mandatory procedure for responsible users.
💡
Save a backup of your security settings in the cloud so that when you switch to a new Xiaomi phone, you don’t reset the protection, but just restore it from the backup.
A common problem is that the application stops asking for a password after the system update, in which case you need to re-enter the Security menu -> Application Protection menu and check if the switch is activated in front of the desired program, sometimes you need to delete and add the application to the protected list again.
Also, consider that some applications can bypass locking if they are running in the background. To avoid this, set the "Block Immediately" or "In 1 Minute" settings in the security settings, rather than "When you exit the application."
