Xiaomi’s current smartphones contain a vast amount of personal information, from instant messaging to photos and banking apps. Owners of devices with MIUI shells and the new HyperOS often wonder how to securely hide access to specific programs from prying eyes. Fortunately, the company’s engineers have implemented a powerful built-in security mechanism that does not require the installation of additional software.
The locking of applications on Xiaomi works at the system level, which guarantees high stability and the inability to bypass the protection in a simple way. PIN-This allows you to instantly open secure programs to authorized users and block access to all other users.
In this article, we will discuss all the nuances of setting up the application protection function. We will look at standard methods, features of work in different versions of firmware, and also discuss what to do if the desired menu item is not located. The security of your data is a priority, and the correct use of system tools is the first step to solving it.
Why You Need Personal Program Protection
Using a smartphone in public places or handing over a gadget to family members to make a call poses potential data leak risks. Even if the main screen is unlocked, internal navigation can lead a curious user directly to your personal chats or gallery.
This is especially true for parents who want to restrict their children’s access to certain content or in-game purchases, and is an indispensable tool to protect privacy when repairing a phone or when you give a colleague a phone so they can only view one specific information without access to everything else.
- 🔒 Protecting banking applications from accidental or malicious access by third parties.
- 👶 Time control and children’s access to entertainment and social media.
- 📸 Keeping private photos and correspondence when using the phone by others.
⚠️ Note: Standard application locking does not encrypt data inside them. If an attacker extracts a memory card or gains access to the file system through debugging, the data can be copied.
It's important to understand the difference between locking your phone completely and protecting individual labels, one that locks you off the entire system, the other that allows you to use your device as you normally would, leaving your "secret locker" closed, which strikes a balance between usability and privacy.
Standard settings through the security menu
The main method of activating protection is built directly into the system application "Security". This tool is pre-installed on all smartphones Redmi, Poco and Xiaomi. To start, you need to find an icon called "Security" on your desktop or in the Tools folder.
Once you start the app, scroll down to the "Application Protection" section. If you see this, your firmware version supports native function. When you first run it, the system will prompt you to create a password. You can choose a pattern lock, a digital key. PIN-code.
☑️ Preparation for the installation of protection
Once you set the password, you'll be asked to link your Mi Account, which is a critical step, because it's through your account that you can restore access if you forget your lock password, and without the binding, recovery is almost impossible without a complete data reset.
Then you'll see a list of all the programs you've installed, and you'll just have to switch switch switches against the apps you want to hide, and then every time you run the program, the system will ask for proof of identity.
Alternative methods and hidden menus
In some regions or global firmware versions, the "Application Protection" option may be hidden or renamed. If you don't find it in the "Security" app, try searching by settings. Click on the system settings gear and search for "Protection" or "App lock."
Sometimes the feature can be blocked by a carrier or regional restrictions, in which cases users often resort to changing the region in their phone settings. Switching to India or China will often unlock additional system features, including advanced security settings.
- 🌏 Change of region in settings (Settings) → Advanced settings → Region).
- 🔍 Using a Global Search for Phone Settings.
- 📱 Install system updates that can return functionality.
It’s worth noting that third-party launchers can conflict with the standard lock system. If you’re using a custom desktop shell, make sure it has the necessary permissions to work with system security features.
What if the item disappeared after the update?
Using biometrics for quick access
Entering a password every time you open a messenger can be tedious. Xiaomi’s modern smartphones allow you to use biometric data to unlock secure applications, which greatly speeds up the process and increases usability.
To activate this function, go to the application protection settings (via the "Security" app) and find "Use fingerprint" or "Use face unlock." The system will require confirmation of your primary security password.
Once you turn on this option, you don't have to type the code manually, just put your finger on the scanner or look at the front camera, and the app opens, and it works even if the main screen of the phone is already unlocked.
💡
Use different fingers to unlock your phone and apps if you want to be able to quickly open a secure program, even when the phone is lying on the table unlocked.
It's important to keep in mind that biometrics only works if you have at least one fingerprint or face registered in your system, and if you delete all the biometrics, the function will automatically shut down, and you can only access the applications again through a password.
Comparison of data protection methods
The choice of security method depends on your needs and device model, and the table below compares standard application locking with the “Second Space” mode, which is also often used to hide data.
| Parameter | Application protection | Second space | Hiding applications |
|---|---|---|---|
| Level of access | Requires a password at launch | Separate password system | Hiding the icon from the menu |
| Convenience | High (fast access) | Medium (needs to be accessed in profile) | High (hidden entrance) |
| Visibility. | Icon visible, need password | Profile switch visible | The icon is completely hidden. |
| Resources | Minimum | High (copy of the system) | Minimum |
As you can see from the table, standard application locking is the middle ground between security and convenience. It doesn't hide the fact that a program exists, but it protects its contents. Second Space mode creates a completely isolated environment that is useful for separating work and personal life.
The Hiding Apps feature (not available on all models) works differently: it removes the icon from the menu, and you can only run the program through a special set of numbers in the "caller," which provides stealth, but less protection if the attacker knows that such a feature exists.
Addressing problems and restoring access
The most common problem users face is a forgotten password. If you haven't tied your Mi Account when you set up, it's going to be extremely difficult to restore access to blocked apps. Xiaomi's security system doesn't have a back door to bypass your password.
If you're tied to your account, if you have a few incorrect password inputs, you'll see a "Forgot Password" button on your screen, and if you click on it and you enter your Mi Account, you can reset the application protection code, and then you'll save all the settings, but the password will change.
⚠️ Note: If you reset your password through your account, your browsing history in some secure applications (e.g., in incognito mode within the security) may be lost.
In rare cases, after updating the firmware, the security settings may fly, in which case you need to re-activate the Security application. All previously selected applications will likely have to be re-marked.
💡
Always link your Mi Account to the application protection function – this is the only way to restore access without losing data in the case of a forgotten password.
