A modern smartphone stores a huge amount of confidential information, from personal correspondence to banking data, so the issue of protecting privacy becomes critically important for every owner. Smartphones in the line Redmi from the company Xiaomi are equipped with a powerful set of security tools, which are often hidden deep in the system settings and are not obvious to the average user. Setting up individual access to specific apps allows you to prevent unauthorized viewing of your content, even if the device is unlocked.
Model owners Redmi 10 often face the need to limit access to the gallery, instant messengers or financial applications for family members or colleagues. The built-in shell MIUI offers several protection scenarios: from a simple application blocker to creating a completely isolated space with a separate password. Understanding the architecture of these functions will help you choose the most appropriate method of ensuring digital hygiene.
In this article we will analyze in detail all the available methods for setting passwords, the features of biometric protection and the nuances of setting restrictions in the ecosystem. Xiaomi. You will learn how to activate a hidden profile, set up different fingerprints for different tasks, and what pitfalls can be encountered in the process of setting up the security system of your device.
Built-in application blocker in MIUI
The easiest and most effective way to protect individual apps on Redmi 10 is to use the standard “Application Protection” functionality. This tool is integrated directly into the Security system application, which is preinstalled on all brand devices. To activate the function, you do not need to install third-party software, which guarantees stable operation and no conflicts with the system.
To start setting up, you need to open the application Security and scroll down the menu to the “Application protection” section. When you first start, the system will prompt you to set a unique password or pattern, which will differ from the main screen unlock code. Important to remember this code, since it will be requested every time you attempt to enter protected apps.
After setting the password, you will be prompted to link your account Mi Account to be able to restore access if the code is lost. Next, a list of all installed apps will open, where you can switch the toggle switches opposite those applications to which you want to restrict access. The system will automatically apply the settings, and the next time you launch the selected software, you will be prompted to enter a password or scan your fingerprint.
⚠️ Attention: If you forget the application protection password and do not link your Mi account, the only way to reset will be to completely reset the device to factory settings, which will lead to the loss of all data.
The blocker functionality allows you to flexibly configure exceptions. For example, you can allow access to certain apps without entering a password for 15 minutes after the main screen is unlocked. This is convenient for frequently used apps, but reduces the level of security when transferring the phone to another person.
Use a complex pattern instead of a simple PIN code to protect applications, as it is much more difficult to spy on from the outside when entering.
Activating the Second Space for complete isolation
For users who require the maximum level of privacy, The shell MIUI offers a “Second Space” feature. This technology creates a completely isolated environment inside the smartphone, which works as a separate user profile with its own applications, files and settings. Data in the main and second spaces do not intersect and are not visible to each other.
Activation of the Second space is carried out through the menu Settings → Accessibility → Second space. During the setup process, the system will prompt you to create a separate password or fingerprint to enter this mode. The uniqueness of the method is that you can assign different fingerprints to enter the main and second space.
For example, by placing your right thumb, you will be taken to your personal profile with all the basic data, and by placing your left index finger, you will immediately find yourself in a hidden space with secret applications. This allows you to hide the very fact of the presence of confidential content on the device, since the lock screen will unlock to the desired profile without any questions.
- 🔒 Complete file isolation: photos and documents in the second space are not visible in the main profile gallery.
- 📱 Independent installation of applications: you can install a second copy of the messenger or social network with another account.
- 👆 Biometric switching: instant login to the desired profile using a fingerprint without entering passwords.
- 🚫 Hiding icons: applications installed in the second space are not displayed in the general list of apps.
Switching between spaces can be done not only through the lock screen, but also through a special shortcut on the desktop or in the notification shade. This is convenient if you use the same finger to unlock, but want to quickly change the context of using your smartphone.
Setting up biometric security and fingerprints
Using biometric data on Redmi 10 greatly simplifies the authorization process in protected applications. The fingerprint scanner located on the side of the device is fast and accurate, allowing you to open locked apps in a split second. However, for this function to work correctly, you must correctly configure the priorities in the security system.
In the application protection settings, there is an option “Unlock with a fingerprint”. Make sure this switch is enabled. If you have multiple fingerprints registered, the system will accept any of them for unlocking unless Second Space with different fingers is configured. To increase security, it is recommended to regularly update your fingerprint data in the menu Settings → Passwords and security → Fingerprints.
It is worth noting that biometrics does not completely replace the password, but only supplements it. After rebooting the device or in the event of several unsuccessful scanning attempts, the system will still require you to enter a digital or pattern lock. Reliability of protection directly depends on the complexity of this backup password.
⚠️ Attention: Biometric data is stored in a secure processor module, but in the event of a serious failure of the scanner logging into protected applications will only be possible by entering the main password.
The face unlock function is also available, however on the model Redmi 10 it is implemented in software through the front camera and is less secure than a fingerprint scanner. It is not recommended to use face unlock to protect banking applications or personal photos, as it can be deceived using a high-quality photo.
☑️ Checking biometric settings
Access restrictions through Digital Balance
In addition to classic password protection, in the Android-based system MIUI there is a Digital Wellbeing tool that allows you to limit the time you use applications and set rest periods. Although this feature is initially intended for self-monitoring, it can be adapted to create temporary blocks from access to certain content.
In the menu Settings → Digital Balance you can set a timer for specific applications. When the time limit expires, the application icon turns gray, and it cannot be launched without changing the settings or entering the control password. This method is useful for parents who want to limit children's access to games or social networks at certain times of the day.
Focus mode allows you to temporarily block distracting applications, creating a list of allowed apps for a certain period. Activation of this mode requires confirmation, which complicates the accidental or unauthorized launch of blocked software. However, it is worth understanding that this is not full-fledged password protection, but rather a time management tool.
| Restriction type | Protection level | Bypass difficulty | Purpose |
|---|---|---|---|
| Application protection | High | Requires password/fingerprint | Data confidentiality |
| Second space | Maximum | Requires separate login | Full profile isolation |
| Digital balance | Low | Can be reset in settings | Screen time control |
| Notification blocking | Medium | Hide content | View protection from the outside |
Using “Digital Balance” in conjunction with application protection has a double effect: you not only hide the contents of the app behind a password, but also limit the time that can be spent inside it. This is especially true for dealing with dependencies or organizing your workflow.
Secret function for hiding applications
In some versions of MIUI, it is possible to completely hide application icons from the desktop. To do this, you need to pinch with two fingers on the main screen, select “Hidden applications” and add the necessary apps. They will only be accessible through a special code in the dialer or through settings.
Managing notifications and content previews
Even if the application itself is password protected, confidential information can leak through pop-up notifications on the lock screen. An attacker or a curious acquaintance can read the text of the message or see the subject of the letter without entering the app. Therefore, setting up notification privacy is a mandatory step in comprehensive protection.
Go to section Settings → Notifications and status bar → Lock screen. Here it is recommended to select the option “Do not show notifications” or “Show notifications but hide content”. In the latter case, you will only see the name of the application, but the message text will be replaced with asterisks or the “Hidden Content” item.
For more detailed settings, you can go to the parameters of each specific application through the menu Settings → Notifications → [Application name]. Disable the “On lock screen” option if you want notifications from this service to come only after your smartphone is completely unlocked. This is especially important for messengers like Telegram or WhatsApp.
Do not forget that some applications have their own internal privacy settings. For example, in the chat settings you can enable hiding the text of messages in the notification curtain, regardless of the Android system settings. Double check parameters both in the system and within the application guarantee maximum secrecy.
⚠️ Attention: The settings interface may vary slightly depending on the version of MIUI (12, 13, 14). If you do not find the specified item, use the search in the settings by entering the keyword “Notifications.”
Comprehensive protection consists not only of a login password, but also of properly setting the display of notifications on the locked screen.
Solving common problems and restoring access
In the process of using security functions, users may encounter a number of technical difficulties, such as a forgotten password, malfunctions of the fingerprint scanner, or the disappearance of the security icon. Understanding access recovery algorithms will help you avoid panic and loss of important data.
If you have forgotten your application protection password, the system will offer to restore it through the linked one. Mi Account. To do this, you need to enter the wrong code several times, after which the “Forgot your password?” link will appear. Follow the on-screen instructions to reset via the email or phone number specified in your profile.
If the fingerprint scanner no longer recognizes your finger, try cleaning the surface of the sensor and your hand from moisture or grease. Also check if your biometric settings have changed after the system update. Sometimes you need to re-delete the fingerprint and register it again for the application protection function to work correctly.
- 🔄 Reset settings: If all else fails, you can clear the Security application data through the settings menu, but this will delete all installed security passwords.
- 🔑 Backup: Regularly back up important data in in the cloud, so that if you reset your password, you don’t lose information.
- 🛡️ System update: Keep an eye on MIUI updates, as new patches often fix errors in security modules.
Remember that the security of your device is in your hands. Regularly changing passwords and paying close attention to access settings will help keep your personal data intact even if you lose your phone or third parties gain access to the unlocked screen.
Write down a complex application protection password in a safe place (for example, in a paper notepad) that is not stored with your smartphone to avoid a situation of complete locking.
You can Is it possible to set different passwords for different applications on Redmi 10?
No, the built-in “App Protection” feature uses a single password or pattern for all selected apps. To separate access with different passwords, you need to use the “Second Space” function, where you can set independent security parameters.
What happens to the data in the application if I remove the protection?
Disabling the application protection function does not delete the data itself, photos or correspondence within the apps. Only the requirement to enter a password at startup is removed. All files and settings remain completely safe.
Does application protection work if the phone is turned off?
Application protection is only active when the operating system is running. When the phone is turned off, access to data is physically impossible. However, after turning on and before entering the main screen unlock password, protected applications also remain inaccessible.
Is it possible to bypass application protection through safe mode?
In standard MIUI firmware, entering safe mode does not disable application protection. A password or fingerprint request will appear even in this mode, since the security module is integrated at the system level.
How to hide the “Security” application itself from the desktop?
It is impossible to completely hide the “Security” system application, since it is necessary for the phone to function. However, you can remove its shortcut from the home screen by moving it to a folder or to the menu of all applications, so as not to draw unnecessary attention to the protection tool.
