Protection of personal data becomes a priority for every smartphone owner, especially when the gadget contains confidential information, banking applications or personal correspondence. Owners of brand devices Xiaomi are in an advantageous position, since the proprietary shell MIUI offers a built-in, deeply integrated tool for blocking access to selected apps without the need to install third-party software. This feature, known as “Application Protection,” works at the system level, ensuring high reliability and stability.
Many users mistakenly believe that in order to limit access to instant messengers or the gallery, they need to download suspicious utilities from the store Google Playwhich often contain advertising or collect data. In fact, the algorithm of actions is extremely simple and does not require superuser rights or complex manipulations with the system. Just go to the appropriate section of the security settings and select the list of apps that should be hidden from prying eyes when the screen is unlocked.
In this article we will analyze in detail the entire process of activating protection, consider the nuances of working with different types of locks (pattern, PIN code, fingerprint) and answer frequently asked questions that arise during setup. You will learn how to prevent children from accidentally starting games or hiding financial transactions from prying eyes, using only the standard capabilities of your smartphone.
Preparing to set up application protection
Before you proceed to directly activate the function, you need to make sure that your device is ready to work with security tools Xiaomi. The first step is to check that the operating system version is up to date, since in very old builds MIUI the security menu interface may differ or the function may not work correctly. It is recommended to update your smartphone to the latest available version through the menu Settings → About phone.
The second critical point is the presence of a configured main screen lock. The system will not allow you to set a password for individual applications if the smartphone itself is not protected with at least a simple pattern or PIN code. This is a logical security requirement: if an attacker gains access to the desktop, he can bypass application protection through settings or data reset if the main screen is not locked.
⚠️ Attention: Make sure you remember the screen unlock code. If you forget your Application Protection password, restoring access is only possible by resetting security settings, which will delete data from protected folders, but will not affect the applications themselves.
It is also worth deciding in advance on the type of authentication that will be used. Security system Xiaomi supports several options: pattern key, digital password, mixed password and biometric data. For maximum convenience, it is recommended to use a fingerprint or face unlock in conjunction with a backup digital code.
Activating the “Application Protection” function in MIUI
The process of enabling protection is intuitive, however, the path to the desired menu may vary slightly depending on the version of the shell. In most modern models, you need to open the standard “Security” application, which is preinstalled on all brand devices and has an icon in the form of a green shield. This is the central hub for managing antivirus, memory cleaning and privacy. MIUI 12, 13 and 14 you need to open the standard “Security” application, which is preinstalled on all brand devices and has an icon in the form of a green shield. This is a central hub for managing antivirus, memory cleaning and privacy.
After launching the application, scroll down the list of available tools to the “App Protection” section. If you don't see this option right away, it may be hidden in the additional menu or require initial setup. The first time you click, the system will ask you to come up with a password that will be different from the screen unlock password, although users often set them the same for ease of remembering.
Path to settings: Security → Application protection → EnableAt the password creation stage, you will be asked to bind Mi Account. This is an extremely important step that is often ignored, but it is what allows you to regain access to locked applications if you lose your password. Without linking an account, resetting a forgotten code is only possible through a complete reset of the device to factory settings, which will lead to the loss of all data.
☑️ Check before turning on
Selecting applications to block and setting exceptions
After successfully activating the function, a list of all apps installed on the device will open in front of you. The interface is divided into two tabs: “Protected” and “Unprotected”. By default, all applications are in the second category, and you need to manually move those of them, access to which you want to restrict, to the protected list.
Tap the switch next to the desired application, for example WhatsApp, Telegram, Gallery or a banking application. Immediately after the switch, the system will ask you to enter the previously set password or fingerprint to confirm the action. This ensures that only the owner of the device can change the list of protected software.
| Application type | Protection recommendation | Risk level |
|---|---|---|
| Messengers | Required | High |
| Banking applications | Required | Critical |
| Social networks | By desired | Average |
| Games | For control of children | Low |
| System utilities | Not recommended | Low |
It is important to note that the protection applies not only to launching the application, but also to viewing notifications. In the Application Protection settings, you can enable the function of hiding the contents of notifications. In this case, even if a message comes to the locked screen from Viber, its text will be hidden with asterisks until the password is entered.
Hide the contents of notifications in the protection settings so that even on the lock screen no one sees the text of the message from the protected messenger.
Setting biometric unlocking and delay time
Entering a password every time you open an application can become tedious, so the developers Xiaomi implemented a flexible system for setting the lock time. In the "Application Protection" menu, the "Settings" section is available, where you can select the "Block again" option. Several options are offered here: immediately, after 1 minute, after 10 minutes or 30 minutes after you minimize the application.
Using biometrics significantly speeds up the access process. If your smartphone is configured with a fingerprint scanner or facial recognition, you can allow these methods to be used to unlock protected apps. To do this, in the security settings you need to activate the corresponding toggle switches “Fingerprint unlock” or “Face unlock”.
- 👆 Fingerprint: The fastest and most reliable method, works even in the dark and does not require precise positioning of the face.
- 😎 Face recognition: Convenient when your hands are busy, but may be less reliable in poor lighting or when you are wearing a mask.
- 🔒 Pattern key: A classic method that cannot be faked biometrically, but requires time to enter.
⚠️ Attention: Biometric unlocking only works for logging into the application. To change the protection settings or remove an application from the protected list, the system will always require you to enter the main password.
It is recommended to set the blocking delay to 1 or 10 minutes for frequently used instant messengers, so as not to enter the code every time you reply to a message. For banking applications and galleries, it is better to select the “Immediately” option to ensure the maximum level of privacy when switching between tasks.
What to do if the fingerprint is not read?
If the fingerprint scanner does not work several times in a row, the system will automatically prompt you to enter a backup digital password or pattern. Make sure your finger and scanner are dry and clean. As a last resort, you can use the “Forgot Password” function if your Mi Account is linked.
Hiding applications and working with Second Space
The "Application Protection" function MIUI has another powerful option - the ability to completely hide the application icon from the desktop. When this mode is activated, the app disappears from the general list, and it can only be found through a special gesture in the Security application or through a system search by entering a secret alias. This is an ideal option for those who want not just to protect, but to completely hide the presence of certain software on the device.
For a more radical division of data, there is the “Second Space” function. This is the creation of almost a second independent smartphone inside one device. In the Second Space, you can install separate copies of applications, set up a different password, a different fingerprint, and even a different account Google. Switching between spaces occurs instantly using a fingerprint or password.
Using the Second Space is advisable if you need to completely isolate work applications from personal ones or hide the presence of a whole set of apps from family members. However, it is worth remembering that this function consumes additional resources RAM and may slightly affect the battery life of the device.
Hiding the application icon is an additional level of privacy that works in conjunction with a password: no one will even see the presence of the app until they enter a special access code.
Restoring access and solving common problems
The most common problem that users encounter is a forgotten application protection password. If you linked Mi Account during setup, the solution takes a couple of minutes. On the password entry screen, click on the words “Forgot your password”, after which the system will prompt you to log into your account to reset the code. After successful authorization, you can set a new combination.
If the account has not been linked, the situation becomes more complicated. The only way to reset the password in this case is to clear the Security app data or completely reset the device. Clearing data can be done through the menu Settings → Applications → All applications → Security → Clear, but in new versions MIUI this option is often blocked to protect against unauthorized access.
- 🔄 Reset via Recovery: A complete reset of the device will delete all data, including the security password, but this is a last resort.
- 📞 Xiaomi Support: In some cases, the support service can help if you have the purchase receipt and the box from the device.
- 🛡️ Prevention: Always write down your password in a safe place or use a password manager when setting it up for the first time.
⚠️ Attention: The interface and menu layout may vary slightly depending on the regional firmware (Global, EEA, China) and Android version. If you do not find the described items, use the search in the settings by entering the query “Protection” or “Lock apps”.
Also, users sometimes complain that protection does not work when switching between applications. This is usually due to the blocking time settings. Check to see if it is set to Never or the time interval is too long. In addition, some applications running in the background may not be blocked again until the process is completely completed through the multitasking menu.
If you plan to sell your phone or send it in for repairs, be sure to disable application protection and log out of your Mi Account so as not to block the device for the new owner.
Frequently asked questions (FAQ)
Is it possible to set different passwords for different applications?
Unfortunately, the standard “Application Protection” function MIUI involves using one common password for all selected apps. It is impossible to divide them into groups with different codes using the system. To implement such a scheme, you will need to use third-party locker applications, but this may reduce the overall security of the device.
Does application protection affect the operation of notifications and calls?
No, protection does not block incoming calls and notifications. You will see the very fact of receiving a call or message in the notification shade. However, if the hide content option is enabled, the message text will not appear until the app is unlocked. Calls go through unhindered, since the blocking is removed automatically when a call is accepted through the system interface.
What will happen to the data in the application if I remove it from the protected list?
All data inside the application will be saved in full. Removing it from the protection list only removes the launch restriction. You will be able to open the app as usual, without entering a password. This is a reversible action, and you can add the application back to the protected list at any time.
Does application protection work if the phone is turned off?
Application protection is activated only after the first unlock of the smartphone screen after turning it on. Until the device is unlocked with a master password or biometrics, any applications cannot be launched. Thus, application protection is the second line of defense after the main screen lock.
Is it possible to bypass application protection through safe mode?
In modern versions MIUI entering safe mode does not disable the application protection function. When booting into Safe Mode, the system will still require you to enter a password to access protected apps. This is done to prevent attackers who have gained physical access to the device from bypassing the protection.
