How to block applications on Poco X3: a step-by-step guide

The modern Poco X3 smartphone holds a huge amount of confidential information, from instant messaging to banking applications. Device owners often face the need to hide the contents of individual programs from prying eyes, whether they are curious friends or children. Fortunately, the MIUI shell (and its modification HyperOS) provides powerful built-in tools to solve this problem without installing third-party software.

The process of setting up data protection on Poco X3 does not require deep knowledge in programming or complex manipulation of system files. All the necessary functions are already integrated into the security section and are available immediately after unpacking the device. However, many users simply do not know where to look for the right switches, since the logic of the Xiaomi menu has its own peculiarities. In this article, we will discuss in detail all the ways of setting passwords, including standard methods and hidden system features.

Before you start setting restrictions, it is worth noting that Xiaomi’s protection system works at the core level of the Android operating system.This provides a higher level of reliability compared to conventional launchers. Blocking applications on Poco X3 can be implemented through a pattern lock, a digital code or biometric data such as a fingerprint or facial recognition. The choice of the specific method depends on your personal preferences and the requirements for the speed of unlocking.

Standard function "Application Protection"

The easiest and most effective way to restrict access to content is to use the built-in Application Protection tool, which is part of the Security system application that is preinstalled on every Poco X3, which allows you to selectively password any installed programs, making their content inaccessible without authorization, and when you try to open a secure application, the system will instantly request verification of identity.

To activate this feature, you need to open the phone's settings menu. Search by settings or category list, find Application Protection. If you can't find it right away, go to the App section and select the appropriate tab. The system will prompt you to set a primary password or use biometrics if it's not already configured on the device, which will be the "key" to all your protected data.

Once you have the access code installed, you will see a list of all the installed programs, you will simply need to switch sliders against the applications you want to hide, for example, often block the Gallery, Messages or bank customers, and it is important to understand that once the protection is activated, each run of the selected program will require a password or a fingerprint scan.

⚠️ Warning: Be sure to link your Mi or Google account to recover your password. If you forget the access code and are unable to use biometrics, it will be extremely difficult to restore access to blocked applications without resetting the data.

The security feature on the Poco X3 also allows you to set up automatic locking, so you can choose when the system should request a password: immediately after the application is closed or after a certain downtime has expired, which adds an additional level of convenience, allowing you not to enter the code every time you switch between windows, but keeping the data safe.

Set up biometric unlocking

Using biometrics on the Poco X3 makes it much faster to access secure data. The smartphone has a fingerprint scanner built into the power button and facial recognition. These technologies work in conjunction with the App Lock feature, allowing you to open hidden applications in fractions of a second. To set up, you first need to register your biometric data in the main settings of the system.

Go to the Settings menu and find the Passwords and Security section. This is where you can find the Fingerprint Unlock and Face Unlock. Follow the instructions on the screen to let the system read your data. After successful registration, return to the Application Protection menu. In the upper right corner of the screen, click on the gear icon to open additional settings.

In the security settings menu that opens, find Use your fingerprint or Use your face. Activate the appropriate switches. Now, when you try to open a locked application, Poco X3 will first try to count your finger or face, and only if it fails will it ask you to enter a pattern lock or digital code. This combination of security and comfort is the standard for modern devices.

💡

For maximum unlock speed on the Poco X3, use a side-fingerprint scanner that works faster and more accurately than face-unlocking in bright sunlight.

It is worth noting that biometric data is stored in a secure partition of the memory of the processor and is not transferred to the company’s servers. However, if you change the password to unlock the screen, the system may require re-authorization to access secure applications.

Hiding applications through the Second Profile

A more radical but effective method of hiding data on the Poco X3 is to create a Second Space, which creates a completely isolated environment inside your smartphone that looks like a clean device with its own set of apps, contacts and files, switching between the main and second profiles is instantaneous and protected by a separate password or fingerprint.

To activate Second Space, go to Settings and select Second Space. Press Enable and follow the instructions of the Settings Wizard. You will be asked to create a separate password or set up a special fingerprint that will immediately open the second profile, bypassing the main lock screen, which is the perfect way to hide not just individual applications, but entire groups of data.

In Space Two, you can install copies of social networks, banking apps, or games that you use separately. For a third-party observer who has access to your main screen, the existence of a second profile will be invisible. You can move files and applications between spaces through a special shortcut on your desktop or through the settings menu.

Using Second Space consumes more RAM resources, as two instances of the system actually run. On Poco X3 with its storage capacity, this should not cause problems, but the background operation of a large number of applications in both profiles can affect autonomy.

Using Invisible Mode for Files

Often, the reason you have to block applications is because you want to hide certain files that are stored inside them, like photos or documents. For those cases, MIUI has a Hidden Album or Second Space feature for files. While this doesn't block the application itself, it makes the content inaccessible without a special action.

To use this feature, open the standard Files Explorer or Gallery app. In the settings menu or in the Albums section, find the Hide Album option. Once activated, you will need to swipe your finger from the bottom up the screen and hold it for a few seconds to see the hidden content.

You can move any files to this hidden section. Even if someone gets access to the Gallery or Explorer app, they won't see those files without knowing the secret gesture and password.It's a great way to complement the application lock, providing a double layer of protection for the most sensitive data on your Poco X3.

When cleaning the cache or using aggressive memory optimizers, the system usually ignores the hidden partition, but it is better to recheck the cleaning settings so that important data is not accidentally deleted.

Parental Control and Digital Well-Being

If your goal is to limit your child’s access to certain games or social media on Poco X3, standard password locking may not be enough, because the child may know the code, in which case it’s better to use built-in Digital Well-Being and Parental Control tools, which allow you to not just close the apps, but limit the time you use them.

Go to Settings and select Digital Well-Being and Parental Controls, where you can set timers for specific apps, like setting a 30 minute limit for YouTube or Instagram per day, and after the limit is exhausted, the app will be blocked until the next day. To protect your child from changes, use the Parental Control function, which requires input. PIN-parental code.

You can also create user profiles, you can create a separate Child profile, where you only have apps you have approved, and switching between profiles requires a device administrator password, which is more flexible than a simple lock, because it allows you to control not only the fact of access, but also the duration of use.

⚠️ Attention: Parental controls require a Google account and may not work properly if the device has modified versions of the system services.

Using timers and profiles helps to build healthy digital habits, not only in children but also in adults. The usage statistics provided by the system allow you to analyze how much time you or your loved ones spend on your phone and adjust behavior if necessary. It is a modern approach to security aimed at controlling time, not just access.

Solution and resetting of settings

When using the lock features on Poco X3, users may experience a variety of situations, such as a forgotten password or biometrics failure. If you forget your application protection password, the system will prompt you to answer the check question if you set it when you first set it up, which is the main way to restore access without losing data.

In case the check issue is also forgotten, the only option is to completely reset your phone settings or delete the Security app data, which will result in the removal of all lock settings.To avoid this, regularly update your application protection password and store it in a safe place. Also make sure your Mi Account is active and has access to the Internet, as sometimes recovery is possible through it.

If biometric unlocking is no longer working for secure applications, try removing old fingerprints and writing them back. Sometimes the sensor may “forget” settings when you update the system, and check if the fingerprint function is disabled in the application protection settings themselves, as system updates sometimes reset some resolutions.

Safe Start Mode can be used to diagnose lock problems, although it works specifically on MIUI, most often by simply restarting the device or cleaning the cache of system applications. If the problem persists, check for system updates, as newer firmware versions for Poco X3 often fix security bugs.

💡

Regular update of firmware and the availability of an actual Mi-account is the key to the ability to restore access to blocked data in the case of a forgotten password.
