How to put a password on Xiaomi applications: step-by-step instructions

A modern smartphone stores a huge amount of confidential information that should not be open to prying eyes. Owners of Xiaomi, Redmi and POCO devices often wonder how to restrict access to specific programs without blocking the entire screen of the gadget. The application protection feature in the shell of MIUI or HyperOS allows you to create a reliable barrier between your personal data and curious acquaintances.

Unlike standard screen locking, this tool works selectively, requiring additional proof of identity when running selected programs, especially for instant messengers, banking services and photo gallery, and is built into the system layer of security, ensuring stable operation without the need to install third-party software.

In this guide, we will take a closer look at how you set your restrictions, how you can work with different firmware versions, and how you can learn about hidden privacy features. You will learn not only to set passwords, but also to set your security settings correctly to avoid the possibility of circumventing security.

Preparation for system security setting

Before you start locking directly, you need to make sure that the system has a basic method of unlocking the device. Application protection can not work in a vacuum, it requires a basic access key that will be used by default. If you have not previously installed a pattern lock, PIN-a code or fingerprint to log in to the system, this will need to be done first.

The Android security mechanism in conjunction with MIUI add-ons requires at least one active authentication method, which can be biometrics or digital code. The lack of basic security makes it impossible to create additional layers of security for individual software components.

⚠️ Warning: If you forget the main unlock password, it will be impossible to restore access to secure applications without completely resetting the device.

It is also worth checking for updates for the system component Security, which is often the module that manages access rights, and an outdated version of the component may not contain current features or have vulnerabilities that have been patched in newer releases.

Activation of protection for selected programs

The process of enabling access restriction in Xiaomi shells is unified, but the path to it may vary slightly depending on the version of the interface. The main management tool is the built-in Security app, which has a green icon with a shield, and this is where all the main security tools of the device are concentrated.

To get started, you need to open the application and find the Application Protection section. In some firmware versions, this item may be hidden in the Tools menu or displayed on the main screen of the system utilities folder. Once you log in, the system will ask you to come up with a unique password for this particular feature, which may differ from the screen unlock password.

Once you set your password, you'll be asked to select the apps you want to protect, the list contains all the programs you've installed, and you can activate the switches opposite the ones you want, and it's recommended that you turn on protection right away to:

• 📱 Messengers (WhatsApp, Telegram, Viber)
• 🏦 Banking applications and financial services
• 📸 Galleries and cloud storage
• 📞 Call and contact log

It is important to note that once the protection is activated, a password window or fingerprint request will appear every time you run the selected program, which provides reliable access control even if the phone is already unlocked by the owner.

💡

Use different passwords to unlock your screen and to protect your apps to increase the overall security level of your digital life.

Using biometrics for quick access

Entering a password every time you open a messenger can be tedious, so the system suggests using biometrics. A fingerprint scanner or facial recognition system allows you to instantly confirm entry to secure areas, which not only speeds up the process, but also makes using the lock function more comfortable in everyday life.

To activate this feature, you need to go to the application protection settings and find the item “Use fingerprint” or “Use face unlock.” If biometric data is not already entered into the device memory, the system will prompt you to add them. Modern smartphones Redmi and POCO are equipped with fast and accurate sensors that read a finger in a fraction of a second.

Biometrics is a convenient but not absolute method of protection, and for security reasons, the system may periodically request the entry of a master password, especially after a device has been restarted or after a long period of inactivity, a standard practice of operating system-level encryption.

Set up a hidden space for maximum privacy

For users who need a higher-than-standard level of privacy, MIUI has a Hidden Space feature in its shell, which is not just a password for login, but a full-fledged second environment inside the smartphone. Apps installed in hidden space are completely invisible in normal operation and do not appear in the installed program lists.

To activate this feature, you need to go to the application protection settings and select the option “Hide the applications”, where you can select programs that should disappear from the desktop, you need to enter a special password or use a special gesture to access them, such as swiping your finger on the lock screen with two fingers.

Inside the hidden space, you can create a separate set of applications, with your own accounts and data, which allows you to, for example, have two different social media accounts or completely isolate personal photos from the main stream of media files, in which case the data is isolated at the file system level.

⚠️ Note: When you reset your phone settings to factory settings, all data from the hidden space will be permanently deleted unless you back up separately.

Using hidden space requires care, as it is easier to forget the password from it than from the main lock, due to the rarity of use, it is recommended to periodically check the availability of important files located in this area.

Typical Access Problems Solving

During operation, users may encounter situations where the security system behaves unpredictable, for example, the application may not ask for a password when you start, or, conversely, the request may appear too often, most often due to the power saving settings or the peculiarities of the background processes in Android.

If the security stops working, check to see if the application you blocked has been updated, sometimes after a software update, access rights may be reset and the function needs to be activated again, and make sure that the battery settings for the Security app are not limited to background activity.

Another common problem is forgetting your password. Unlike a Google account, resetting your application password through email doesn’t always work correctly, especially if you haven’t tied your Mi Account, and in such cases, the only way out is to delete the secure apps and re-install them, which leads to loss of data inside them.

• 🔄 Check for system updates
• 🔋 Turn off energy savings for system services
• 🔐 Link your Mi Account to restore access

Timely firmware updates help to fix bugs associated with the operation of security modules. Xiaomi engineers regularly release patches that improve the stability of application protection.

💡

Regular system updates and Mi Account binding are the main ways to avoid problems with restoring access to protected data.

Additional Digital Hygiene Measures

Passwording apps is just one step in building comprehensive security, and to protect your data as effectively as possible, it is recommended to combine different methods, for example, using two-factor authentication in messengers and banking applications will add another level of complexity for attackers.

Also, don’t neglect the Guest feature if you give your phone to your kids or colleagues frequently, which allows you to use a device with a limited set of features and applications without affecting your personal data, and the combination of guest mode and application protection creates a robust access structure.

Regularly checking installed apps for suspicious permissions will help keep privacy, keeping an eye on what rights new programs request, and not giving access to contacts or a microphone unless urgently needed.
