How to Password Xiaomi Apps: Data Protection

Xiaomi, Redmi and POCO smartphones store a huge amount of sensitive information, access to which often does not require even unlocking the screen. Banking apps, personal correspondence in messengers and a photo gallery remain open to anyone who will take your phone in their hands. Standard screen lock protects the device only from external access, but does not hide the content of running programs from prying eyes in the circle of family or colleagues.

Fortunately, MIUI and its successor HyperOS offer an integrated App Lock tool that allows you to install additional protection on selected programs, which requires no third-party software installation, is stable and deeply integrated into the security system, and in this article we will discuss in detail how to activate this protection, what biometric methods are available, and what to do if you forget the access code.

Implementing an extra layer of security is not paranoia, but a necessary measure in today's digital world. Even if you're confident in your surroundings, losing your phone or stealing your finances and personal data can put your finances and your personal data at risk. App Lock locks an app immediately after it's closed or after a predetermined period of time, requiring re-authorization. Let's look at the setup process Step-by-step.

Preparation of security system and creation of password

Before you start blocking specific programs, you need to configure the protection mechanism itself. In Xiaomi devices, this process is tied to creating a special privacy password that is different from the screen unlock code, this is done specifically so that even if you know the screen pin code, an outsider can not access the hidden data.

The process starts with going to the settings menu, you need to find the protection section and initiate the creation of a new access key, and the system will offer several options: a pattern lock, a digital pin code or a long alphanumeric password. The choice depends on your preferences, but the pattern lock is often considered more convenient for frequent use.

So remembering it is critical. If you link a Mi Account, recovery is possible, but it's better to write the code to a secure location right away.

• 🔒 Go to Settings and select the App item.
• 🔐 Find the option to Block Apps (or App Lock) in the list).
• 🗝️ Create and enter a strong password, confirming it by re-entering.
• 👤 Link your Mi Account to allow you to restore access in case of forgetting your password.

⚠️ Note: If you do not link your Mi Account when creating a password and forget it, the only way to reset is to completely reset your phone to the factory settings, which will lead to the loss of all data.

Once you've successfully created a password, the system will suggest setting up additional security settings, so you can add a fingerprint or a face scan for quick access, which greatly speeds up the process: instead of entering a pattern lock every time, just tap the sensor or look at the screen.

Choosing applications to lock and fine-tuning

Once you have a common password, you will see a list of all the programs you have installed, and the interface is divided into two tabs: "Blocked" and "Not blocked." By default, all the apps are in the second category, and you need to manually move those you want to restrict access to.

Usually, users primarily protect bank customers, messengers like WhatsApp and Telegram, and a gallery, but the functionality allows you to hide other programs, such as a calculator with a secret file storage or system settings.

Special attention should be paid to the lock timer settings. In the upper right corner of the application lock screen, there is a gear icon. You can choose when to request a password: immediately after you log out, in a minute or only when you unlock the device, the optimal option is "Immediately" or "In 1 minute" so that if you accidentally fold the application, access to it is closed.

You can also activate the notification content concealment in the settings, so if this feature is enabled, even if a new message is sent to the blocked messenger, the notification text will not appear on the lock screen, which prevents information from leaking without the need to unlock the phone.

Using biometrics for quick access

Constantly entering a pattern lock can be annoying, especially if you need to quickly open the app several times a minute.Modern Xiaomi and Redmi smartphones are equipped with reliable biometric protection modules that can be integrated with the App Lock function. This makes the process of logging into secure applications almost invisible.

To set up, you need to have at least one fingerprint or face added to the system, and you need to find the corresponding item in the application lock menu and activate the use of biometrics, and then when you try to open a secure program, the phone will suggest that you attach a finger instead of entering a password.

It's worth noting that biometrics don't always work. Once the device is rebooted, or if it's been a long time since the last screen was unlocked, the system still requires you to enter the primary pattern lock. It's a standard Android security measure that you can't bypass software, and the fingerprint scanner must be functional and properly configured.

Using Face ID on Xiaomi works via a front-facing camera. While convenient, it is considered less secure than a fingerprint, since the owner's photo can theoretically unlock the device.

Hidden applications: privacy level higher

There's a feature in MIUI's security arsenal that goes beyond just locking, which is hiding app icons, and when an app is hidden, its icon disappears from the desktop and from the menu of all programs, and you can only find it through a special hidden app menu or through a search.

To activate this mode, you need to go to the theme settings or use a special gesture in the application menu (swipe two fingers to the sides) if it is enabled. Inside this space, you can add applications that are already password protected. This achieves double protection: you need to find the application first, and then unlock it.

Hidden apps don't show notifications on the lock screen and in the notification curtain unless otherwise specified. This is the perfect way to hide the presence of certain programs on the device, for example, if the phone can be used by children. However, remember that an experienced user can find hidden files through the explorer or settings.

• 🙈 Hide the app icon from your desktop for complete privacy.
• 🔍 Access to hidden applications is done through search or special gesture.
• 🛡️ Double protection: App Lock password plus hiding the fact of the program.
• 🔕 Notifications from hidden apps don’t appear in status curtain.

⚠️ Warning: When you reset your phone to factory settings, all hidden apps and files will be permanently deleted. Always back up important data.

Solution: Forgotten password and work errors

Despite the convenience, users sometimes face the problem of a forgotten password. As mentioned earlier, the Mi Account binding is a lifeline in this situation. If you forget the key, the password entry button will appear on the password entry screen, "Forgot your password?" By clicking on it and entering your account information, you can reset the protection and install a new code.

If the account was not tied, the situation is complicated: in older versions of MIUI there were vulnerabilities or ways to reset through safe mode, but in modern firmware HyperOS and current MIUI 14/15 protection is strengthened. The only official way is a complete reset of the device (Wipe Data), which deletes all user information.

Also, users may find that the app is not blocked or blocked too often. Check the timer settings in the App Lock menu. You may have selected the "When unlocking the device" mode, and the app only closes when the screen goes out. Change the setting to "Immediately" for strict control.

💡

Use Second Space to create a completely isolated environment with a separate set of apps and your own password, if standard locking isn’t enough.

Another common problem is that fingerprint unlocking doesn’t work for certain applications, which may be due to app limitations or security errors, such as cleaning the Security cache or updating the system to the latest version.

Differences in MIUI and HyperOS

With the release of the new HyperOS operating system, which is gradually replacing MIUI in the global market, the location of some elements may have changed. App Lock remained essentially the same, but the path to it became more logical. In HyperOS, security settings are often placed in a separate large menu "Security and privacy".

The visual style of the password windows has also been updated to be more minimalistic and more consistent with the new design of the system. Animations have become smoother, and the speed of fingerprint recognition to unlock applications has increased due to optimization of the kernel of the system. The functionality remains identical: you can hide applications and configure timers.

If you switched from the old Xiaomi to the new one with HyperOS, you wouldn't notice a big difference in usage. The interface has become cleaner, there's been no extra advertising in system applications (depending on the region), which makes the password-entry process less annoying. The biometrics algorithms have also been improved.

💡

Hyper-optimization: HyperOS processes biometric authorization requests faster than MIUI, making application login almost instantaneous.

For owners of mid-range and low-end devices (Redmi Note, POCO M), the transition to HyperOS can bring a noticeable improvement in the speed of the lock function, as the new system more easily consumes the resources of the processor.
