Xiaomi’s Redmi 9 series of smartphones remain popular thanks to their value for money and the functionality of the MIUI shell. In today’s digital world, protecting personal information is becoming the number one priority for every user.
Many people store confidential emails, photos, or banking apps on their phones that are not desirable for outsiders to access, and standard screen locking is often not effective enough if you give a device to a child or colleague for a quick call.
Fortunately, Android with the MIUI add-on has a powerful built-in feature that allows you to set an individual password to run specific programs, which does not require installing third-party software and is performed in a few minutes directly in the system settings.
The Benefits of Integrated Protection in MIUI
The use of native shell tools Xiaomi gives a number of undeniable advantages over third-party solutions from Google Play. First, system protection works at a deeper level, which makes it almost impossible to bypass without resetting settings.
Second, integration with biometrics allows you to use Face ID or fingerprint for quick access, which is much more convenient than entering a digital code each time.
It’s worth noting that the feature works even in the background, blocking notifications from secure apps until the device is unlocked.
This ensures that the contents of messages from WhatsApp or Telegram will not be visible on the blocking screen to unauthorized persons.

Use a complex graphical key for applications other than the screen unlock key to increase security.
Preparation for the installation of protection
Before you start setting up, make sure your Redmi 9 is up to date, and while the feature is present in most versions of MIUI, older builds may contain vulnerabilities.
It is also important that the device has a lock screen password (PIN-Without this basic security level, the system will not allow the creation of a separate access profile for programs.
If you haven’t used security features before, it will take time for the system to create a secure key store.
Make sure the battery is at least 20-30% so that the device does not turn off at a critical time of setting the security settings.

☑️ Checking security settings
Configuring biometric access
Entering a password every time can be tedious, especially if you use secure apps often.Redmi 9 features a fingerprint scanner on the back and a face unlock module.
To activate a quick sign-in, go to the Application Protection menu and click on the gear icon in the upper right corner. In the menu that opens, find Unlock and select a convenient method.
It is recommended to use a fingerprint, as this is the most reliable and quick way. facial recognition on budget models can work slower and less accurately in poor lighting.
You can also configure the content of notifications to hide the text of messages not appear in the curtain without unlocking.
💡
Biometrics makes access much faster, but remember that a fingerprint cannot be changed, unlike a password.
The function of Hidden Space
For users who want to maximize privacy, MIUI has a Hidden Space mode, a separate, isolated environment where apps, photos and files can be moved.
Unlike simple locking, applications in hidden space disappear completely from the general list of programs and do not appear in the settings.
Access to this space is through a special guest mode or entering a secret code in the dialing field.
It’s ideal for storing extremely sense-driven information that even those with access to the phone’s main interface shouldn’t see.
⚠️ Note: When you reset your phone to factory, the Hidden Space state will also be completely removed without the possibility of recovery.
Table of comparison of protection methods
To better understand the differences between the available security options on Redmi 9, let’s look at their main features in a comparative table.
This will help you choose the best use case based on your data protection needs.
| Protection method | Level of secrecy | Speed of access | Difficulty bypassing |
|---|---|---|---|
| Application lockdown | Low (visible on the list) | High (with biometrics) | Medium |
| Hidden space | Maximum | Medium (entrance required) | Tall. |
| Guest mode. | High-pitched | Low (switching) | Tall. |
| Second space | Maximum | Medium | Very high. |
As can be seen from the table, the usual application blocking is suitable for everyday protection from curious glances, but does not hide the fact that the program is available.
For more serious tasks, it is better to combine methods or use a Second Space, which creates a second phone inside the same device.
Possible problems and solutions
Sometimes users are faced with a situation where the security function is not working correctly or stops asking for a password.
A common cause is a system security process malfunction or conflict with installed memory optimizers.
Try clearing the Security app cache through the App Management menu.
Also check if the program is on the power saving exception list, as aggressive battery optimization can unload the password verification process from memory.
