With a modern smartphone storing a huge amount of sensitive information, from personal photos to document scans, privacy becomes critical for every device owner. A hidden folder on Xiaomi is not just a convenient feature, but a necessary tool to protect your digital space from prying eyes. Owners of devices based on the MIUI shell often look for ways to restrict access to certain files without installing third-party and dubious applications from unverified sources.
Xiaomi has built-in encryption and data hiding mechanisms that work at the system level, providing a high level of security. You do not need to be a cybersecurity expert to set up private access to a gallery or file manager. In this article, we will discuss in detail all the available methods to securely hide your data.
Consider both standard system tools and additional features that will help you create a truly secure storage, and understanding Second Space and the hidden album will allow you to correctly distribute files and forget about the concern for their safety.
Use of the built-in Hidden Album in the Gallery
The easiest and most popular way to hide photos and videos is to use the native Hidden Album feature built directly into the Gallery app, which requires no additional software installation and works even without an Internet connection, making it ideal for fast media protection. The algorithm is extremely simple, but has its own nuances depending on the version of the MIUI firmware.
To activate the function, you need to open the Gallery app and go to the Album tab. Then you need to pull the list of albums down until the characteristic animation of the lock or stars appears. After that, the system will prompt you to set a password or use biometric data to log into the hidden storage. The password from the hidden album may differ from the password unlocking the screen, which provides an additional level of security.
⚠️ Warning: When you reset your phone to factory settings without first linking your Mi Account, access to the hidden album may be permanently lost. Always sync your key data to the cloud.
Once you set the password, you can move any images and videos to a hidden folder, and you can select the files you want, click the menu (three dots), and select the Hide option, which will visually disappear from the shared feed and only be accessed after you enter the access code through the swipe procedure described above.
☑️ Setup of a Hidden Album
Hiding applications through System Settings
The app hide feature allows you to remove program icons from your desktop and menu, making them available only through a special password or fingerprint. This is especially true for banking applications, messengers or games that you do not want to show to others. Unlike a hidden album, it hides the very shortcut to launch the program.
To activate this mode, go to Settings → Applications → Hidden Applications. In the list that opens, you will see all the programs installed on the device. Simply switch the switchboard opposite the desired application, and its icon will disappear from desktops. To run the hidden application, you will need to enter a special code in the Security application or use a configured biometric method.
There are several ways to invoke a hidden app if its icon is not on the screen. PIN-Security or use of a calculator widget with a secret code, if such a function is supported by your version MIUI. You can also set up a fingerprint launch, which greatly speeds up access.
- 🔒 Hiding apps doesn’t remove them, but only hides launch labels from outsiders.
- 👆 Access to hidden programs can be protected with a separate privacy password.
- 📱 The function works even in the “Guest” mode if it is configured accordingly.
It's important to understand that hiding applications is primarily a defense against prying eyes, not professional hackers, and that it's better to use additional encryption or Second Space to store critical data.
The Second Space (Second Space)
The most advanced method of data isolation is Second Space, which creates a virtual second operating system on your smartphone with separate desktops, apps and files, switching between the main and second spaces is instantaneous and requires a password or fingerprint.
To set up, go to Settings → Second Space → Create Second Space. The system will suggest setting up a separate profile by selecting the switching method (password or fingerprint). Once created, you will get a clean desktop where you can install separate copies of social networks, banking applications and store sensitive files. The data in the two spaces are completely isolated from each other.
Using Second Space is ideal for separating work and personal life, or creating a clean profile for kids. You can transfer files between spaces, but by default they're not visible in another profile. It's a powerful tool that turns one physical smartphone into two logical devices.
⚠️ Warning: Deleting the Second Space will result in the complete loss of all the data stored inside it.Be sure to back up important files before deleting it.

Working with hidden folders in the Explorer
The MIUI file manager also has an inbuilt folder hiding feature that works on an encryption principle, and the hidden folders in the explorer are invisible to other file managers and applications unless you log in to a dedicated partition, which is a great way to hide documents, archives and other types of files that are not media.
To create such a folder, open Explorer, go to the folder tab, and find the Hidden Folders section (usually requiring privacy password confirmation), you can move any files from internal memory there, the mechanism of operation is similar to a hidden album: files are physically moved to an encrypted memory area.
To access hidden files in the Explorer, you need to log in. After that, you can copy, move and open documents. It is important to note that when you clear the cache or delete the Explorer application (if possible in your version of the system without reset), the data may become unavailable, so regular backup remains relevant.
💡
Use different passwords for Hidden Album and Second Space, and if an attacker learns one password, the rest of your data will remain secure.
Comparison of data protection methods on Xiaomi
The right method depends on the type of data you want to protect and the level of paranoia you're experiencing, and each of the methods you're looking at has its advantages and limitations. Below is a comparison table that will help you determine the best solution for your situation.
| Method | Type of data | Level of protection | Accessibility |
|---|---|---|---|
| Hidden album | Photos, Videos | Medium. | Tall (swipe) |
| Hiding applications | Programme labels | Low/Mediocre | Medium (code/biometry) |
| Second space | All types of data | High-pitched | Medium (profile switching) |
| Hidden folders | Documents, Archives | Medium. | Tall (through conductor) |
As you can see from the table, Second Space offers the most comprehensive protection, isolating the whole environment, but it's more convenient to use a standard Hidden Album to quickly hide a pair of photos, and combining these techniques allows you to create a multi-layered security system.
Remember, software protection is only effective when you have a strong password, simple combinations like 1234 or 0000 won't protect your data from even basic matching methods, and use complex alphanumeric passwords and update them regularly.
💡
A combination of techniques (e.g. App Hiding + Second Space) gives the maximum privacy guarantee, but requires getting used to new smartphone use scenarios.
