Owning a modern smartphone involves storing a huge amount of personal information, among which photos often occupy a special place. Document shots, tickets, personal selfies or just funny shots do not always need to be available the first time you unlock the screen, especially if you often give the phone to friends or colleagues.
Fortunately, MIUI shell and its successor HyperOS provide a built-in and robust mechanism to protect sensitive files.You don't need to install third-party container apps that may contain ads or collect data.
The hidden album system function works at the file system level, making files invisible to the standard gallery and most third-party applications without authorization. In this article, we will discuss in detail how to activate this feature, configure access, and what nuances exist when working with secure media files in the Xiaomi ecosystem.
Activation and customization of the hidden album
The first step to protecting your data is to enable the feature correctly, which by default may be inactive or hidden from the user's eyes so as not to overload the interface with unnecessary elements.
At the top of the screen, you'll see tabs like "Photos," "Albums," and "Detect." You'll need to go to the Album tab, and that's where, scrolling down to the very end, you'll find "Hidden Album." If you click on it, the system will suggest you turn on this feature.
Once activated, you will be asked to give a password, which could be a pattern lock, a digital code, or a password other than the unlock password, and remember this code, because it can be extremely difficult to restore access without it.
☑️ Album security setting
It's worth noting that the latest versions of MIUI 14 and HyperOS may have slightly different interfaces, but the logic remains the same: the system will ask you to link the album to your Mi Account, which is a critical step: it will allow you to restore access to photos if you forget your password or change your device.
⚠️ Warning: If you don’t link your Mi Account when creating a hidden album, resetting your phone to factory settings will lead to the irretrievable loss of all hidden photos.
How to add and hide photos
Once the repository is built, the question is, how do you move files? There are several ways, each of which is convenient in certain situations, and the easiest way is to use the standard gallery interface.
Open any photo or video you want to hide. Click three dots in the corner of the screen or swipe up to open the action menu. From the options list, select Hide (or lock icon) and the file will disappear from public access instantly.
The second is for mass movement, so you go into an album, you highlight some photos with a long press, and then you press the button "Still in the bottom menu," and you also have a hidden option.
- 📸 Through the context menu: Select a photo → Menu (three dots) → Hide.
- 📂 Through highlighting: Long press → Choose a few → Hide the button".
- 📥 When saved: Some applications allow you to immediately save downloaded files to a hidden album, if this is allowed in the system settings.
It's important to understand that the process of hiding is actually moving a file to a secure directory. The original photo in the shared gallery is deleted. If you want to just copy the photo, do a duplicate first, and then hide one of the versions.
Technical details of the movement
Entry and access control to the album
Hidden material is accessed through the same input as activation, and in the Gallery app, you need to find the item "Hidden Album" in the tab of the Album.
When you click, the system will request authorization. Depending on the settings, it can be password input, fingerprint scanning or facial recognition. If you use biometrics, make sure that the phone's security settings allow the use of a fingerprint to access protected files.
There's an interesting caveat for those who want to hide the function as much as possible: In the settings of a hidden album, you can turn off the display of its icon in the album list, in which case, to enter, you will need to perform a special gesture: in the list of albums, pull a finger from the bottom up and hold for a few seconds.
| Access method | Description of action | Level of security |
|---|---|---|
| Password. | Entering numbers or a pattern lock | High-pitched |
| Print. | Putting your finger on the scanner | Medium (depending on the type of scanner) |
| Face ID | Facial recognition (on supported models) | Medium. |
| Swipe up. | Hidden gesture on album list | Low (Protection from casual gaze) |
Remember that if you change the unlock password, the password from the hidden album won't automatically change unless you've set the sync. This can lead to confusion, so it's better to use different but memorable combinations.
Working with Google Photos and Cloud Services
Many Xiaomi users are actively using Google Photos for backup, and this raises an important question: do hidden photos go to the cloud? By default, no. The hidden MIUI album is isolated from standard synchronization mechanisms.
If you need to back up your hidden photos, you’ll have to manually remove them from the album or use the sync function inside the hidden album itself if it’s available in your firmware version, but this can reduce privacy as the files appear in your Google cloud account.
In some cases, users want to transfer hidden photos to a computer, first make them visible (remove them from a hidden album), after which they will appear in a folder. DCIM or Pictures when connected to a PC USB. Direct access to the hidden folder through MTP-shutdown.
⚠️ Note: When you delete the Gallery app or reset the application settings, the hidden album data is not deleted, but access to it may be lost without being linked to the Mi Account.
And there's also the Mi Cloud feature, which is that if you enable the hidden album sync with the Mi Cloud, your photos will be password protected in the cloud, and even if you log in from another device, you won't see those photos without an additional password.
Restoring access and solving problems
Situations where a user forgets a password happen often. If you have linked a Mi Account, it will take a couple of minutes to recover; on the password screen, select the option "Forgot your password?"; the system will prompt you to send the confirmation code to the associated phone number or email.
Once you enter the code, you will be asked to set a new password, all files will remain in place. If the account was not tied, the situation becomes more complicated. In older versions of MIUI, there were vulnerabilities that allowed you to bypass ADB protection, but in current builds of HyperOS and MIUI 14, encryption has become much stricter.
The table below presents the problems and ways to solve them:
| Problem. | Possible cause | Decision |
|---|---|---|
| No print in. | Dirty finger or sensor failure | Use a password or reconfigure biometrics |
| The album is missing from the list. | Icon cover-up included | Swipe up the list of albums |
| Photos don't open. | File is corrupted or format is not supported | Try opening through the file manager after extraction |
| Forgot the password. | The human factor | Recovery through Mi-account |
💡
If you plan to sell a phone, be sure to extract all the photos from the hidden album and delete the album itself through security settings, rather than just reset the phone.
Alternative methods of gallery protection
Hidden albums aren’t the only way to protect yourself. Xiaomi has other tools that can be useful in the complex, such as Second Space, which creates a completely isolated environment in the phone with its apps and gallery.
Switching between the main and second spaces is done by fingerprint or password, which is ideal if you want to show someone a phone, but you don't want them to even guess the existence of hidden files.
You can also hide entire applications. Go to Settings → Apps → Hide apps. You can make the icon of the gallery or any other application disappear from the desktop, and you can only run them through a special window called by a gesture or through a search.
- 🛡️ Second Space: Complete data isolation, as if you had two phones.
- 🙈 Hiding apps: Icons disappear, but data remains accessible through settings.
- 🔒 Application Locking: Requires a password when you start a particular application (e.g., Gallery).
Using a combination of techniques (e.g., hiding the Gallery app + using a hidden album inside it) creates layered protection that is extremely difficult to get around without special knowledge.

Combining Hidden Album and Second Space ensures maximum data privacy on Xiaomi devices.
