Xiaomi and Redmi’s modern smartphones hold a wealth of personal information, including intimate photos and sensitive documents. The standard gallery often gives access to these files to anyone who has simply unlocked the device’s screen, making privacy a critical issue for millions of users around the world.
MIUI (and its new version of HyperOS) has built-in security tools that can securely hide and encrypt media files without installing third-party software. You can create a hidden album that is protected by a separate password, pattern lock or biometrics, the first and most important step to ensuring the digital security of your personal data.
In this article, we will go into detail all the ways to password a photo on Android from Xiaomi. We will look at the standard features of the system, the nuances of the hidden album, as well as advanced methods like creating a second space. Understanding these mechanisms will allow you to feel confident, handing the phone to children or colleagues.
State Hidden Album in the Gallery App
The easiest and fastest way to restrict access to images is to use the built-in Hidden Album feature, which is integrated directly into the standard Gallery app and does not require additional system settings, and when activated, selected photos disappear from the general stream and become visible only after entering a password.
To activate, you need to open the Gallery app and go to the Albums tab. At the top of the screen, you need to pull the album list down until the lock animation appears. The system will suggest creating a privacy password that will differ from the screen unlock password, and once you set the access key, you can move any images there.
It's important to understand that the files in the hidden album are not just hidden, they're encrypted, even when you connect your smartphone to your computer through a computer. USB-In the file transfer mode, this data will remain inaccessible without unlocking the device itself and entering special code.
💡
The hidden album encrypts files locally, making them invisible even when connecting a smartphone to a PC in data mode.
⚠️ WARNING: If you forget the password from the hidden album and don't link a Mi Account to recover, it's almost impossible to get back access to photos. Xiaomi's security system doesn't store your passwords on its servers in plain sight.
Set up passwords and biometrics for access
Quality protection requires the right authentication techniques to be configured. In MIUI's privacy settings, you can choose which method to use to open hidden albums, which can be a digital code, a pattern lock, a fingerprint or facial recognition.
Using biometrics makes access much faster, but it has its nuances: for example, facial unlocking is less reliable in the dark or if you're wearing a mask, whereas the fingerprint scanner in modern Xiaomi models works steadily. Digital or graphical password remains the most reliable, although it takes longer to type.
To set up, go to Settings → Passwords & Security → Privacy. You can change your existing password or add biometrics. It is recommended to change the access code periodically, especially if you suspect that someone may have seen you enter it.
- 🔒 The pattern lock is convenient for quick input, but can leave traces of fat on the screen that are easy to count.
- 🔢 A digital password of 6 or more characters is considered the most resistant to selection, but it is more difficult to remember.
- 👆 Fingerprint provides a balance between speed and security, being the standard for today’s smartphones.
- 👁️ Facial recognition is comfortable, but inferior in reliability to other methods in bright light or similar to the owner.
Use of the Second Space function (Second Space)
For those who want maximum data isolation, Xiaomi offers Second Space, which creates a completely separate environment inside the smartphone with its apps, accounts and gallery, in fact, you get two in one: a regular phone and a hidden phone inside it.
The second space is accessed through a separate fingerprint or a special password, and if you are asked to unlock your phone, you can use a "normal" finger, and the attacker will only see your standard photos. Using a "hidden" finger will instantly switch the system to the Second Space mode, where secret files are stored.
This feature is ideal for separating work and personal content, or for parents who want to restrict their children’s access to certain files, but it is worth considering that having two spaces takes up more space in the device’s memory and can slightly increase battery consumption.

Comparison of Media File Protection Methods
The choice of protection method depends on your specific needs and level of paranoia. The hidden album is good for quickly masking several shots, whereas the Second Space is suitable for storing entire archives of confidential information.
| Characteristics | Hidden album | Second space | Third-party annexes |
|---|---|---|---|
| Level of protection | Medium (file encryption) | High (system isolation) | Depends on the developer. |
| Speed of access | Quick (one password) | Medium (profile switching) | Slow (launch of the application) |
| Impact on the battery | Minimum | Medium (background processes) | High (advertising, services) |
| Difficulty setting up | Low. | Medium | Low. |
Third-party storage apps often require additional permissions and may contain ads, making them less preferred than Xiaomi's built-in solutions.The built-in tools are optimized for hardware and do not conflict with the system, ensuring stable operation.
Working with files through a conductor
Not only can you hide photos from the gallery, but you can hide any other files using System Explorer, and the way it works is the same: files move to a secure folder that requires authorization. PDF-Documents, video files or archives.
To hide a file through Explorer, find it in the list, press and hold your finger to highlight. In the menu that appears, select Hide. The file will be moved to the system storage. You will not be able to find it in the usual way through the file system without root rights.
To return the file back to the public, you need to go to the hidden file settings through the Explorer or Gallery menu, enter the password and select the option "Delete from hidden". After this procedure, the file will again appear in the public domain and will be visible to all applications.
☑️ Checklist of security of your photos
Access Restoration and Backup
Despite all the precautions, the human factor has not been reversed, and a forgotten password can be a serious problem, which is why it is critical to link your Mi Account to a privacy protection feature, which is the only legal way to reset your password without losing data.
When you set up a hidden album, the system urges you to link your account. Don't ignore this step. If you lose access to your password, the key entry screen will show a link "Forgot your password?". By clicking on it and logging in to your account, you can set a new access code.
It is also recommended to regularly back up important photos to the cloud (such as Google Photos or Xiaomi Cloud), but be careful about syncing hidden albums. Often such albums are not synced by default, which is a plus for security, but a minus for data security when your phone breaks.
⚠️ Warning: Resetting your smartphone to factory settings (Hard Reset) without first untiing your Mi Account and privacy password can lead to a complete lock of the device with the Anti-Theft function.
