Xiaomi smartphone owners often face the need to hide personal photos or videos from prying eyes. The Redmi 8 Pro, despite its age, remains popular due to its balancing between price and functionality, including advanced MIUI shell capabilities. However, standard gallery access is open by default to anyone who unlocks the device's screen.
Protecting multimedia content is not just a fad, it’s an important part of digital hygiene. In this article, we’ll take a look at how to activate the built-in protection mechanisms that the manufacturer offers, learn about creating a Hidden Album, setting up biometric protections, and using additional applications to encrypt data.
The password process doesn't require superuser rights or complex software installations. All the necessary tools are already built into Android's MIUI shell. We'll look at each step in as much detail as possible so that even an inexperienced user can secure their data in a few minutes.
Built-in MIUI protection features on Redmi 8 Pro
The MIUI shell, which is installed on Xiaomi, Redmi and POCO smartphones, has a unique set of security features that differ from pure Android. One of the key features is the ability to create hidden file spaces. On the Redmi 8 Pro model, this feature works stably and allows you to hide not only photos, but also videos, notes and even entire applications.
System protection is based on a separate access profile that is not displayed in the standard gallery interface without authorization. A hidden album is not just a folder with a changed name, but an encrypted partition of memory, which requires confirmation through a pattern lock, a digital code or biometric data, if configured.
⚠️ Note: When resetting your smartphone settings to factory settings without first logging out of your Mi Account or saving your password from a hidden album, access to encrypted files will be lost forever.
It's important to understand the difference between simple deletion and real encryption, because when you hide a photo in a standard gallery, it just moves to a system directory that's accessible through the file manager, provided you have root rights, and using the native MIUI tool ensures that without a password, files are unreadable.
Preparing the device for security settings
Before you start setting passwords to the gallery, you need to make sure that the basic security settings of the smartphone itself are correctly executed.Without the main lock screen installed, the album protection function may not work correctly or be available. On Redmi 8 Pro, this requirement is mandatory.
Check the operating system version first. Although the interface may vary slightly depending on the MIUI update (versions 11, 12 or more), the logic remains the same.
☑️ Redmi 8 Pro Preparation for Protection
You can also choose the type of password you want to use, you can use the same pattern lock you used to unlock the screen, or you can create a unique code for the album only, and using the same passwords makes it easier to remember, but it reduces the overall level of security if one of them is compromised.
Make sure that the device is enabled fingerprint sensor located on the back of the Redmi 8 Pro. This will allow in the future to open hidden photos with one touch, which is much more convenient than entering combinations each time. → Passwords and security → Fingerprints.
Step-by-step: activation of the hidden album
The process of activating gallery protection on Xiaomi is hidden in the file management menu, not in the Photos app itself. This is done to hide the fact that the protected feature is available from the casual user. First, open the standard Explorer (or Files) application, which has a folder icon.
In the file menu that opens, swipe down from top to bottom. On some versions of MIUI, you swipe right to left or click three dots in the corner and select the appropriate item. You will be asked to set a privacy password. The system will prompt you to enter a pattern lock or a digital code.
Once you have entered your password, the system will offer to link your Mi Account, a critical step for Redmi 8 Pro, as it will be possible to restore access to photos through the account if you forget your password or change your device.
⚠️ Note: Privacy password is different from screen unlock password. Remember it or securely save it, as it is the only key to your hidden data.
Once you successfully set the password, the hidden album interface will open, and you'll see an empty gallery here. To add a photo here, go to the regular gallery, select the images you want, click the "More" button (three dots) and select Hide. Files will disappear from public access and only appear after you log in to the hidden partition.
💡
Use different patterns for the lock screen and the hidden album, which will create an additional layer of protection: even if you know the unlock code of the phone, an attacker will not be able to enter the hidden partition.
Biometric Access and Face ID
Entering a password can be tedious every time, so Xiaomi suggests using biometrics. On the Redmi 8 Pro, the fingerprint scanner works quickly and reliably. To activate this feature, go to the hidden album settings via the Explorer menu, swiping down to log in.
In the privacy settings menu, find Use fingerprint or face unlock. Activate the switches you want. The system will ask you to put your finger on the scanner several times for confirmation.
It is worth noting that biometric data is stored in a secure module of the Redmi 8 Pro processor and is not transmitted to servers. However, unlike a password, a fingerprint cannot be “changed” if it is compromised (for example, if there are quality prints on the glass), so a backup password remains mandatory.
| Protection method | Level of security | Convenience | Risks. |
|---|---|---|---|
| pattern lock | High-pitched | Average. | Screenprints, peeking. |
| Fingerprint. | Medium/High | Very high. | You can’t change it, there are possible false positives. |
| Digital PIN | High-pitched | Low. | It is difficult to remember long code. |
| Facial recognition | Low/Mediocre | High. | Can be unlocked by the owner's photo |
Alternative methods: third-party storage applications
If you don't have enough built-in MIUI features, or if you want to make it look like you don't have important data, you can use third-party apps. Google Play stores offer dozens of solutions, such as Calculator Vault or Gallery Vault, which are disguised as conventional utilities (calculator, voice recorder).
The principle of their work is to create an isolated container inside the memory of the phone. When you run a mask application (for example, a calculator) and enter special code, a hidden gallery opens. For Android on Redmi 8 Pro, this looks like the work of a regular application, and the files inside are securely encrypted by AES algorithms.
- 🔒 Calculator Vault – a popular application that hides a photo behind the interface of the calculator.
- 📁 KeepSafe – cloud storage with additional pin code protection.
- 🎭 Hide My App – allows you to hide the icons of any application, including the gallery itself.
The use of third-party software has its risks: developers of such applications can have access to the metadata of your files if cloud synchronization is used. In addition, if you delete such an application without first transferring files, they can be lost.
What happens to files when you delete a storage application?
Restoring access and solving problems
The most common problem that Redmi 8 Pro users face is the forgotten password from the hidden album. If you have attached Mi Account, the recovery will be successful. On the password screen, click the Forgot password button?. The system will redirect you to the Xiaomi account authorization page.
Once you have successfully logged in, you will be prompted to set a new privacy password, and the old files will remain in place, as they are linked to your account, not to a particular device. Unless the account was linked, unfortunately, it is technically impossible to restore access to the Hidden Album due to the use of encryption algorithms.
In some cases, users complain that hidden photos disappear after a system update. They are usually not deleted, but simply hidden from view due to a failure in the media index. Try clearing the Gallery and Explorer app cache through the Settings → Apps → All apps menu.
⚠️ Warning: Never attempt to root the Redmi 8 Pro solely for the sake of accessing hidden files.This may compromise encryption integrity and result in complete data loss, and void warranty.
💡
The only guaranteed way to keep your hidden photos safe is to link your Mi Account when you set your password, and without that step, you can't restore access.
