How to Set a Password on a Xiaomi Folder: Data Protection

Xiaomi, Redmi and POCO smartphone owners often face the need to hide personal information from prying eyes. The MIUI shell and its modern HyperOS offer powerful built-in privacy protection tools that do not require additional software installation. The file hiding feature works at the system level, which ensures the safety of data even when trying to access through third-party file managers.

The procedure for installing protection can vary depending on the version of the operating system and regional firmware. In some cases, the standard menu can be hidden or changed by the manufacturer. The setting of a password for a specific folder in the classical sense (as an archive) is replaced here by moving files to a special secure container, access to which is possible only after entering a code, a pattern lock or a fingerprint.

This article looks at all the ways you can restrict access to your data, and we’ll look at the system’s regular tools, the features of working with a hidden folder, and alternative methods through third-party encryption applications, and understanding these mechanisms will allow you to create a reliable barrier to curious views.

Standard protection in MIUI and HyperOS

Xiaomi’s security system is built around a single security management center, and this is where the main controls for accessing content are located. Unlike many other vendors, Xiaomi has integrated file hiding directly into the system layer, making it more reliable than simple calculator apps with a stash.

To activate the protection, you first need to create a Privacy Password, which is a unique code that is different from the screen unlock password and can include a digital pin code, a pattern lock or biometric data, without installing this primary barrier, further settings will not be available.

⚠️ Note: Privacy password cannot be restored through your Mi Account unless you have previously linked it to your security settings.Forgotten unassociated code leads to complete loss of access to hidden files.

Once you create a password, the system will prompt you to set up questions to restore or link to Mi Account. You should not ignore this step, since resetting the device will not help restore access to the encrypted container. Data encryption occurs automatically when you move files to a secure area.

Creating and Configuring a Hidden Folder

The main tool for protecting data is called the Hidden Folder, which is not just a folder with a password, but an isolated space in the memory of the device, and the files that are placed there disappear from the gallery, the music player and the standard file manager.

To find this tool, open the Explorer (Files) app. At the top of the interface, there is often a tab or button with the corresponding name. If it is not there, try swiping your finger down the file list — in many versions of MIUI, this action opens the entrance to the hidden storage.

The first time you log in, you'll need to enter a previously created privacy password, and after you've successfully logged in, you'll have a hidden storage interface, you can create new folders or move existing ones, and it takes seconds to move files, and you don't need to copy the data, you just change the path to it in the file system.

Step-by-step instructions: how to hide files

The process of transferring data to a secure zone is as simple as possible for the user: you can work with individual files or entire directories. The algorithm of actions is the same for most versions of the firmware, but the visual design of the menu may vary slightly.

Follow the instructions to securely close access to selected documents:

  • 📂 Open the standard Explorer app and find the files you need to hide.
  • 🖱️ Press and hold your finger on a file or folder to highlight them (a tick will appear).
  • 🔍 In the bottom menu, select More (three dots) and find Hide.
  • 🔒 Confirm the action by entering a privacy password or scanning a fingerprint.

After these steps are done, the files will disappear from the current location, and you can only find them through the entrance to the Hidden folder using a password.

Where do files go when you reset your phone?
When you completely reset your smartphone to your factory settings (Wipe Data), the contents of the Hidden Folder are also deleted without recovery if you don’t have a backup done off-device. > Using third-party encryption apps If Xiaomi’s built-in tools don’t seem flexible enough, the market offers a lot of third-party solutions. Encrypted applications allow you to create secure containers that look like regular files or system processes. This adds an additional layer of secrecy. Popular applications like Calculator Vault or KeepSafe masquerade as computational utilities or cloud storage. Function Embedded folder Xiaomi Third-party applications Integration into the system High Low Masking icon No (visible in Explorer) Yes (calculator, audio) Account Dependence Linked to Mi Account Depends on developer Deletion Risk Minimum High when clearing cache Use Third-party software requires permissions, and applications can request access to all files on the device, which theoretically reduces the overall level of security, despite having a password for the folder itself. Data protection is meaningless if you can't use it yourself. MIUI There is a mechanism for restoring access through the Mi Account. To do this, when setting up the privacy password, you need to log in to the system. This allows you to reset the forgotten password through the web interface or when you reconfigure the device. However, if the account was not tied, the only way to return files is to remember the code. Biometrics (fingerprint or face) is only a handy key, but does not replace the main password in the case of a reset security settings. Regularly backing up important documents to an external medium or to the cloud (pre-shooting them out of a hidden folder) is the only guarantee against loss. ⚠️ Note: When you delete the "Security" or "Conductor" application (if these are system components) through ADB, Access to Hidden Folder can be lost forever.Do not delete Xiaomi system components.Frequently asked questions (FAQ) Can you hide entire apps on Xiaomi? Yes, it uses the Hide Apps feature, which is in the settings (Settings) → Annexes → Hiding applications). It works separately from the Hidden Folder, and requires you to enter a password or use a second space to run hidden programs. Are hidden files visible when you connect your phone to your computer over USB? No, when you connect in file transfer mode (MTP), the hidden folders do not appear in the computer conductor. They are only available inside the phone operating system after authorization. What happens if I forget the password from the Hidden Folder? If you tied the Mi Account, you can try to reset the password through it. Otherwise, the data will be lost. Xiaomi encryption system does not "bypass the computer's computer's memory. They are only hidden from the user's internal memory, and they take their place in the stored files in the storage? You can only free up space by removing files from a hidden container.
