How to put a password on the folder Xiaomi: full instructions

With smartphones storing a huge amount of personal information, from working documents to intimate photos, data protection is becoming critical for every owner. Owners of Xiaomi devices running MIUI shell or the new HyperOS often face the need to hide certain files from prying eyes. Fortunately, the built-in functionality of the system allows you to implement reliable protection without installing third-party software that may contain vulnerabilities.

In this article, we will discuss how to put a password on a folder on Xiaomi using native security tools that are already integrated into your device. We will look at the Hidden Album function for media files and the capabilities of the built-in document guide, and also discuss the nuances of biometric protection. A competent privacy setting will take only a few minutes, but will ensure the peace of mind for the safety of your data in any situation.

Many users mistakenly believe that folder encryption requires complex applications from the store, but Xiaomi engineers have provided all the necessary mechanisms at the system level. Below we will describe the step-by-step process of activating the protection so that you can easily navigate the settings menu. Understanding these processes will allow you to effectively manage access to confidential information.

Preparing for data protection and setting up security

Before you start hiding folders directly, you need to make sure that the device has the right security settings. MIUI requires you to set the main password to unlock the screen or the pattern lock, as this is often the basis for encrypting protected areas. If you still use simple swipe opening or no protection, the system will require you to change these settings before activating hidden space.

It is also important to link your Mi Account, because it is possible to restore access to hidden files in the case of a forgotten password through it. Without a tied account, the risk of data loss when a system crash or attempt to reset is significantly increased, and it will be almost impossible to restore access.

⚠️ Warning: Forgotten password from a hidden album or folder without a Mi Account tied and pre-set control questions often leads to irretrievable data loss, since there are no workarounds in modern versions of Android.

It is also recommended to update the system applications “Security” and “Gallery” to the latest version through the built-in store GetApps. Developers regularly release patches that improve the operation of encryption mechanisms, and the use of outdated versions can lead to incorrect display of hidden files or errors when entering a password.

Make sure your device has a Find Device feature that allows you to remotely lock your smartphone or erase data in the event of a theft, which adds to local folder protection, creating a layered defense system for your personal information.

Use of the Hidden Album function in the Gallery

The most common security scenario is hiding photos and videos. Xiaomi's built-in gallery has a powerful tool called Hidden Album that encrypts media files and hides their previews from shared feed. To access this feature, you need to open the Gallery app, go to the Album tab, and pull the album list down until the characteristic animation of the lock appears.

When you first start, the system will prompt you to turn on the function and set a separate password or use a biometric (fingerprint). Once activated, you can move any photos and videos to this album directly from the gallery interface, selecting the appropriate item in the Add to menu. Files placed here disappear from public access and require authorization to view.

• 🔒 Hidden photos are not displayed in widgets on the desktop and are not visible when connecting the phone to the computer in file transfer mode.
• 📸 When shooting in the mode “Hidden album” photos are saved immediately in a protected space, bypassing the general gallery.
• 👁️ Hiding the album is possible not only with a password, but also by setting up the display of its icon in the list of albums.

It is important to note that deleting photos from hidden albon is an irreversible action if you do not use the basket inside the application itself.The data encryption in this section is automatic, making it impossible to read files even when you connect the phone’s memory to the reader.

💡

For quick access to the hidden album, you can add a widget to the desktop, but remember that this will make the fact of the presence of hidden files more obvious to others.

Protect folders through built-in Explorer

To work with documents, archives and other types of files, MIUI has its own file manager, which also supports folder hiding. To use it, open the Explorer app, go to Documents or Folders, select the desired directory and click Hide.

Access to hidden folders in the Explorer is done in a similar way to a gallery: via swipe down in the corresponding section or through entering a special password. This creates an additional level of privacy, because even if someone unlocks your phone, they will not be able to find important documents without knowing the second access code.

Keep in mind that when you move files to a hidden folder, they physically change their path in the file system. Links to files saved in other applications (for example, in text editors) may stop working, as the original path will become inaccessible without authorization.

Some users prefer to create password archives before placing them in a hidden folder, creating a double layer of protection, especially for financial documents or passport scans, which can have serious consequences.

Set up the Second Space for Total Insulation

If you don’t just want to hide a folder, but create a completely separate environment with other apps and accounts, Second Space is the perfect solution, creating a virtual clone of your smartphone that looks like a new device with a clean desktop and its own security settings.

Switching between the main and second spaces is instantaneous through a special shortcut in the notification curtain or fingerprint, and in this isolated space, you can set a separate password, your Google and Mi accounts, and hide the fact that the second space is there by setting a unique fingerprint to log in to.

Using Second Space is especially important for separating working and personal smartphone use, or for handing the device over to children without risking access to adult information, the most powerful privacy tool in Xiaomi’s arsenal.

Biometric protection and access management

Modern Xiaomi smartphones are equipped with advanced biometrics modules that can be effectively used to protect folders. In the security settings, you can set the entrance to a hidden album or a second space for fingerprint or facial recognition, which significantly speeds up access and eliminates the need to enter digital code every time.

But remember, biometrics is a convenience, not an absolute protection. Unlike a password, a fingerprint cannot be "changed" if its data is somehow compromised, although in practice, it is impossible to hack a finger scanner at a distance.

• 👆 Set up fingerprint login for instant access to hidden files without entering code.
• 👤 Use facial recognition only in combination with PIN-code.
• ⏱️ Set lock timeouts so that the device requests a biometric or password after a certain downtime.

You can also set up the Passwords and Security menu to set up Advanced Protection, which requires you to enter a password when you try to change your system settings or install applications from unknown sources, which will prevent the accidental or malicious installation of spyware that could access your hidden folders.

Restoration of access and common problems

Despite all the precautions, users sometimes forget passwords or experience technical glitches.If you forget the password from a hidden album but have attached Mi Account, the system will suggest restoring access through a password reset by sending the code to a linked number or email.

In cases where the account is unlinked and the password is lost, the data in the hidden album is considered lost forever for security reasons. No service centers or third-party programs will be able to recover the content, since the encryption keys are stored in a secure module of the processor.

⚠️ Warning: Resetting your phone to factory settings will result in the complete removal of hidden albums and files from the explorer, so before any radical action be sure to extract data from the security.

A common problem is that hidden files disappear after a system update, usually they just stop showing because of an indexing failure, in which case cleaning the Gallery or Explorer app cache through the application management menu helps, which does not delete the files themselves, but only updates the media database.

💡

The only guaranteed way to not lose access to hidden files is to regularly back up important data to an external medium or to cloud storage with two-factor authentication.

If you plan to sell your phone or redeem it, be sure to remove all hidden spaces and complete a full reset with internal memory formatting. Simply deleting files is not enough, as they can be restored with special utilities, whereas formatting makes recovery extremely difficult.
