How to password folder on the phone Android Xiaomi

In today’s world, smartphones store vast amounts of sensitive information, from personal photos to document scans and financial statements. Data security is especially acute for owners of Xiaomi, Redmi and POCO devices, as the MIUI shell and the new HyperOS offer unique but not always obvious protection tools. Standard screen lock protects only from physical access to menus, but does not hide the contents of files from prying eyes if the phone is unlocked.

Many users mistakenly believe that to protect folders, you need to download third-party programs from Google Play, which often contain ads or collect data. In fact, Xiaomi’s Android system already has a powerful encryption and file hiding mechanism built in, which works at the file system level. In this article, we will discuss native methods to create a reliable barrier to your data without installing extra software.

There are several layers of protection, from simply hiding application icons to fully encrypting the contents of folders in the repository. The choice of the specific method depends on how critical the data is and which use case you are closer to, and then we will look in detail at the algorithm of actions to create a secure space.

Use of the “Hidden Space” function in the Explorer

The easiest and most effective way to password a folder to Xiaomi Android is to use the built-in Hidden Space feature, which is available in the standard Explorer app, which is preinstalled on all devices of the brand, and the mechanism is based on moving files to an encrypted partition, access to which is only possible after entering a special password or a graphical key.

To activate the function, you need to open the Explorer application and go to the Folders tab. At the bottom of the screen, next to the Favorite button, there is often a folder icon or menu button, which opens the hidden folder creation menu with prolonged press or swipe. The system will suggest setting a password that may differ from the screen unlock password, which increases the level of security.

Once you create a hidden space, you can move files into it in two ways: the first option is through the Move to Hidden Folder menu in the file properties; the second, faster way is to pinch the file with your finger and swipe down the screen, after which the corresponding notification will appear.

⚠️ Note: When you reset your phone to factory settings or delete your Mi Account without first removing files from hidden space, the data will be lost irrevocably, as the encryption keys are tied to the current system configuration.

Setup to block applications for access to files

An alternative method, often used in conjunction with the previous one, is to block access to the conductor applications themselves or the gallery. The MIUI/HyperOS security settings have a separate Application Lock section, and by activating it, you can set a password to run any installed software, including standard Explorer, Gallery or third-party file managers.

This method does not encrypt files physically, but creates an effective barrier to them. If an attacker gets an unlocked phone, he will not be able to open the application to view files without additional code. To set up, go to Settings → Applications → Lock applications and activate the switchboard in front of the desired programs.

The feature of the implementation in Xiaomi is the ability to use a fingerprint or face unlock for quick access to secure applications, which makes the process of use convenient in everyday life, without requiring each time to enter a complex password, but maintaining a high level of protection from accidental access.

• 🔒 Lock works even in sleep screen mode, requiring authentication every time the application is launched.
• 👁️ Ability to hide notification content from blocked applications on the lock screen.
• ⏱️ Set the lock timer: immediately, 1 minute or 10 minutes after the release.

💡

Use different passwords to lock the screen and lock apps. If someone recognizes your pin code from your phone, they won't be able to access hidden files inside apps right away.

Creating a second space of complete isolation

Second Space is the most radical and reliable way to isolate data, and in fact, it creates a second, fully independent operating system on your phone with its own apps, accounts, photos, and files, and switching between the main and second spaces is instantaneous, often just by fingerprint or special code.

This solution is ideal for separating work and personal, or storing sensitive information, so you can move copies of apps (like a separate WhatsApp or bank customers) into the second space and fill them with specific content, so that the phone will look normal until you switch to a hidden profile.

You can find this feature by Setting → Second Space. When you first start up, the system will suggest setting up a separate password or fingerprint to log in, which creates a situation where one finger opens a regular phone and the other one opens a secret phone. All the data in these spaces are isolated from each other at the file system level.

💡

The second space is actually two different phones in the same case, making it the perfect tool for maximum privacy, but it requires more memory resources.

Working with protected notes and dictaphone

In addition to multimedia and documents, users often need to protect textual information. Standard Notes and Recorder applications in the MIUI shell have a built-in function to protect individual records, which allows you to store passwords, personal thoughts or important reminders in a common list, but only open them after authorization.

To pass a particular note, open it, click on the three dots in the top corner, and select Protect. After that, you need to verify your identity to view the content, and a similar mechanism works with audio recordings, which is true for dictaphone recordings of meetings or lectures that should not be accessible to outsiders.

It's important to understand that the protection only applies to the content within the application, and if you export a note to a text file or send it to a messenger, it will lose protection and become plain text, so use secure communication channels to transmit this data or archive password files before sending it.

⚠️ Note: Note protection only works inside the native app.If you delete the Notes app or clear its data, secure records may be lost if you don't back up through Mi Cloud with sync enabled.

Use of third-party file managers and encryption

If built-in tools are not enough, the market offers a lot of applications to create secure containers. However, when choosing third-party software, you should prefer open source solutions or time-tested programs such as Vault or File Hide Pro. Such applications create a virtual drive that looks like one large file, but inside stores your folder structure.

Third-party solutions often have the advantage of creating fake passwords, and when you type in code, the app shows a set of innocuous files, hiding real data, a social engineering technique that can save the day when you force them to unlock their phone.

When using third-party encryption, it is important to regularly back up containers to your computer or cloud. In the event of an app crash or Android update, access to proprietary encryption formats may be lost. Always check that the selected application is compatible with your version of Android.
