Xiaomi’s MIUI system offers users a unique feature called Second Space, which allows them to create an isolated environment on a smartphone that works as a separate device with their apps, photos and settings. However, users often find themselves in a situation where they forget the password or pattern lock that blocks access to this hidden partition. Access recovery is not always smooth due to Android’s security policy.
Unlike the main screen, there are more stringent restrictions, as the second space is often used to store sensitive data. Trying to bypass security by standard methods can lead to loss of information. In this article, we will discuss in detail whether it is technically possible to find out the forgotten code, what legal ways to reset, and how to minimize the risk of losing important files when you restore access to the system.
It is worth noting that modern versions of Android and the MIUI shell use data encryption, which makes it impossible to directly “hack” or view passwords without special tools available only to security services. Therefore, the main focus of the guide is on methods of resetting and restoring access through tied accounts. Understanding the principles of encryption will help you choose the right strategy for dealing with a critical situation.
The principles of protection in MIUI
The second space function is designed to separate personal and work lives, and to hide certain applications from prying eyes. When you install security, the system creates a separate container of data that is encrypted independently of the main system, which means that even with full access to the main space files, you will not be able to read the contents of the second without the corresponding decryption key.
Security in Xiaomi is built on a multi-level system of checks. If you enter the wrong password several times, the system can temporarily block login attempts or require confirmation through Mi Account. This is done to protect against brute-force code selection. If there was an easy way to reset a password without losing data, it would create a huge security breach for all users.
⚠️ Warning: Attempts to use third-party programs to "hack" a second space often result in a device lock or all data being deleted without the possibility of recovery.
It's important to understand the difference between resetting the lock screen password and the second space password. In the first case, sometimes logging in through a Google or Samsung/Mi Account helps. In the second case, if you haven't set up sync or backup, data can be lost when you reset. Data encryption is a two-way process: it protects your files, but makes them inaccessible when you lose your key.
Can access be restored without data loss?
This is a question that most people find themselves in locked situations worry about, and unfortunately, the answer is 90 percent negative unless specific measures have been taken in advance. Current Android Security standards don't store passwords in plain form even in system files that are available to the user. So it's technically impossible to "learn" the old password, you can only reset it.
There's a single scenario where data can be saved. This works if you pre-assign the second space to the main space and set up a quick switch or backup function through Mi Cloud, so if you log in to the main profile, you can try to change the security settings through the second space management menu, but if you're locked in the second space completely, this method won't work.
- 🔒 Without a pre-created backup, data recovery after password reset is impossible.
- 📱 The main space link allows you to manage the second profile, but does not always give access to the forgotten code.
- ☁️ Sync with Mi Cloud can save contacts and photos, but not the settings of applications inside an isolated profile.
If you don't set up sync, when you reset your password, the system will have to delete the second space container along with all of its contents, which is not a bug, but a security feature, and the data is considered so secure that without the key it becomes digital garbage, so before any manipulation, you should try to remember the combination several times or check if it is recorded somewhere in the main profile notes.
💡
If you have access to the main space, check the Security -> Second Space app, and sometimes you can see a hint or change the unlock method if the system allows.
Reset via Mi Account and Find Device
One of the most effective ways to regain control of a device or its individual functions is to use Xiaomi’s Find Device cloud service, which requires that the device be enabled to access the Internet and sign in to Mi Account, and if the second space is created under the same account as the main one, the chances of success increase.
First, you need to go to the official website of the Xiaomi cloud service from a computer or other smartphone. By entering your credentials, you will get access to the control panel. Here you need to find your device in the list and choose the option to lock or clean. However, be careful: the “Erase” command often deletes all data on the device, including the second space.
| Action. | Influence on the main space | The impact of the second space | Data retention |
|---|---|---|---|
| Lockdown | Locks the screen. | Blocking the entrance. | Yes. |
| Sound signal | Turns on the sound. | Turns on the sound. | Yes. |
| Clearing the data | Total reset | Complete removal | No. |
| Change of password | Changes the entry code. | Maybe not touch it. | Depends on the MIUI version. |
Some versions of MIUI have the option to remotely change the screen unlock password, which can sync with the second space if they use a common authentication method. Try changing the main screen password through the web interface, and then entering a new code on the locked device. This can "rewrite" an old forgotten key.
What if the Find Device can’t see the device?
Using Recovery Mode to Reset Completely
When the soft methods don't work, the radical but effective way is to reset through Recovery Mode, which will give you back access to your phone, but completely remove the second space along with the data, and it's the only guaranteed way to unlock if the password is forgotten forever.
To enter recovery mode, turn off your smartphone. Then press the power button and the volume button at the same time. Hold them until the Mi logo or the Recovery menu appears. Depending on the firmware version (Global or China), the control can be done with volume and power buttons or be touch-sensitive.
☑️ Algorithm of actions in Recovery
Once you select Wipe Data -> Wipe All Data, the system will request confirmation. Once you complete the process, the phone will return to factory settings. When you first boot, the device will require you to enter the Mi Account password that was previously set, which is FRP lock, which is almost impossible to get around without an account password.
⚠️ Warning: After resetting through Recovery, the second space will be destroyed, and you can only recover files from it if you have synced with Mi Cloud or made a local copy before blocking.
Third-party tools and their effectiveness
There are many programs on the Internet that promise to hack into a second space or reset a password without losing data. Most of them, like various Android Unlockers, exploit vulnerabilities in older versions of Android. On modern devices with updated security, their effectiveness tends to zero.
Using such software carries serious risks: first, you can transfer your data (including account passwords) to unknown third parties; second, incorrect interference with system files can lead to the “bricking” of the smartphone when it stops turning on at all.
- 🚫 “Hacking” programs often contain viruses or miners.
- ⚠️ Risk of Bootloader Damage when Using ADB-teammates.
- 💰 Most paid services do not guarantee results on new versions MIUI.
The only legal third-party method is to contact Xiaomi’s authorized service center with a check to buy. Engineers can reflash the device officially, but the data will also be lost. There is no “magic button” to save data when the password of an encrypted container is forgotten.
💡
Using questionable unlock software is a high-risk lottery, with official reset via Recovery being safer and more reliable.
Prevention and safety setting
To prevent a forgotten password from happening again, it is important to set up the security system right after the second space is created. MIUI allows you to link the unlock of the second profile to your fingerprint or face, which speeds up access and reduces the risk of forgetting a complex combination of numbers.
You can use the built-in Mi Backup app to create a copy of the second space on your computer or external drive, and you can also write the password you set to a safe place, in a paper notebook or in a password manager in the main profile, which is always accessible.
Settings -> About Phone -> MIUI version (7 times) -> Developer menu -> Enable debugging over USBEnabling USB debugging (as shown in the code above) may be useful for advanced users to create full backups through ADB, but for the average user, it is enough to configure synchronization with the cloud. Remember that the security of your data depends primarily on your foresight, not on the possibility of emergency recovery.
⚠️ Warning: Do not use the same passwords for the main and second spaces. If an attacker gains access to one, they will automatically gain access to the second space.
