The situation when access to your own device Xiaomi is limited due to a forgotten password, is quite common. PIN-codes that were set to protect personal data. MIUI designed to make it as difficult as possible for outsiders to access, but sometimes this creates problems for the legitimate owner of the gadget.
Restoring access depends on whether the screen is locked, the Mi Account password is encrypted, or the data is encrypted in a hidden folder. In some cases, it is enough to enter account details, and in others it will require the complete removal of confidential information. It is important to understand that resetting the Privacy Protection Password without losing the contents of hidden folders is technically impossible without a pre-created backup.
The next steps will depend on the version of the operating system and the model of your smartphone. Modern devices with HyperOS shell or new versions of MIUI have enhanced security protocols that require mandatory binding to the cloud service. Before you start taking decisive steps, carefully consider all available recovery options.
Differences between screen password and data protection
Many users mistakenly believe that the screen unlock password and the privacy password are the same thing, but they are actually two independent layers of security on a MIUI-based Android system. The screen password (pattern lock, fingerprint, Face ID) protects the login, but does not hide the contents of special folders.
Privacy protection is a separate mechanism for encrypting files, photos, notes and apps, and even if you successfully unlock your phone and get to your desktop, access to hidden albums or secure applications will remain closed without entering a special code, and this second layer of protection is often the most difficult to restore.
System requirements for these passwords also vary. Data protection often requires a more complex combination, and it cannot be replaced by biometrics at the time of first access after a device is restarted. Understanding this difference is critical to choosing the right reset method.
- 🔒 The screen password blocks access to the smartphone interface.
- 📁 Data protection password hides specific files and applications inside the system.
- 🔄 Resetting one password does not automatically affect the other.
Using a control issue for discharge
The easiest and most secure way to restore access to protected data is provided by the system itself, if you have set up a check question in advance. When setting a personal data protection password, Xiaomi suggests creating a secret question and answering it. If this feature has been activated, the recovery process will take only a couple of minutes.
You need to go to the security settings menu, enter any wrong password several times until the screen says "Forgot your password?" or a similar prompt. The system will prompt you to enter the answer to the control question. After successfully entering the answer, you will be asked to install a new combination of numbers or characters.
If you don't remember the answer to the control question or you don't set it up, it won't work, and then the security system will consider the access attempt suspicious and require more radical measures. Always try to choose the questions that you won't forget even after a few years.
💡
Write down the answer to the check question in a secure location separate from the phone, such as a paper notebook or password manager on your computer.
Resetting through Mi Account
Xiaomi’s ecosystem is closely integrated with Mi Cloud. If the device has logged in to Mi and synchronization enabled, password protection can be restored via a web interface or account settings, which requires an active Internet connection.
You have to go to the official website of the service from any other device or computer, and after entering your credentials, go to the Device Search or Security Management section, where you can reset local passwords if the device is online and transmits data about the lock status.
However, the company’s privacy policy changes periodically, and newer firmware versions often do not allow for remote resetting of the personal data protection password without data loss to improve security, but checking the status of the account is a must before moving to a full reset.
| Method | Conditions required | Data security |
|---|---|---|
| The checkpoint | Pre-set question | Complete. |
| Mi Account | Active login to the account | Partial / Depends on the version |
| Total reset | Access to Recovery | No (all removed) |
What is Mi Cloud and how does it help?
Completely reset the device via Recovery Mode
If the gentle methods don’t work, the only guaranteed way to access the phone is a full reset, which will delete all user data, including photos, contacts and most importantly, a forgotten password for protecting personal data, and return the device to factory status.
To enter recovery mode, you need to turn off your smartphone completely. Then press the volume button and the power button at the same time. Hold them until the Mi logo or the Recovery menu appears. Some models may require a charging cable connection.
In the Recovery menu, you can navigate with volume buttons and you can choose with power buttons. You can find Wipe Data and select Wipe All Data. You can request confirmation, often requiring you to type in the word yes or select a confirmation in the list. After you complete the process, select Reboot.
☑️ Preparation for Hard Reset
⚠️ Warning: Once reset, the device will request a password from a Google or Mi Account that was previously synced (FRP). If you don’t remember this information, your phone may become unusable.
Removing protection through computer and ADB
For advanced users, there is a method of resetting a password through USB debugging if it was pre-enabled in the developer settings, which allows you to delete the configuration files that store the password hash without fully formatting the user partition, although the success of the method depends on the Android version.
You need to connect your smartphone to a computer with the ADB driver installed. Open the command line and enter the command to go to shell mode. Next, you need to find and delete files that are responsible for protecting privacy, usually in system directories, access to which can be restricted without root rights.
If debugging was not enabled before locking, this method will not work. Attempting to hack the system through bootloader vulnerabilities on modern devices often leads to blocking service functions, so this method is considered more as a theoretical possibility for old models or specific scenarios.
adb shell
cd /data/system/users/0
rm password_key.xml💡
On modern devices with current security patches, removing system password files without root rights is almost impossible, so a complete reset remains the main solution.
Prevention and backup
To avoid losing important data in the future, you need to back up regularly. Xiaomi smartphones have a built-in Backup app that lets you save settings, apps and their data to a memory card or the cloud, the only way to save the contents of hidden folders.
It is also recommended to use the Mi Cloud sync function for gallery and contacts, in which case, even with complete loss of access to the device and the need to reset, you can quickly restore your digital life on a new or cleaned phone.
Write complex passwords in a safe place. Human memory is imperfect, and the 8-10 character combination can be forgotten in a month. Using password managers or a paper notebook stored at home will save you hours of hassle if blocked.
- ☁️ Set up automatic synchronization of important folders with the cloud.
- 💾 Make a local backup on your PC or flash drive once a month.
- 📝 Write passwords from critical functions separately.
⚠️ Note: Backing up hidden albums and secure folders often requires separate confirmation or special export».
