Users of Xiaomi, Redmi and POCO smartphones often face a situation where the built-in security feature blocks access to important data. The application protection system in the shell of MIUI or HyperOS is designed to preserve privacy, but sometimes becomes an obstacle for the owner himself, this can happen when buying a used device, changing an account or banal forgetfulness of a password.
The process of recovering access depends on whether you know the current unlock code or the Mi Account to which the phone is attached. If you remember the data, the procedure takes a couple of seconds through standard settings. However, if access is lost, more radical measures will be required, up to a complete reset of the device. In this article, we will discuss all possible scenarios and ways to solve the problem.
It's worth noting that data security in modern smartphones comes first. Xiaomi engineers have made it difficult to bypass security so that in case of phone theft, attackers can not access your photos and correspondence. So there is no "easy" way to remove protection without losing data or knowing the password - this is a fundamental principle of the system.
Standard shutdown through security settings
If you have physical access to your phone's menu and you know the screen unlock password, the easiest way to do this is to manually disable the feature, and you need to go to the Security system app, which is standard across all the brand's devices, and inside this app is an arsenal of access control tools.
Find the App Lock section, and when you log in, you'll ask for a pattern lock, a digital code, or a fingerprint if you're configured it. Once you've logged in, click on the gear icon in the top right corner of the screen, and that's where the global settings are.
In the menu that opens, you'll see a switch opposite the "Application Protection" option, put it in an inactive position, require you to confirm the action by entering a password or Mi Account, and then all previously blocked programs will be available without additional checks.
⚠️ Note: If you try to disable the security system requires you to log in to your Mi Account and you don’t remember the password, the standard path is closed.
It is important to note that once the feature is disabled, the unlock history and usage statistics will be cleared, which is normal system behavior aimed at protecting the privacy of the previous data owner.
💡
Before disabling protection, take a screenshot of the list of blocked applications, then quickly configure privacy again if necessary.
What to do if you forget your password or pattern lock
Unlike older versions of Android, modern MIUI and HyperOS shells do not allow you to simply reset the application protection password through an answer to a secret question if you did not have an account attached.
If you have a "Forgot Password" button on your lock screen, click on it. The system will prompt you to enter your Mi Account password. This is the main and often the only legal way to reset a forgotten code without losing personal data. Enter credentials, and the protection will be removed automatically.
If the account is also not available or the phone is not connected to the Internet to verify data, there are few options left: you can try to enter Recovery mode and make Wipe Data, but this will lead to the complete removal of all files from the device. The alternative is to log into Safe Mode, but on newer versions of firmware it rarely helps to bypass application protection.
- 🔑 Try to remember if you used the same password for the lock screen and application protection – this is a common practice.
- 📱 Check if fingerprint or face unlock is enabled – sometimes biometrics work even if the digital code is forgotten.
- 🌐 Make sure your device is connected to Wi-Fi or mobile network, as checking your Mi Account requires internet access.
Reset via engineering menu and special codes
Many users are looking for universal codes to log into the engineering menu, hoping to find hidden security settings there. Indeed, combinations like ##6484## or #4636## exist, but they are designed to diagnose hardware and test components, not to manage software locks.
Attempts to use third-party ADB-commands to delete files responsible for protection (com.miui.securitycenter) on modern versions of Android are often unsuccessful.The system has self-defense mechanisms, and without root rights to remove or modify system security components will not work.
Moreover, incorrect interference with system processes through ADB can lead to a cyclic reboot (bootloop).The phone will constantly turn on and off, requiring flashing. Therefore, using the command line to reset the password for application protection is not recommended for users without a deep knowledge of the Android architecture.
adb shell pm disable-user --user 0 com.miui.securitycenterThis team, which you will find on forums, will try to disable the security center. However, on current Xiaomi firmware, this often leads to unstable interface operation, but does not remove the lock from specific applications, since the access permission check is built deeper than the user application level.
⚠️ Warning: Don't download dubious hacking software with the promise of "remove protection in 1 click." 99% of the time, these are styling viruses that will steal your passwords from banking applications.
Full reset (Hard Reset) as a last resort
If none of the gentle methods worked, the only guaranteed way to get back access to the phone is a full factory reset, which will delete all user data, photos, contacts and apps, returning the device to the “out of the box” state.
To do the reset, you need to go to the Recovery Mode menu. Turn off your smartphone completely. Then press the on and volume button at the same time. Hold them until the Mi or Redmi logo appears, then release the power button, while continuing to keep the volume.
In the Main Menu, you can navigate with volume buttons and power buttons. Select Wipe Data, then Wipe All Data, and confirm the action. It takes a few minutes. After you complete, select Reboot.
| Action. | Data retention | Required knowledge | Risk of error |

| Disconnection in settings | Complete. | Minimum | Absent. |
| Reset via Mi-account | Complete. | Average. | Low. |
| Use of ADB | Partial | Tall. | Medium. |
| Hard Reset (Recovery) | No (all removed) | Minimum | Low. |
☑️ Preparation for full discharge
The problem of activation blocking Mi Account
Once you do Hard Reset, you'll come across an activation screen. This is a Find Device security mechanism. The phone will request the username and password from the Mi Account that was synced to the device before the reset. This is anti-theft protection: even flashing it won't help the attacker.
If you have forgotten your Mi Account password, use the recovery form at mi.com or id.mi.com, and you will need access to your linked phone number or backup mail, without which it is almost impossible to unlock your device officially.
There are services to bypass activation locks, but they often require payment, are unstable and may be illegal in your area, and are often closed by Xiaomi’s own security updates.
What is FRP Lock?
Prevention and backup
To prevent a forgotten password situation from taking you by surprise, it’s important to back up regularly.The built-in Mi Cloud app or local backup allows you to save contacts, SMS, call logs, and even desktop settings.
Write your pattern lock or password down to a secure location, like a paper notebook or a password manager on another device, and memory is often a hopeful experience, especially if codes are rarely used, and it's also recommended that you link your phone number and email to your device for recovery.
Check regularly if your Mi Account is active and remembers data from it.This is a key element of Xiaomi's ecosystem, and losing it is tantamount to losing your car keys.
- 📸 Set up automatic gallery sync with Google Photos or Mi Cloud to avoid losing important photos.
- 🔐 Use password managers to store complex combinations that are impossible to remember.
- 💾 Copy important documents to your computer or external drive once a month.
⚠️ Warning: A backup made on a locked phone may prove useless if you can't unlock the device to restore or transfer it.Always check the relevance of backups.
💡
The only reliable way to not lose access is to remember the data from the Mi Account and have an up-to-date backup of the data outside the device.
