Protecting personal data on a modern smartphone is a priority for every device owner. Owners of gadgets from Xiaomi, Redmi and Poco often face the need to improve security or simply replace a forgotten code with a more convenient one. MIUI operating system and its global version HyperOS offer flexible tools for access control, but the settings interface can vary from version to version.
Changing your screen lock password is not just a formality, but an important step in keeping your information private. PIN-code or standard pattern lock, the risk of unauthorized access increases significantly. In this article, we will discuss in detail all ways to change security combinations, and also consider the actions in case of loss of access to the device.
It is worth noting that the setup process may vary depending on the version of Android and the specific model of your smartphone. Some older models may not support biometric unlocking, relying solely on digital or graphical methods. Understanding these nuances will help avoid errors and save access to important applications and files.
Types of screen protection on Xiaomi smartphones
Before you move on to changing your password, you need to understand what types of protection MIUI offers. The choice of locking method directly affects the level of security and usability of the device in everyday life. Modern Xiaomi smartphones provide a wide range of options, from simple swipes to complex biometric data.
The most common and convenient method is facial unlocking or fingerprinting, but these methods always require a backup method of entering in case of sensor failures or battery discharge, which is why installing a reliable digital or graphic code is a prerequisite for activating biometrics.
System constraints dictate specific rules for each type of protection, such as a pattern lock that connects a minimum of 4 points, and a digital password often requires at least 6 characters to improve resistance to selection, PIN-The code and fingerprint scanner create a double barrier for abusers.
- 🔒 pattern lock: connecting points on the grid 3x3 in a certain order, convenient for remembering visually.
- 🔢 PIN-code: a sequence of 4 or more digits, a classic and reliable method of protection.
- 🔣 Password: A combination of letters, numbers and special characters, provides the highest level of cryptographic resistance.
- 👁️ Face unlock: Quick scan through front camera, convenient but less safe in the dark without IR backlight.
Step-by-step instructions for changing the password
The process of changing the lock password in the MIUI shell is quite logical, but it requires careful input of new data. To start the procedure, you need to access the device settings menu. If you know the current password, there will be no problems, and you can quickly update the security data.
To start, open the Settings app and find the security section, which can be called Passwords and Security or just Security, and within that menu, select Device Security, where all key access options are stored.
☑️ Checklist before changing password
Once you log in to the Device Protection menu, the system will require you to confirm your rights by asking you to enter your current password or attach your finger. Next, select Lock Screen or Screen Protection Type. Here you will be asked to choose a new security method or change an existing one. Follow the on-screen prompts by entering the new code twice for confirmation.
⚠️ Note: When changing the type of protection (for example, from a pattern lock to a pattern lock) PIN-code, the system will automatically delete old biometric data (fingerprints and facial data) for security purposes, and you will need to reconfigure it after changing your password.
The system may suggest enabling the "Show Password" feature when you type in to avoid errors due to typos. After a successful code change, the phone may require a reboot or re-authorization in your Google account.
What to do if I forget the lock password
A situation where the owner forgets the password, pattern lock or PIN-Unfortunately, modern versions of Android and HyperOS have significantly limited the ability to restore access without losing data. Techniques that worked years ago, such as entering code through a Google account after several failed attempts, often don’t work in new versions or require pre-configuration.
If you have linked your Mi Account and enabled Find a Device, you have a small chance of unlocking your phone remotely, by going to the official Xiaomi cloud service website from another device, entering your details and selecting an unlock option, but this method only works if you have an active Internet connection on a locked smartphone.
Why can’t you just reset your password without losing your data?
In most cases, the only way out is to completely reset your device to the factory settings (Hard Reset), which will delete all user data, photos, contacts and apps, returning the phone to the “out of the box” state. Before starting the procedure, make sure you remember the data from your Google or Mi Account, as after the reset, the system will require them to confirm ownership (FRP protection).
| Method of recovery | Data retention | Conditions required | Difficulty |
|---|---|---|---|
| Through the Mi Cloud | Yes. | Internet, enabled search function | Low. |
| Smart Lock (Google) | Yes. | Location in a trusted location/device | Low. |
| Recovery (Wipe Data) mode | No. | Physical access to buttons | Medium |
| Service centre | No. | Purchase papers, check | Tall. |
Resetting through Recovery mode
If remote unlocking is not possible, you will need to use hardware buttons to enter recovery mode, a method that is universal for most Xiaomi, Redmi and Poco models. First, turn off your smartphone completely. Then press the volume button and the power button simultaneously.
Hold the buttons until the Mi logo or Recovery Mode appears. In this mode, the touchscreen does not work, so the navigation is done with the volume buttons (up/down), and the choice is confirmed by the power button. You need to find the item "Wipe Data" or "Clear Data".
Once you select a data reset point, the system may request confirmation, often requiring you to type in the word "yes" or simply confirm the action. The formatting process will take a few minutes. Upon completion, select "Reboot" to restart the device. The phone will turn on as new, and you will have to reset the original setting.
💡
Tip: Before selling or transferring your phone to another person, always do a complete data reset via the settings menu, not just through Recovery, to make sure that you delete your accounts correctly.
And you have to remember that, after that reset, FRP (Factory Reset Protection) is a Google security mechanism that requires you to enter a password from an account that was synced to your phone before the reset, and if you don't remember that, it's going to be very difficult to unlock the device even in a service center without a check.
Smart Lock Unlocking Smart Lock
To avoid constantly entering a password in secure places, you can use the Smart Lock feature, which allows you to automatically turn off the screen lock under certain conditions, for example, when your phone is in your hand, at home or connected to a Bluetooth headset.
You can find this setting in the Passwords and Security menu -> Device Protection -> Smart Lock (or Lock with Help). The system will offer several scenarios, such as Trusted Places using GPS to determine your location, and Trusted Devices responding to the connection of a smartwatch or headphones.
Using a Smart Lock greatly improves the comfort of your smartphone, but reduces overall security.If you lose your phone within a “trusted location” or with Bluetooth enabled, anyone will have access to your data, so this feature should be used with caution.
- 🏠 Trusted Places: The phone unlocks when you are within range of your home Wi-Fi or within a specific geopoint.
- ⌚ Trusted devices: The screen stays open while the smartphone is Bluetooth connected to your fitness bracelet or car tape recorder.
- 🗣️ Voice recognition: Unlocking occurs by voice command (less reliable as voice can be recorded).
- 🤲 Handhold: Sensors detect that the phone is in motion or held, and do not lock the screen (on a limited time).
Frequent problems and their solution
Users often experience a situation where the touch screen stops responding when the password is entered, which may be due to software failure or contamination of the screen surface. First of all, try to wipe the display with a dry soft cloth and remove the protective glass, if any.
Another common problem is the endless reboot cycle after changing the password, which can indicate a conflict of system files or an error in the security module, in which case it helps to download to Safe Mode or reset settings through Recovery.
💡
If the touchscreen doesn't work at all, connect a USB-OTG adapter and a regular computer mouse, which will allow you to enter a password and unlock the device to make a backup of the data.
Also worth mentioning is the latency problem, which is that after a few missteps, the system blocks input for 30 seconds, then 1 minute and then up, which is normal code protection, and don't try to guess the password during this period, because the timer is reset with each new error.
⚠️ Warning: Do not use third-party apps from unverified sources that promise to “hack” or bypass Xiaomi’s password. at best they will be useless, at worst they contain viruses or spyware that will steal your data.
If none of the software methods work and the phone continues to behave incorrectly, it may be the hardware that is the problem, and damage to the display plume or power controller can mimic software errors, and in such cases, it is recommended to contact an authorized service center for diagnosis.
