Modern smartphones contain huge amounts of sensitive information, so protecting access to the device is a priority for every owner. The lock screen on Xiaomi gadgets running MIUI or HyperOS shell is a powerful tool that not only protects personal data, but also allows you to personalize the appearance of the interface.
In this article, we’ll take a look at all aspects of security configuration, from choosing a password type to setting up smart features like face unlock or fingerprint. You’ll learn how to change standard settings, set lock timeouts, and even add widgets to quickly access important features without fully unlocking your phone. Understanding these settings will help you find a balance between usability and reliable protection.
MIUI offers a wide range of customization capabilities that often remain hidden from ordinary users. Xiaomi regularly updates its security algorithms, introducing new methods of biometric authentication. We will look at current methods for installing protection that will be suitable for both new flagships and more budget models of Redmi and Poco.
The main types of protection and their comparison
Before you start setting up, you need to decide on the default authentication method, which offers several options, each with its own advantages and disadvantages depending on the use cases, choosing the right type of protection directly affects the speed of access to the device and the level of security of your data.
The most common and versatile method is the pattern lock, which is convenient for quick input, as it does not require switching layouts or memorizing complex combinations of numbers. However, studies show that simple graphic patterns (such as the letter "L" or "Z") are easily readable on bold marks on the screen, which reduces their reliability in crowded places.
Digital. PIN-A code or a complex password provides a much higher level of protection. Using a combination of 6 or more characters, including letters and numbers, makes brute-force key selection almost impossible for attackers. MIUI have built-in input delay mechanisms after several failed attempts, which further complicates hacking.
⚠️ Warning: Using simple passwords like "1234" or "0000" makes your defenses almost useless.
Biometric methods like fingerprint scanner and facial recognition combine high speed and reliability. Xiaomi smartphones use both capacitive scanners built into the power button or screen, and more advanced systems. It's important to understand that biometrics is convenient, but in some jurisdictions, a password may be legally more secure than a fingerprint.
Step-by-step setting a password or pattern lock
The process of installing protection in the MIUI shell is standardized, but it has its own peculiarities depending on the version of the operating system. First, you need to go to the main menu of the device settings, and this can be done by clicking on the gear icon on the desktop or in the notification curtain.
The algorithm of actions is as follows:
- 🔒 Find and select the Passwords and Security section in the Settings menu.
- 🔑 Click on Screen Lock or Device Protection.
- 📱 Select the preferred type of lock: pattern lock, PIN-code.
- ✍️ Enter the selected combination twice to confirm.
Once you set the primary password, the system will suggest setting up additional settings, such as displaying the contents of notifications on a locked screen, so you can hide sensitive messages by leaving only the sender's name, or disable preview completely, an important step to preserve privacy in public places.
☑️ Password security check
It is worth noting that when you install a new type of lock, the old one will be automatically replaced. If you have previously used a fingerprint, when you change the main password, the system may require re-registration of biometric data to synchronize the encryption keys.
Set up biometric unlocking
Biometric authentication on Xiaomi devices works at a high level, providing fast application opening and payment confirmation. To set up your fingerprint, go to the Passwords and Security menu and select Unlock by fingerprint. The system will ask you to put your finger several times to the scanner, fixing different edges and centers of the pad to create an accurate digital cast.
The Face feature ID (Face unlocking on many models Xiaomi uses front-facing camera and artificial intelligence algorithms to build 3D-It allows the phone to recognize the owner even in low light. 2D-Unlocking (without infrared illumination) is less secure than a fingerprint scanner and can be fooled by a quality photo.
⚠️ Attention: When using face unlock in the dark, the screen can flash brightly. If you are sensitive to light, it is best to use a fingerprint at night.
Biometrics also offers Additional Features, where you can activate Double tap to wake or lift your device, which greatly speeds up access to the interface, making smartphone use more comfortable. Remember to periodically remove old prints and add new ones if your finger has been damaged or contaminated.
💡
Add the same finger twice under different names (e.g., "Finger L" and "Finger L-2") to increase the scan area and speed up the unlock.
Smart locking and special features
MIUI offers a Smart Lock feature that allows you to automatically disable password requests in trusted situations. For example, you can set your phone so that it doesn’t need to be unlocked when connected to your home Wi-Fi network or is next to a paired smartwatch or Mi Band fitness bracelet.
To activate this function:
- 🏠 Go to Settings. → Passwords and security → Confidentiality.
- 🔓 Find the Smart Lock section).
- ✅ Select the condition: Safe Place, Safe Device or On the Body.
Smart locking greatly improves the user experience of the device in everyday life, you do not have to constantly enter a password at home or in the office, but be careful: if you lose your phone in a “safe place”, an attacker will have full access to data without the need to select a code.
| Type of smart locking | Principle of action | Level of risk |
|---|---|---|
| Safe place. | Disables the password in the radius of the Wi-Fi router | Medium. |
| Safe device | Works when connected via Bluetooth | Low. |
| On the body. | Keeps unlocked while sensors record movement | High-pitched |
| Voice trust. | Unlocking by command "OK, Google" | High-pitched |
It’s important to check the list of trusted devices and places regularly. If you’ve sold an old Bluetooth headphone or changed your router, be sure to remove those devices from the list of trusted devices in Smart Lock settings to avoid creating a security breach.
Personalization of the lock screen and widgets
The lock screen is not only a security barrier, but also an opportunity for self-expression. In Xiaomi, you can change wallpaper, fonts and add useful widgets. To change the background, go to Settings → Wallpaper and select an image from a gallery or online directory. Dynamic wallpaper can come to life when you click, adding interactivity.
One of the unique features of MIUI is the Wallpaper Carousel, which automatically changes images on a locked screen, showing beautiful photos with brief descriptions. To activate it, go to the theme or wallpaper settings and turn on the wallpaper carousel switch, and you can select categories (nature, technology, art) and frequency of image changes.
How to turn off advertising on the lock screen?
You can also display pedometer widgets, weather, notes, or music controls on the lock screen, and new versions of HyperOS have the ability to change the size and position of the watch, as well as add shortcuts to run a flashlight or calculator with a single swipe, which turns a locked screen into a full-fledged information bar.
💡
A wallpaper carousel is a great way to refresh the phone’s visual style, but it can consume extra battery power when new images are loaded frequently over the mobile network.
Solution and resetting of settings
Sometimes users are faced with situations where the lock screen is not working correctly: the sensor reacts with a delay, the fingerprint is not read or the password is not accepted. First of all, try to restart the device. Often temporary failures in the operation of Keyguard system services are fixed by a simple restart.
If the problem is that the phone won't recognize your finger, try cleaning the scanner of fat and moisture. Also, in the fingerprint settings, you can remove the old cast and register your finger again, paying attention to the edges. In rare cases, resetting network settings or updating the system to the latest version through Settings → Phone helps.
⚠️ Warning: If you forget your lock password, the only way to get your phone back is to reset it completely to the factory settings (Hard Reset), which will delete all data if you don’t have a backup in your Mi Cloud or Google account.
To perform the reset via Recovery Mode:
- 📴 Turn off the smartphone completely.
- 🔘 Press the Volume Up button and Power at the same time.
- 🔄 Wait for the Mi logo to appear, then release the power button while continuing to keep the volume up.
- 🧹 In the Recovery menu, select Wipe Data → Wipe All Data (use volume buttons for navigation and power button for confirmation).
Once reset, the phone will request a Google account or Mi Account that was previously synced to the device, an Action Lock measure, which is impossible to use without knowing your account password, so always remember your credentials.
