How to put a lock on the screen of the phone Xiaomi

Protecting your personal data on a modern smartphone is not just a recommendation, but a necessity, especially given the amount of sensitive information stored in Xiaomi devices. Owners often wonder how to properly configure screen protection to prevent unauthorized access to correspondence, banking applications and a gallery. The process of installing a password or pattern lock in the shells of MIUI and HyperOS can seem confusing due to the abundance of settings, but a competent configuration will take only a couple of minutes.

In this article, we will take a look at all the available methods to protect your Xiaomi, Redmi or POCO. You will learn not only about standard pin codes, but also about biometric methods such as face unlock or fingerprint. We will also touch on the topic of smart locking, which allows you not to enter a password when you are in a trusted place. The security of your device begins with the first step – installing a reliable barrier on the lock screen.

Sometimes users ignore basic settings, relying on the lack of interest of attackers in their gadget. This is a misconception, since data theft or access to banking applications can occur even without the physical theft of the phone. A properly configured security system gives confidence in the safety of your digital assets. Below is a step-by-step guide to help you secure your smartphone.

The main types of screen locks in MIUI and HyperOS

Before you start setting up, you need to understand the available options.The Android system, which is the basis of the shell Xiaomi, offers several layers of protection, each of which has its advantages and disadvantages. The choice of a particular method depends on how often you use your phone and what level of security you require.The standard set includes a pattern lock, PIN-code.

A pattern lock is a combination of dots on a screen in a particular order, a visually clear and quick way to unlock that many users prefer to numerical codes. However, cybersecurity experts note that graphic keys often leave traces on the screen or are guessed by the glow of the matrix in the touching areas, and the difficulty of finding such a key depends on your ingenuity in creating it.

PIN-A code is a digital password, usually consisting of 4 or more digits, and is considered more reliable than a simple graphical pattern, especially if the code is long and does not contain obvious sequences like "1234". Password is the most reliable option, as it can include letters, numbers and special characters, which makes it almost impossible to brute-force attacks.

• 🔑 pattern lock – convenient for quick access, but less reliable due to traces on the screen.
• 🔢 PIN-Code – the optimal balance between the input speed and the level of security.
• 🔒 Password is the maximum protection, but requires more time to enter each time.
• 👆 Biometrics – a fingerprint or face ID For instant unlocking after entering the main password.

It is important to understand that biometrics (fingerprint or face) do not replace the main password, but only complement it. The system will always require you to enter digital or graphic code after restarting the device, so you can not forget the main method of unlocking. Backing up passwords in a safe place is a good habit for any user.

Installation of a pattern lock or PIN-code

The process of installing protection on the Xiaomi screen is standardized, but the location of menu items may vary slightly depending on the version of the shell. First of all, you need to get to the main menu of system settings. This can be done through the gear in the notification curtain or by finding the corresponding application in the list of all programs.

Once you enter the settings, find the security section. In newer versions of MIUI, it is often called Passwords and Security, and in older versions it can be simply called Screen Lock. This is where all the tools for controlling access to the device are located. The system will prompt you to choose the type of lock you want to activate as the main one.

Selecting the desired option (for example, PIN-The code will ask you to type the desired combination of numbers, the system will ask you to enter it twice to confirm it, to eliminate the input error, if you choose a pattern lock, you will need to swipe twice to the desired points. After that, the system may suggest configuring additional settings, such as displaying notifications on a locked screen.

⚠️ Note: Do not use simple combinations such as date of birth or the sequence "0000"; these codes are selected by attackers primarily when physically accessing the device.

Once installed successfully, the system may offer to link a Xiaomi account (Mi Account) to allow you to restore access in case of loss of password. This is an important step that should not be ignored. Account binding allows you to remotely control the device or reset your password through the web interface if you forget the unlock code.

Setup of biometric protection: fingerprint and Face ID

Modern Xiaomi smartphones are equipped with advanced biometric sensors that make the unlocking process almost invisible to the user. fingerprint scanning is built into the on button or located under the screen, depending on the model of the device.

To add a fingerprint, go to the Passwords and Security menu and select "Unlock by fingerprint." The system will ask you to apply your finger to the scanner several times, changing the angle of inclination to read the picture more accurately. It is recommended to add both thumbprints, since we hold the phone differently depending on the situation. The quality of the reading depends on the accuracy of the initial calibration.

Face Unlock uses a front-facing camera to scan facial features. Although less secure than a fingerprint (since the owner's photo can theoretically be used to trick you), it's extremely handy. Face ID settings allow you to enable the "Lift to unlock" option, which activates the screen when you pick up the phone.

• 👍 Add prints of both hands for ease of use in all situations.
• 👁️ Face ID It works fast, but may not work in bright sunlight or in complete darkness without IR illumination.
• 🔄 Regularly update biometric data if you change the protective glass or film that affects the scanner.

It is important to note that biometrics does not work after the device is fully restarted, in which case the system will require the primary password to be entered, PIN-The code or pattern lock you installed earlier is a standard security measure for the Android operating system that can't be circumvented software without data loss.

Smart locking and trusted devices

Smart Lock allows you to automate the unlocking process in certain use cases, for example, you can set your phone to remain unlocked when you are at home or connected to your smartwatch via Bluetooth, eliminating the need to constantly enter a password in a secure environment.

To activate this feature, look for the "Smart Lock" or "Smart Lock" option in the security settings. The system will prompt you to choose the type of trusted location, device or voice recognition. When choosing a trusted location, the phone will use geolocation to determine your location within the range of a given point. Access automation greatly improves the comfort of using the smartphone.

You can also add trusted Bluetooth devices, like a fitness bracelet or car radio. While the phone "sees" the paired device, the lock screen will not require confirmation. This is especially convenient for drivers who need to quickly access the navigator or music. However, it is worth remembering that Bluetooth range is limited, and when you move away from the signal source, the phone will again lock.

⚠️ Warning: Do not use Trusted Places in high-traffic public locations. Attackers can take advantage of keeping your phone screen open.

Another interesting feature is voice recognition, which you can customize to say a phrase that unlocks the device, but it's considered the least reliable method, because voice can be recorded or simulated, and it's recommended to use it in conjunction with other defense methods or just for basic actions.

Comparison of protection methods and their reliability

Choosing a locking method is often a trade-off between convenience and security, and to help you decide which option is right for you, we’ve compiled a comparison table of the main protection methods available on Xiaomi smartphones, which will help you assess the pros and cons of each method.

As you can see from the table, biometrics are the best in speed and convenience, but require a primary password for initial activation. A complex password provides the highest protection, but its daily use can be annoying. A pattern lock remains popular due to the user's habit, although it is inferior in reliability to digital counterparts.

💡

The best strategy is to use a complex one. PIN-code or password as a basis, supplemented by fingerprint unlocking for everyday use.

Don’t rely on one method alone if you store critical data on your phone. Combining methods (master password + biometrics) creates layered security. A comprehensive security approach minimizes the risk of data leakage even if the device is lost.

What to do if you forget your lock password

It's not uncommon for users to forget their password or graphical key, unfortunately, modern versions of Android and MIUI shells have a high degree of protection, making it almost impossible to bypass the password without losing data, and this is done specifically to protect the owner's information from unauthorized persons.

If you have attached a Mi Account and enabled Find a Device, you can try resetting your password remotely via i.mi.com. You need to log in to your account, select a locked device, and use the option. However, this method does not work on all firmware versions and requires pre-setting. Account reset is the most gentle way to solve the problem.

In most cases, the only way out is to completely reset the device to the factory settings (Hard Reset), which will delete all user data, including photos, contacts and apps, but return access to the phone, usually via Recovery Mode, clamping the combination of volume and power buttons when the device is turned off.

To avoid future data loss, back up your important information regularly in the cloud or on your computer. Google and Xiaomi Cloud automatically sync contacts, notes and settings. Backup is the only guarantee that you won’t lose important data in an emergency reset.

⚠️ Warning: Once reset to factory settings, the system will require you to enter a password from a Google account or Mi Account that was previously synced to the device (FRP), which cannot be circumvented by simple methods.
