Xiaomi’s smartphone stores a vast amount of personal information, from instant messaging to accessing bank accounts. Data protection becomes not just an option, but a necessity for every device owner. Set a password or biometric key is the first and most important step to ensuring the digital security of your gadget, without which anyone who takes your phone in their hands will have access to all applications and files.
MIUI and the new HyperOS have flexible access customization tools, you can choose a simple graphical pattern, a robust digital code, or biometrics. It's important to understand that Xiaomi's security system allows you to combine these techniques for maximum protection, for example, face unlock can be used for quick login, but you will need a fingerprint confirmation to pay.
In this article, we will take a look at all the available ways to restrict access, how to configure different types of passwords, how to use hidden functions, and how to manage access rights in different use cases, and how to use them in a new flagship and budget model of the brand.
The main types of blocking and their features
Before you start setting up, you need to decide on the type of protection that will be most convenient in your situation. The standard set of options in the security menu offers several options, each of which has its advantages and disadvantages. The choice depends on which is more important to you: the speed of unlocking or maximum cryptographic strength of the password.
The most common method is the pattern lock, which is convenient because it is easy to remember with muscle memory of the hand, but studies show that simple patterns (such as the letter "G" or "Z") are easy to peek from the side or reconstruct from fat marks on the screen. A more reliable option is PIN-It's a code that's made up of numbers. The longer the code, the harder it is to pick it up, but you type it in. 6-8 The numbers can take time every time.
⚠️ Warning: Using simple passwords like "1234," "0000," or dates of birth makes protection virtually useless.
Modern Xiaomi smartphones also offer mixed passwords that include letters and characters, which is the most secure format, but using it on a mobile device is often uncomfortable due to the need to constantly switch the keyboard layout. For everyday use, the optimal balance is considered a complex pattern lock or PIN-6-digit code combined with biometrics.
Step-by-step setting a password or pattern lock
The activation process starts with logging into the main settings menu. MIUI may vary slightly from one version to the next, but the logic remains the same. You'll need to find the section that handles screen and lock settings, usually at the top of the list of basic settings or in the System group.
When you go to the desired partition, the system will suggest you choose the type of lock, which is critical, because you can change the type of password later, but you have to reset the old one. If you choose a pattern lock, a 3x3 grid will appear on the screen. Put your finger on a line connecting the dots. The line should not cross itself unless it is provided by the chosen mode, and should connect at least 4 dots.
☑️ Setting up the lock screen
After the first input, the system will ask you to confirm the action, enter the key or draw the pattern again. If the data match, a notification of successful activation will appear. From this point, the lock screen will activate automatically after the wait time has expired or when you press the power button, and the system may offer to link the Xiaomi account to restore access in the event of loss of the password.
It is important not to confuse the lock password with the password from the Google account or Mi Account. These are different levels of protection. The screen password protects physical access to the device, while the account syncs data in the cloud. It is recommended not to use the same combinations for these purposes, so that the compromise of one element does not lead to a complete hack.
Setup of biometric protection: fingerprint and face
Biometrics provide the fastest and most convenient access to the device. Xiaomi smartphones support fingerprint scanners located both on the back and built directly into the display. Face ID algorithms allow you to unlock the phone just by looking at it. Customizing these features greatly speeds up the work with the smartphone.
To add a fingerprint, go to the Passwords and Security menu and select the appropriate item. The system will ask you to repeatedly apply your finger to the scanner, slightly changing the angle of inclination. This is necessary to create an accurate digital map of papillary lines. It is recommended to add both fingers so that you can unlock the phone with the hand in which it is currently in.
| Type of biometrics | Speed of operation | Reliability | Conditions of work |
|---|---|---|---|
| Print (side) | Tall. | Very high. | Works in the dark. |
| Print (in screen) | Medium | Tall. | Requires finger-touching |
| Facial recognition | Very high. | Medium | Lights are needed, not working in a mask. |
The face unlock feature uses a front-facing camera and artificial intelligence algorithms to analyze facial geometry. While it's very convenient, it should be remembered that two-dimensional recognition is less secure than three-dimensional scanning. Double-verification (face + password for banking applications) is good practice for protecting financial data.
What to do if the fingerprint scanner is not working well?
Additional settings of the lock screen
In addition to setting the password itself, the system allows you to fine-tune the behavior of the lock screen, which affects what information will be visible without unlocking, and what actions can be done immediately, and a competent privacy setting helps to hide the content of notifications from prying eyes.
You can activate the "Block in your pocket" function in the settings menu, and it uses a proximity sensor to prevent accidental taps when the phone is in your bag or pocket, and it also has a lock option when you remove it. SIM-This is a card that protects the device from flashing or stealing the number, and these security mechanisms make the device less attractive to intruders.
Special attention should be paid to the notifications display setting, so you can choose to hide content mode, where only the name of the application, not the text of the message, is visible on the locked screen, and this is especially true for social networks and messengers, where confidential information may be contained.
⚠️ Note: Smart Unlock allows you to avoid entering a password when connecting to trusted devices (such as Mi Band). Use it with caution, as losing the tracker can open access to the phone.
Another useful option is to display the owner's information on the lock screen, so you can add text with a contact number or a message "Return for a reward" that will be visible even when the phone is locked, which increases the chances of the device being returned in case of loss.
Managing application passwords and second space
Xiaomi’s ecosystem offers a unique feature to protect individual applications, even if the phone itself is unlocked. This is true when you give a phone to a child or colleague, but do not want to show personal photos or correspondence.
To activate, go to the security settings and find "Application Protection" where you can select any software you have installed and put a switch next to it. When you try to open an application like a Gallery or a Bank client, the system will request additional confirmation, which creates a dual security loop within the same device.
💡
Use different passwords to lock your screen and to protect your apps, and if an attacker learns your master password, the second layer of protection will save your most important data.
A more radical method of data isolation is the Second Space feature, which creates a virtual second desktop with its apps, photos and accounts on the phone, switching between the main and second spaces instantly using a fingerprint or password, and is the perfect solution for separating work and personal data on a single device.
So backing up data and remembering all the access codes is critical, and the system has no back door to recover that data without the code.
What to do if the lock password is forgotten
A situation where a user forgets a password, pattern lock or PIN-Unlike older versions of Android, Xiaomi's modern security systems don't allow you to simply reset your password through your Google account without losing data.
The only official way to access a phone without a password is to completely reset to factory settings (Hard Reset), which completely deletes all user data, photos, contacts and applications. Before performing this operation, you need to make sure that you have a backup of important files in the cloud or on your computer.
To perform the reset, you need to turn off the phone and press the combination of buttons (usually a power button and a volume button). In the Recovery menu, select "Wipe Data". Once confirmed, the phone will be cleaned and rebooted as new. You will not need to enter a lock password after that, but the system can request the Google or Mi Account data that was previously associated.
⚠️ Warning: After resetting the settings will work protection FRP (Factory Reset Protection: Without entering the username and password from the Google account that was on the phone before the reset, it will be impossible to turn the device on.
💡
The forgotten lock password on modern Xiaomi can only be eliminated by a complete data reset, and regular backup is the only way to avoid losing information in such a situation.
