Protecting personal data in a modern smartphone is the number one priority for any user, especially when banking applications and confidential correspondence are stored in the device. MIUI operating system and Xiaomi’s new HyperOS offer flexible tools for access control, allowing you to combine different methods of locking the screen. Regular change of access code significantly reduces the risk of unauthorized entry into your device in the event of loss or theft of a gadget.
Many owners of Redmi and POCO devices neglect this step for fear of getting confused in complex settings or accidentally locking the phone. However, the process of changing the password takes only a few minutes and does not require special technical knowledge, if you follow a clear algorithm of actions. In this article, we will discuss in detail all the nuances of changing security codes, and also discuss what to do if access to the settings menu is already lost.
Modern authentication methods go far beyond simple four-digit PIN-Understanding the differences between the unlock password and the Mi Account password is critical, as it can lead to serious problems with access recovery. We will look at both options, focusing on local screen protection, which is the first frontier of protecting your digital space.
Types of screen locks in MIUI and HyperOS
Before you start changing security data, you need to clearly understand what types of locks your smartphone supports. Xiaomi’s Android shell provides a wide range of options, each with its own level of reliability and usability. The choice of the appropriate method depends on how often you unlock the device and how valuable the data stored in it is.
The simplest but least secure method is the pattern lock, which is often chosen by older users. PIN-a code consisting of at least four digits, which is more difficult to pick up by pumping or fingerprinting on the screen. The maximum degree of protection is provided by a full-fledged alphanumeric password, including letters of different registers and special symbols, which makes it almost impossible to crack it by brute force.
⚠️ WARNING: Using simple sequences like “1234,” “0000,” or geometric shapes like the letter “L” makes your phone vulnerable to attackers in seconds.
It’s important to note that modern Xiaomi smartphones allow you to combine these techniques with biometric data. You can use a fingerprint or a face scanner to quickly unlock in everyday life, but when you reboot your device, the system will still require you to enter the basic digital or letter code. This is a fundamental security principle of Android, which is impossible to get around without root rights.
When choosing a new method of protection, consider the ergonomics of your device. On large screens flagships of the Xiaomi 14 or Mix series, it is easier to enter digital code with one hand, whereas on compact models of the Lite series, the pattern lock may be more familiar. However, from the point of view of information security, switching to a complex password is the only right solution for storing important documents.
Step-by-step instructions for changing the password
The process of changing the access code in current versions of the firmware is standardized and takes no more than a minute. You do not need to have superuser rights or connect the phone to a computer, all actions are performed directly through the settings interface. The main thing is to remember the current password in advance, since the system will necessarily require its confirmation before making changes.
To start, open the main menu and find the Settings icon, which usually looks like a gear. In the settings list that opens, you need to find the section responsible for device security. Depending on the version of MIUI or HyperOS, this item may be called "Passwords and Security" or simply "Screen Lock." Going inside, you will see the current security status and the list of available methods.
☑️ Preparation for password change
Once you select the Lock screen, the system will ask you to enter the current security code, which is a precaution to prevent a stranger from changing the settings if the phone is in his hands in an unlocked state. By entering the correct code, you will get access to the selection menu of a new type of lock, where you can switch from the pattern lock to the key. PIN-code.
When you set a new password, the system can suggest you turn on the "Show characters" function, which allows you to see the characters you enter, not the stars. For complex passwords, this is a useful option that reduces the risk of error when you enter. Once you double-confirm the new code (enter twice in a row), the settings will be applied immediately, and the old value will cease to apply.
| Type of lockdown | Difficulty in selection | Ease of input | Recommendation |
|---|---|---|---|
| pattern lock | Low. | High. | For basic protection from children |
| PIN-code (4 digits) | Medium | High. | Not recommended for important data |
| PIN-code (6+ figure) | Tall. | Average. | Optimal balance |
| A complex password | Maximum | Low. | For maximum safety |
If you decide to change the type of lock, such as switching from a pattern lock to a digital code, the system will alert you that old data will be deleted. This is the standard procedure for updating the security protocol. Don't worry, your personal files, photos and applications will remain in place, only the mechanism for accessing the desktop will change.
Change the password of the Mi Account
The Mi Account password, often confused with the screen unlock code, is linked to cloud services, Find Device and data sync. If you change your screen password but forget to update your login details, you may encounter problems when you try to sync or reset your settings.
To change your account password, you need to go to Settings and select the topmost item with your name or avatar. In the Xiaomi account management menu that opens, you need to find the Security or Account Password section. The system will redirect you to the authorization page in the browser or internal security application, where you will need to verify your identity through SMS code or backup email.
⚠️ Warning: Never use the same password for your Mi Account and to unlock the screen.
When you change your Mi Account password, it is important to keep access to your linked phone number or mailbox. Without them, it may be impossible to restore access to your account after changing your password, which will turn your smartphone into a "brick" when you try to reset to factory settings due to activation of the activation lock. Make sure your contact details are up to date.
What to do if your phone number is lost?
After successfully changing your account password, all devices that log in to this Mi Account will require re-authorization, which can cause a temporary break in sync photos or contacts, but this is a normal security reaction. Simply enter a new password in the window that appears on each of your Xiaomi, Redmi or POCO gadgets.
Using biometrics instead of passwords
Entering complex passwords often seems inconvenient, but modern technology allows you to minimize the number of manual inputs. Biometric authentication on Xiaomi smartphones has reached a high level of accuracy and speed. Fingerprint scanners built into the screen or side button recognize the owner almost instantly, even in poor lighting conditions.
To set up the biometrics, go to the Passwords and Security menu and select Fingerprints or Face Data. The system will ask you to enter the current unlock password, then prompt you to apply your finger to the scanner several times or look at the camera. It is recommended to add several fingerprints, for example, for the thumb and index fingers of both hands, so that unlocking is convenient in any position.
Technology 3D-Face scanning is available on flagship models and provides the highest level of protection, as it creates a three-dimensional face map that can not be fooled by a photo. 2D-It's less secure, but it's more convenient for you to access your desktop quickly, and anyway, biometrics doesn't replace your password completely, it just complements it.
💡
Add a fingerprint that you rarely use in your daily life (like your left hand pinky) as an "alarm" fingerprint, and in an emergency, you can unlock your phone with that finger without giving out the primary access code.
It’s worth remembering that biometrics are stored in a secure TEE (Trusted Execution Environment) module of the processor and are not transmitted to Xiaomi servers or the cloud, which ensures that even if you hack a cloud account, your fingerprints will remain safe inside the device, but when buying a used phone, it is better to reset all the biometrics of the previous owner.
What to do if I forget the screen password
The situation when a user forgets a set password or a pattern lock is one of the most stressful. Unfortunately, for security reasons, Xiaomi did not provide a simple “Forgot password” button with a recovery via SMS, as it was in very old versions of Android. The only guaranteed way to return access to the device is a complete reset.
To do the reset, you need to turn your smartphone into Recovery mode. To do this, turn off the device completely, and then press the volume button and the power button at the same time. Hold them until the Mi logo appears, after which the phone will go to the recovery menu. Navigation in this menu is done by volume buttons, and selection is done by the power button.
In the Recovery menu, select a language (usually English or Chinese), then go to Wipe Data and confirm the action by selecting Wipe All Data. This procedure will delete all photos, contacts, apps and settings, returning the phone to the "out of the box" state. After the reboot, you can set a new password, but the old data will be lost forever if there was no backup.
💡
A full reset via Recovery is the only way to remove a forgotten screen password, but it destroys all data on the device's internal drive.
There is also a remote method through the service Xiaomi Cloud, but it only works if the phone was turned on the Internet, activated the function "Find the device" and you remember the password from Mi Account. Once you access the site from a computer, you can send a command to clean up the data, which will also remove the lock screen along with all the information.
Tips for Creating Strong Protection
The security of your Xiaomi smartphone depends on the complexity of the password you choose. Hackers use algorithms that primarily check the most popular combinations, dates of birth and simple sequences. To protect your data, you need to be creative and avoid obvious solutions.
- 🔒 Use a minimum of 8 characters, combining capital and lowercase letters, numbers and special characters.
- 🔒 Avoid using personal information such as birth dates, phone numbers, or pet names that are easy to guess.
- 🔒 Change your password regularly, at least every six months, especially if you have installed apps from unknown sources.
- 🔒 Enable two-factor authentication for your Mi Account so that even if a password is leaked, the attacker does not gain access.
It's a good practice to use password managers that generate and store complex combinations. You only have to remember one master password, and the rest will be done by the software. This is especially true for owners of Redmi and POCO smartphones, who are actively using a variety of online services.
Remember that the screen password is the last line of defense. If the device falls into the wrong hands in an unlocked state, no code will help.So always set up automatic screen lock after a minimum downtime (for example, 30 seconds) and use the Lock in your pocket function so that the phone does not respond to touches inside the bag.
