Xiaomi and Redmi smartphone owners often face the need to change the device access code, which may be due to the desire to strengthen the protection of personal data or because the old code has become too simple and easy to guess. Modern shells MIUI and HyperOS offer flexible security settings to control access to the lock screen.
The procedure for changing the password in the security system of the phone does not require a connection to the computer or complex technical manipulations, all the necessary tools are built directly into the interface of the Android operating system.
In this article, we will take a look at the steps of replacing a pin, a pattern lock, and a password, how to act when the current code is forgotten, and what precautions to take in advance. Competent access management is the foundation of digital hygiene in today’s world.
Types of screen protection in MIUI and HyperOS
Before you start making changes, you need to understand what types of locks your smartphone operating system supports. Xiaomi offers a wide range of options, from simple graphics to complex biometrics. The choice of a particular method depends on the level of protection required and usability.
The most common option is a digital PIN, which can consist of 4, 6 or more digits. Despite its apparent simplicity, a long numerical code provides a high level of crypto-resistance. The alternative is a pattern lock, which requires the points on the grid to be connected in a certain sequence.
More advanced models support fingerprint unlocking or facial recognition, and it's important to understand that these methods often work in conjunction with the master password, so if biometrics fail several times in a row, the system will automatically require you to enter a digital or graphical code.
- 🔢 PIN: A combination of numbers that requires precise sequence input.
- 🔑 pattern lock: Connecting dots on the screen in a given order.
- 👁️ Password: alphanumeric combination of maximum complexity.
- 👆 Biometrics: fingerprint or face scanning (requires a backup password).
⚠️ Note: Using simple combinations like “1234” or “0000” makes your device vulnerable to selection.
Each type of security has its advantages: digital code is entered faster in the cold when removing gloves is impractical; pattern lock is easier to remember visually; however, the system often uses a complex password as a security benchmark to encrypt data on a disk.
Step-by-step: how to change the password
The process of changing the access code takes no more than a minute, if you remember the current password. First, you will need to unlock the smartphone and go to the main settings menu. The interface may vary slightly depending on the version of MIUI, but the logic of actions remains the same for all Redmi models.
Find the security section of your device, and in newer versions of your firmware, it might be called Passwords and Security, or just Security, and that's where all the controls on accessing your gadget are concentrated, and click on "Screen Lock" or "Device Protection."
The system will ask you to confirm your rights by requesting your current password or key, and after successful authentication, a menu will open for selecting a new security method, you can either change the type of lock or simply update the existing code to a more complex one.
☑️ Password change algorithm
Once you have entered the new value, the system will ask you to confirm it by re-entering it, which is a standard procedure that eliminates accidental typos, and remembering the new code is critical, because it will be extremely difficult to restore access without it.

Write down a new complex password in a safe place or use a password manager to keep it in mind in the future.
What to do if you forget your current password
The situation of a user forgetting the access code is one of the most stressful. Fortunately, Xiaomi’s ecosystem provides recovery mechanisms through a Mi Account, which only works if the phone is connected to the Internet and the Find Device feature has been activated in advance.
To reset a forgotten password, go to the official Mi Cloud website from a computer or other smartphone. Log in with the same account that was used on the locked device. From the device management menu, select your Redmi and find the lock or unlock function.
The system will suggest setting a new temporary password that will unlock the screen, and after a successful procedure, it is recommended that you immediately go to the settings and set a permanent code that you will definitely not forget, which does not delete data, but requires a network.
| Method | Internet availability | Data security | You need a Mi Account. |
|---|---|---|---|
| Change in settings | Not required | Save. | Not required |
| Through the Mi Cloud | I'll be sure. | Save. | I'll be sure. |
| Hard Reset | Not required | Removed. | Required for entry |
If the internet on your phone is off, remote reset is impossible, and then you'll have to use more drastic measures that will lead to a complete cleanup of the device's memory, so always keep your mobile data or Wi-Fi on if you're afraid to forget the code.
Why do you need a Mi Account?
Recovery Mode (Hard Reset)
When other methods are not available, the only way out is a factory reset, known as Hard Reset, which completely cleans the internal memory of the smartphone by removing photos, contacts and apps.
To enter recovery mode, turn off your phone. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power button, while continuing to keep the volume. Recovery Mode menu opens.
The navigation in this menu is done with volume buttons, and the choice is confirmed by the power button. You need to find the Wipe Data item and confirm the action. The system will warn you if all data is lost. After the process, select Reboot.
⚠️ Warning: Once reset, the phone will require you to enter a password from a Google or Mi Account that was previously synced (FRP), without the owner's data.
The reset time depends on the memory capacity and the speed of the drive, at which point you should not remove the battery or interrupt the power if the model allows you to do this, as this can damage the system files and “brick” the device.
Once rebooted, the phone will look like a new one you just bought in the store, you'll have to reset your initial setup, connect to Wi-Fi, and enter your account details, and you'll have to download all the apps from the Google Play store.
Setup of biometric protection
Modern Redmi smartphones are equipped with reliable fingerprint scanners located in the on button or under the screen. Customizing biometrics significantly speeds up unlocking, eliminating the need to enter a password every time.
To add a fingerprint, go to the security settings and select "Unlock fingerprint"; the system will ask you to apply your finger several times to the scanner to create an accurate digital cast; it is recommended to add both thumbprints for convenience.
And there's also a face unlock feature that uses a front-facing camera to analyze facial geometry, and although it's less secure than a print, it's easy to access quickly, and biometrics are stored in a secure processor module and not transmitted to servers.
- 👍 Convenience: Unlocking happens instantly when touched.
- 🛡️ Safety: Biometrics are almost impossible to fake.
- 🔄 Reserve: Always have a spare PIN in case of sensor failure.
It is important to update fingerprint data periodically, especially if your fingers have cuts or calluses that can make it difficult to recognize, and it is also worth considering that when you reboot your device, the first input is always through the master password.
Frequent problems and their solution
Users may experience a situation where the phone writes “Too many attempts to enter” or locks itself for a certain time, a security mechanism that prevents the password from being selected by attackers, in which case you just have to wait for the timer to end.
Sometimes the touch screen may not work properly, which prevents you from entering the pattern lock accurately, in which case it is better to temporarily switch to digital input. If the problem is systemic, you may need to update the firmware or reset settings.
Password changes often occur because of complexity requirements. The system may not accept too simple code. Password requirements include minimum length and use of different character types. Compliance with these rules guarantees maximum protection.
💡
Regular password changes and the use of two-factor authentication in your Mi Account significantly improve the overall security of your device.
If you change your password and forget it after 5 minutes, try to remember if you've used a similar combination before. Often, your brain automatically replays old habits. Carefulness when you install a new code will save you time and nerves in the future.
