Protecting personal data in a modern smartphone is becoming the number one priority for every user. Set a password on a Xiaomi phone is the first and most important step to ensure the privacy of your correspondence, photos and banking applications. Mi and Redmi device owners often underestimate the importance of basic security settings, relying only on a fingerprint scanner, which does not always work correctly.
MIUI, and now HyperOS, offers flexible screen locking tools to help you choose the method you want to use, such as classic digital code, complex graphics, or even facial recognition, and in this article, we’ll take a closer look at the process of activating protection, look at the nuances of each method, and answer frequently asked questions.
Don’t ignore this stage of setting up, as losing your device or accessing an unlocked gadget can lead to serious financial losses.We will help you figure out what type of protection is right for your use case, and how to avoid typical errors when creating an access code.
Choosing the optimal type of screen lock
Before you go directly to the settings, you need to decide on the method of protection. Android security based on shells from Xiaomi offers several options, each of which has its advantages and disadvantages, the choice depends on how often you are willing to enter the code and what level of protection you need.
The simplest option is a pattern lock, which is a connection of points on the grid. 3x3. This method is convenient for those who do not remember numbers well, but it is quite easy to peek from the outside if you often unlock your phone in public places. PIN-code 4-6 numbers that are more difficult to reproduce visually by observing the movements of the fingers of the owner.
- 🔒 pattern lock – convenient to draw, but easy to peek (around).
- 🔢 Digital. PIN — Classical method balancing speed and reliability.
- 🔣 A complex password is the maximum protection that requires entering letters, numbers and symbols.
- 👁️ Face ID — Quick face unlock, but less safe with twins or photos.
For maximum protection, experts recommend using a mixed password that includes letters and numbers, but this can be inconvenient for daily use. Business account owners or people who store critical information often choose this option, despite the increase in the time to unlock the device.
Step-by-step instructions for setting a password
The process of installing protection on Xiaomi devices is standardized and takes no more than a minute. You need to get to the main system settings menu, where all device management options are located. The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic of actions remains the same for all models.
Find and open the Settings app, then scroll down to the Passwords and Security section. That's where all the access control tools are concentrated. Click on Device Protection, and then the system will prompt you to choose one of the available screen lock methods.
☑️ Password setting algorithm
After choosing the type of protection, for example, PIN-If you want to do this, you will be asked to enter the combination twice to confirm it, and try not to use obvious dates, such as your birthday or your birthday, as they are easy to guess. The system may also suggest enabling the “Show Password” feature when you type in, which is convenient when you first set up, but less secure when you’re not in the system.
⚠️ Warning: Once you have a password set, the system will ask for a Mi Account or Google account to be linked, which is a critical step: without a linked account, it will be almost impossible to restore access to the device after a forgotten password.
The final step is to set up additional settings, such as the time to automatically lock or the ability to unlock through a smartwatch, make sure all settings are applied correctly, lock the screen with the power button, and try unlocking the device with a new code.
Setup of biometric protection and Face ID
Modern Xiaomi smartphones are equipped with advanced biometrics modules that significantly speed up access to the system. The fingerprint scanner can be located on the back, be built into the power button on the side, or even be under the screen in flagship models.
To add a fingerprint, go to the Passwords and Security menu 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 the same finger twice as different fingerprints, which will increase the likelihood of successful unlocking in difficult conditions.
| Protection method | Speed of operation | Reliability | Convenience |
|---|---|---|---|
| Fingerprint. | Tall. | Tall. | Very comfortable. |
| Face ID (2D) | Medium | Low. | Comfortable. |
| PIN-code | Low. | Medium | Requires input |
| pattern lock | Medium | Low. | Habitual. |
Face technology ID On most smartphones, Xiaomi uses a front-facing camera to create 2D-It's faster than a password, but it's less secure than a fingerprint, because you can fool the system with a good photo, but it's a great option for everyday use with a master password.

Blocking individual applications
One of the unique features of the MIUI shell is the ability to set an additional password to run specific applications, which is indispensable if you want to hide the contents of the gallery, correspondence in instant messengers or access to banking applications from prying eyes, even when the phone is unlocked.
To activate this feature, you need to log in to the Application Protection section in the security settings, the system will prompt you to create a separate password or use an existing screen unlock pattern, and then you can select from a list all the installed programs that require additional protection when running.
When you try to open a secure application, such as Telegram or Gallery, your smartphone will request confirmation through a fingerprint or code entry, creating a double security loop: even if an attacker gains access to the desktop, important data will remain unavailable without a second key.
⚠️ Warning: Don't set the same passwords for locking your screen and for protecting your apps. If the primary password is compromised, an attacker will have access to all levels of protection on your device instantly.
In the same section, you can configure Hiding Apps, where the program icon disappears from the desktop and is only accessible through a dedicated command in the “call” or search, which provides an even higher level of privacy for the most important data on your device.
What to do if you forget your password
It's quite common for a user to forget a set access code, unless you have attached a Mi Account account or set up an answer to a secret question, restoring access can be a difficult task, but if an account has been added, the password reset process goes quite smoothly.
After five failed attempts to enter a password, a countdown timer and a "Forgot the password" button will appear on the screen, and by clicking on it, you can log in to your Mi or Google account, and then the system will allow you to set a new combination, which is the only way to reset the code without losing data.
💡
Write your password in a safe place or use a password manager. Human memory is prone to errors, especially when you need to remember many different codes for different services and devices.
If your account is not tied or your password is forgotten, the only option is a full Hard Reset, which will remove all data from the phone’s internal memory, including photos, contacts and apps, returning the device to a “store-like” state.
Volume Up + Power button (hold until vibration)To do the reset, you need to turn off the phone, then press the button combination to enter Recovery mode. From the recovery menu, select "Wipe Data", confirm the action and wait for the process to end. After the reboot, the phone will be clean, and you can set a new password.
