Xiaomi’s modern smartphone stores a huge amount of sensitive information, from banking apps to personal photos, so reliable device protection becomes a critical task for every owner. Standard factory settings often offer basic security options that are easy to guess or bypass, making the password change one of the first steps after buying a gadget. In this article, we will examine in detail all aspects of password management in the shell of MIUI and the new HyperOS, paying special attention to nuances that are often overlooked by even experienced users.
The process of changing the access code can be required in various situations, from a simple desire to enhance security to restore access after buying a used device. It is important to understand that there are several layers of protection: screen lock, Mi Account password and pin code. SIM-And we're going to look at not only the standard algorithms, but also the methods for solving problems that arise when systems fail or data is forgotten.
Incorrectly installed protection can lead to locking the device if you forget the complex composite code, so the choice of authentication method should be approached carefully. On devices with Snapdragon 8-series processors and the latest hardware encryption of data depends on the complexity of your password lock screen. Next, we will go through all the necessary settings Step-by-step to ensure that your smartphone remains inaccessible to prying eyes in any conditions.
Password types and levels of protection in MIUI and HyperOS
Before you start changing your settings, you need to clearly distinguish between the types of passwords used in the Xiaomi ecosystem.The system offers flexible tools to protect data, and confusion between them often leads to unnecessary complications.The lock password is the main key you enter when you turn on your smartphone or after the timer expires.
One of the things that I'm talking about is Mi Account, which links the device to your cloud account, and this is anti-theft protection, because even after you completely reset your phone, you'll need to enter your previous owner's login and password, and ignoring this level of security makes it almost useless to have the device re-activated without your account data.

Use different screen lock passwords and Mi Account to minimize the risk of one being compromised.
The third level is the password. SIM-map (PIN-code that is requested by the modem of the phone when booted before operating system start, it protects your SIM card from being used on another device. SIM-If you have a card or paste yours into another phone, you will need this code, which is often set as 0000 or 1234 by default, which is extremely insecure.
Step-by-step: changing the screen lock password
To change the primary password for accessing the smartphone interface, you need to go to the appropriate settings section of the system. The interface may vary slightly depending on the Android version and shell, but the logic remains the same. Open the Settings app and find the section responsible for device security.
Depending on the firmware version, the path may look like Settings → Passwords & Security → Screen Lock or Settings → Lock screen → Security Type. The system will prompt you to enter your current password, pattern lock or fingerprint to verify your identity. Once you have successfully logged in, a menu will open to select a new security method.
☑️ Change of lock password
Here you can choose between a pattern lock, PIN-A mixed password is considered the most reliable, because it increases the number of possible combinations exponentially. After choosing the type, enter the new code twice for confirmation, and the system immediately applies the changes.
It is worth noting that when you change the type of password (for example, switching from a graphical key to a digital one), the system can warn that some biometric data will require re-association, a normal security response to changing fundamental access parameters.
Managing Mi Account Password Management
Mi Account is a central element of Xiaomi’s ecosystem, syncing contacts, notes and data to the cloud. Change passwords are not through phone settings, but through a web interface or the Security app. First, go to Settings → Mi Account → Account Management.
In the menu that opens, select "Security" or "Password" and the system will redirect you to the login page. After you enter the current data, you will be asked to come up with a new combination. The password requirements are stricter here: usually you need a minimum of 8 characters, including letters of different registers and numbers.
⚠️ Note: After changing the Mi Account password, all associated devices (tablets, TVs, other smartphones) will require re-authorization. Make sure you remember the new code, as restoring access to your account is a difficult process.
If you don't remember your current password, use the recovery function via a linked phone number or backup email. Xiaomi will send a confirmation code that will allow you to set a new combination. Regularly changing your account password, at least once every six months, significantly increases the level of protection of your cloud data from unauthorized access.
Set-up and change PIN-code SIM-map
Many users ignore the protection SIM-The card, however, often becomes a loophole for attackers who gain access to the SMS-To get confirmation codes from banks. To set up, go to Settings. → Passwords and security → Confidentiality → Castle. SIM-The path may vary depending on the regional version of the firmware.
In this menu you will see the "Block" switch. SIM-When activated, the system will request the current card. PIN-code (often 0000 or 1234 if you haven't changed it by default) Once you have entered the correct code, the option "Change" will be available. PIN-Enter the current code, then a new one, and confirm it by re-entering it.
| Parameter | Description | Recommendation |
|---|---|---|
| PIN-code | Code to unlock SIM | Change from factory to unique |
| PUK-code | Unlock code when PIN error | Record and store separately from the phone |
| Limit of attempts | Number of inputs before blocking | Usually 3 attempts at a PIN |
| Lockdown | Post-error status | A PUK is required to reset |
Be extremely careful when entering. PIN-^ "Code: After three wrong attempts". SIM-The card will be blocked and will be required. PUK-code. PUK-The code cannot be guessed or selected; it is indicated on the plastic card that came with the SIM card, or in the personal account of your mobile operator.
Biometrics as an Alternative to Passwords
Modern Xiaomi smartphones are equipped with advanced biometric identification modules that allow you not to enter a password every time you unlock. However, periodically the system will still require the input of digital or graphic code.
To set up, go to Settings → Passwords & Security → Fingerprints or Face Recognition. Add your biometrics by following the on-screen instructions. HyperOS offers an Advanced Unlock feature that speeds up fingerprint reading, but can slightly reduce accuracy in rare cases.
Using biometrics is especially convenient when hands are busy or dirty, but in low light or in the presence of damage to the fingers, a digital password remains the only reliable way to log in.
💡
Biometrics speeds up access, but the primary lock password remains the main key to the device’s encrypted data.
What to do if the lock password is forgotten
The situation when the user forgets the password, the pattern lock or.pattern, is one of the most stressful. Unfortunately, modern versions of Android and MIUI for security reasons do not allow you to simply reset your password through a Google account or Mi Account, as it was in older versions of the OS. The only working method is a complete reset of the device to factory settings (Hard Reset).
This procedure will remove all data from the phone’s internal memory, including photos, contacts and apps, if they were not synced to the cloud. To perform the reset, turn off the smartphone, then press the button combination (usually Volume Up + Power) before the Mi logo appears. In the Recovery menu, select the language and tap Wipe Data → Wipe All Data.
⚠️ Warning: Once reset and turned on, the phone will require you to enter a password from Mi Account or Google account that was synced to the device before locking (FRP), Bypass which is impossible without legal means without account data.
If you don't remember your account password, the recovery process can take a long time, so it's critical to always keep the username and password from your main account in memory or stored in a secure place. Attempts to use third-party software to bypass the lock often result in a software failure.
