Modern smartphones store huge amounts of sensitive information, from banking apps to personal correspondence, so reliable screen protection is a critical feature.The standard pattern lock remains one of the most popular ways to lock in the Xiaomi ecosystem, as it combines usability and an adequate level of protection from random access. However, users often face the need to change the combination, whether for security reasons or because the old pattern has become too obvious to others.
With MIUI and the new HyperOS, the process of changing the security code has its own nuances that can confuse an inexperienced user. The settings menu interface changes periodically with the release of new versions of the firmware, and the presence of a Mi Account adds an additional level of verification that many forget. In this article, we will discuss in detail the algorithm for changing the graphical password, consider possible problems and give expert advice on protecting your device from unauthorized access.
Regular password changes should not be ignored, as fingerprints or surveillance from the outside can compromise your security. Properly configured locking is the first and foremost frontier of protecting your personal data in the event of loss of a gadget or theft. Below are the current access control methods that work on most of the brand’s modern models, including the Redmi and POCO series.
Preparation for changing the password and types of blocking
Before you start directly changing your security settings, make sure you understand the differences between the types of locks available in the system. 3x3, It's visually easier to remember than a digital code, but it can be less reliable because of the fatty footprints on the display. PIN-code and complex password are considered more secure options, as they are almost impossible to restore fingerprints on glass.
Importantly, changing the screen lock password automatically changes the password to encrypt the device data if it is activated, which means that without knowing the new combination, access to the file system will not be possible even when you connect to a computer. Android security system in conjunction with the shell from the Chinese manufacturer requires confirmation of the current password before installing a new one, which is the standard procedure for verifying the owner.
💡
Before changing the password, wipe the smartphone screen with a microfiber to remove old fat traces that can prompt the attacker to the previous key drawing.
Make sure your device has a battery charge of at least 20-30% so that your phone doesn’t turn off at a critical time when system security files change. Although the password change process is not energy intensive, a sudden power outage while writing new data to a protected memory area can lead to software errors. It’s also recommended to have your Mi Account data on hand, as the system may require re-authorization after changing critical security settings.
Step-by-step: how to change the pattern lock
The process of changing the security combination in the MIUI or HyperOS shell is unified, but requires careful input. You need to go to the main settings menu, find the gear icon, and select the section responsible for the security parameters of the device. Depending on the firmware version, this item can be called Passwords and Security or simply Security, located at the top of the list or inside the System and Device category.
After entering the menu, select the option Lock screen or Protect the device. The system will require you to enter the current pattern lock, PIN-If you use fingerprint or face unlock, it will not replace the primary password when you change your security settings — that is a requirement of the Android protocol.
☑️ Password change algorithm
In the next step, you will be asked to choose the type of lock. If you want to set the graphic, make sure that the appropriate item is selected, not the one that is used «PIN-Come up with a new combination, connecting at least 4 points, although for increased security it is recommended to use 6 or more points, avoiding simple geometric shapes and straight lines.
Once you have entered a new combination, the system will ask you to confirm it by re-entering it. Be careful: if you make a mistake in confirming, the process will have to start again. Once installed successfully, the system may suggest setting additional parameters, such as displaying the content of notifications on a locked screen or smart locking when the phone is not locked if it is in a trusted place.
Configure additional screen security parameters
Changing the password itself is only half the battle; you need to configure the associated features correctly to maximize protection. The screen lock menu often features the "Show Notification" option, which allows you to hide the text of messages until you unlock it, which prevents information from leaking even if the phone is in the hands of another person, but the screen is on.
Smart Lock, which allows you to keep your device unlocked under certain conditions, for example, a phone may not require a password when connected to a trusted Bluetooth device (watch or headset) or located in a specific location, but using this feature reduces the overall level of security, since physical access to the phone is not limited at these times.
Also in the settings, you can find the “Block in your pocket” option, which uses a proximity sensor to prevent accidental taps and unlocks when the phone is in your pocket, a feature that is especially useful if your pattern lock consists of a large number of dots and can be accidentally reproduced by the fabric of clothing when you are in close contact with the screen.
Keep in mind the screen timeout, which is the time it takes for the display to go out and lock, and setting too long an interval (e.g., 5 or 10 minutes) increases the risk of unauthorized access if you forget to lock your phone manually, and the optimal value is 30-60 seconds, which balances usability and security.
Mi Account and cloud sync issues
Xiaomi’s tightly integrated ecosystem is integrated with Mi Account, and security changes are often synced to the cloud. When you change your screen lock password on one device, if sync is enabled, the data can be updated on other gadgets you have tied to the same account. This is convenient for managing your device fleet, but requires caution not to lock yourself on all devices at once.
If you forget your Mi Account password, this can be a serious problem, as Find Device and remote lock depend on it. In some regions and firmware versions, when you reset your settings to the factory (Hard Reset), the system will necessarily require you to enter a password from an account that was previously synced with the phone, which is an anti-lock measure to protect against theft.
⚠️ Warning: Never turn off Find Device right after changing your password unless you are sure the new code is secure.This can leave your phone unprotected in the event of loss.
If the system requires verification of identity through Mi Account after changing the password, and you do not remember the data, recovery may take time. It is recommended to always keep up to date the phone number and backup email associated with the account. You can check the status of the anchor in the Settings → Mi Account → Security section.
What to do if you forget your graphic password
The user forgets the pattern lock installed is one of the most common situations. If you make a few incorrect attempts to enter, the system will suggest waiting a certain time (from 30 seconds to several minutes) before the next attempt. This is brute-force protection, and you can't get around it by just waiting if you don't remember the drawing.
One legal way to reset a forgotten password is to use the Forgot password feature, which appears on the lock screen after several failed attempts, which only works if the phone is connected to the Internet (Wi-Fi or mobile network) and if sync with Mi Account or Google Account was previously enabled, the system will redirect you to the authorization page for reset.
If the recovery function is not working or the phone is not connected to the network, the only option is to completely reset the device to the factory settings (Hard Reset), this procedure completely deletes all user data, including photos, contacts and applications, so it should be resorted to only as a last resort.
| Method of recovery | Conditions required | Data security | Difficulty |
|---|---|---|---|
| Through the Mi Account. | Internet, knowledge of the password from the account | Data saved | Low. |
| Google Find My Device with Google | Internet, active Google account | Data deleted | Medium |
| Hard Reset (Recovery) | Physical access to buttons | Complete removal | Tall. |
| Service centre | Device documents | Depends on the method. | Tall. |
Tips for Creating a Reliable pattern lock
The security of your device depends on the complexity of the pattern lock you choose. Many users use simple and predictable shapes such as the letter "L", "Z" or square, which makes it much easier for attackers. Statistics show that more than 50% of all graphical passwords start from the top left corner, so avoid starting from this point.
Use a minimum of 6 points out of 9 available to create a strong password. Try to cross lines, creating a complex trajectory that is difficult to reproduce from memory or see with lateral vision. Avoid symmetrical shapes and do not draw lines through the center of the screen too often, as this is a visually noticeable area.
Password psychology
Rub your smartphone screen regularly, as the oleophobic coating wears off over time and your finger marks become more visible under certain lighting. If you use your phone frequently in public, consider using a matte-effect protective film that hides the traces of touches better than glossy ones.
💡
A complex pattern lock must contain at least 6 points, have no symmetry and do not form recognizable letters or simple geometric shapes.
In conclusion, a graphical password is a convenient trade-off between speed and security, but for storing critical data (cryptocurrency wallets, documents), it is better to use biometrics in conjunction with a complex alphanumeric password that requires periodic input, balancing between convenience and security depending on what information is stored on your device.
