Modern smartphones store a huge amount of confidential information, from banking applications to personal photos, so protecting the device is no longer an option and becomes a necessity. The pattern lock remains one of the most popular ways to lock the screen due to its visual nature and input speed, but users often face the need to change it, this can be caused by the desire to install a more complex pattern, compromise old code, or simply the habit of using the same passwords on different devices.
In Xiaomiโs ecosystem of Redmi and POCO brands, the process of changing security data has its own characteristics, depending on the version of the MIUI shell or the new HyperOS. Users need to clearly understand the difference between a simple change of the key and a complete reset that is required in the event of loss of access. In this guide, we will discuss in detail the standard methods of changing passwords, and also touch on scenarios when access to the system is lost.
It is important to note that modern versions of the Android operating system closely integrate locking methods with data encryption functions. The graphical password on Xiaomi often serves as the key to decrypting the userdata partition, so changing it is a technically difficult process to reconfigure cryptographic hashes, not just replacing the image in the interface.
Preparing for changes in security data
Before you start modifying your locking settings, make sure you have access to the deviceโs current desktop.If you know the current pattern but want to update it, it will take no more than a minute. However, if you plan to make it harder to protect, you should think ahead with a new pattern that wonโt be obvious to outsiders.
Owners of devices with a shell MIUI are advised to check the status of the binding Mi Account. Mi Account is a critical security element that allows you to unlock the device in the event of a forgotten password through the service Find Device.
There are several scenarios where changing the key becomes mandatory:
- ๐ฑ Youโve noticed that the old pattern is easy to guess from the fingerprints on the screen.
- ๐ You have passed the phone to others and entered a password in their presence.
- ๐ You're moving from digital. PIN-of the pattern lock code or vice versa.
- ๐ก๏ธ Security system requires password change due to suspicious activity.
โ ๏ธ Warning: If you change the pattern lock but forget the new one, unlocking the device without losing data will be extremely difficult. Current Android security protocols don't have backdoors to bypass encryption.
Itโs also worth making sure that the battery is at least 30-40%, and while the process of changing the password is not energy intensive, suddenly turning off the smartphone while reconfiguring the system security files can lead to software errors or a cyclical reboot.
For users who often forget complex combinations, the question of balancing convenience and protection remains relevant. Xiaomi offers the use of biometrics (fingerprint or Face ID) as an alternative, but a backup input method still needs to be installed and reliably remembered.
Step-by-step instructions for changing the pattern lock
The key change process in current Xiaomi firmware versions is standardized, but the path to it may vary slightly depending on the localization. Below is a universal algorithm of actions suitable for most models, including the Redmi Note and the Xiaomi Mi series.
You need to get to the main settings menu first, and to do this, unlock the device in the current way and find the Settings icon (cogs). MIUI often uses the top search bar where you can immediately enter the "Passwords" request, which will greatly speed up the process.
Next, follow the path: Passwords and security โ Device protection (or screen locking). The system will request identity verification by entering the current pattern lock or digital code. This is a mandatory security measure to prevent unauthorized changes in access parameters.
โ๏ธ Password change algorithm
Once you have successfully logged in, you will see a lock type selection menu, and you can switch from pattern lock to pattern lock. PIN-If you select a new pattern, you will be asked to draw it twice to confirm it.
Some firmware versions have a key visibility feature that hides the dot connection lines during input, a useful option to protect against shoulder peeping in public transport, but it requires more accurate hitting points.
The table below shows a comparison of the different locking methods available on Xiaomi devices:
| Method | Level of security | Input speed | Convenience |
|---|---|---|---|
| pattern lock | Medium. | Tall. | High. |
| PIN-code (4-6 figure) | Low/Mediocre | Very high. | Very high. |
| Alpha number password | Maximum | Low. | Low. |
| Fingerprint. | High-pitched | Instant. | Maximum. |
Once a new key is installed, it is recommended to check its performance immediately by locking the screen with the power button and trying to unlock the device in a new way.
Removing password and disabling lock
Fully disabling the screen lock makes the device available immediately after turning on, which is convenient for home tablets or test devices, but is categorically not recommended for major smartphones.
To remove protection, go to Passwords and Security โ Device Protection โ Lock screen. From the list of methods, select No or Swipe (depending on the version of MIUI), the system will warn you that all saved passwords will be deleted and biometric data (fingerprints, face) will cease to work.
๐ก
Before you completely disable the screen lock, remove all saved bank cards from Mi Pay and Google Pay, as they may stop working or become vulnerable.
It is important to understand that when you turn off the lock screen, all stored fingerprints and facial recognition data are automatically deleted, so that no one can add their biometrics to the unlocked phone when they have physical access.
If the "No" option is inactive or not, this may mean that the device has activated corporate security policies (for example, when installing work email profiles) or has enabled Find Device mode with strict requirements, in which case you must first delete work profiles or turn off device search.
Some users try to disable passwords through secure boot mode, but on modern versions of Android, this will not remove the password if it is already installed as the main method of protection. The only way to remove a forgotten password without entering it is a complete reset, which will be discussed below.
What to do if you forget your graphic password
The situation of a user forgetting the installed pattern lock is one of the most stressful.Unfortunately, unlike older versions of Android, modern systems do not allow you to simply reset your password through your Google account after 5 failed attempts without losing data.
If you forget the key, you have two main ways to solve the problem: the first and most humane is to use Xiaomi Find Device, which requires that the phone has the Internet on, geolocation enabled and activate the Mi Account. You can send a command to remotely unlock through the web interface.
The second way, which is 90% of the time, is to completely reset your device to the factory settings (Hard Reset), which completely cleans the internal memory of the smartphone, removing photos, contacts and applications, but returns access to the system.
To perform a reset via the Recovery menu:
- ๐ต Turn off the smartphone completely.
- ๐ Press the Volume Up button and the Power button at the same time.
- ๐ฅ๏ธ Wait for the Mi logo or the Recovery menu to appear.
- ๐ฌ๐ง Select English and press Wipe Data โ Wipe All Data.
โ ๏ธ Warning: After resetting and rebooting, the phone will require you to enter a password from a Google account or Mi Account that was synced earlier (FRP Lock, which cannot be bypassed by simple methods.
Why canโt you just reset your password through ADB?
There are myths that you can bypass locking through Fastboot mode by connecting your phone to a PC. However, Fastboot mode on Xiaomi is designed for flashing, and standard firmware will not remove FRP (Factory Reset Protection) lock, but only update the system, maintaining the authorization requirement.
Biometrics as an Alternative
To minimize the need for frequent pattern lock input, security experts recommend setting up biometric authentication. Xiaomi smartphones are equipped with both fingerprint scanners (in-screen or on-button) and facial recognition modules.
To set up, go to Passwords and Security โ Unlock by fingerprint. The system will suggest several times to apply your finger to the scanner to create a digital cast. It is recommended to add several fingerprints (for example, the thumb of the right and left hand), as this increases the usability in different situations.
Facial recognition in MIUI It works fast enough, but it has a nuance: on many models it uses the same. 2D-A camera that is less safe than a camera 3D-scan. Face. ID Xiaomi is not recommended for confirming payments in banking applications, but is great for quickly unlocking the desktop.
Biometrics also offers a feature called โUnlock in your pocketโ or โHigh sensitivityโ, which can be useful when using security glasses. Remember that biometrics is just a convenient way to enter a preset digital or graphical password that you still need to enter periodically (usually after a reboot).
Frequent problems and their solution
Users may experience a situation where the touch screen is not responding correctly and it becomes impossible to draw the correct key, often due to contamination of the screen, moisture or poor-quality protective glass that violates the (capacitive) properties of the display.
If the screen is "glutchy," try to wipe it with a soft cloth and remove a case that can press on the edge. USB-mouse-over OTG. This will allow you to accurately click on the points or enter PIN-code if the system allows you to switch to digital input after several failed attempts.
Another common problem is the message "Too many attempts to enter" in which the system blocks the ability to enter for a certain time (from 30 seconds to 30 minutes). Xiaomi does not allow to speed up this process, and the only solution is (patience).
๐ก
Using an OTG adapter with a mouse is the only reliable way to unlock the phone if the touchscreen is damaged or does not respond to touch.
Also worth mentioning is the problem of time desynchronization: If the device has run out of battery or crashed and time has gone wrong on a date from the past, security certificates may not work, which will lead to an error when entering the correct password or the inability to unlock through the account. Checking the time relevance in the settings menu can help in rare cases.
