Modern smartphones Xiaomi, Redmi and POCO offer users many ways to protect personal data, among which the most popular is fingerprint scanning. This feature provides instant access to the system, but in some situations it can be inconvenienced or cause concerns about privacy, for example, if the sensor is not working correctly, unlocking occurs in your pocket or you simply prefer to use a digital code.
The process of deactivating biometric protection in the MIUI and HyperOS shells is not always obvious to beginners, since security settings are scattered across different menus. In this article, we will detail how to completely disable unlocking with your finger, removing stored biometric data, and consider alternative methods for protecting your device.
It is worth noting that simply ignoring the scanner does not disable the function – fingerprint data continues to be stored in a secure memory area. To completely abandon the technology, you need to perform a sequence of actions to remove profiles, which ensures that even with physical access to the phone on, no one can unlock it with someone else’s finger.
Why turn off biometric unlocking on your smartphone
The decision to abandon fingerprinting can be driven by a variety of reasons, both for convenience and security, where some users are faced with a situation where the sensor responds to random touches, which leads to unintentional turn on of the screen and battery consumption, in which cases, completely turning off the function becomes the only effective solution.
There is also the aspect of forced unlocking: In some jurisdictions or specific situations, law enforcement may require a device to be unlocked with biometrics, whereas a digital password or pin code is protected by law more strongly, disabling biometrics shifts protection to a level of knowledge rather than physical characteristics.
- 🔒 Increasing the level of legal data protection in the inspection of the device.
- 🔋 Removing false sensor alerts in your pocket or bag.
- 👆 Solving problems with the scanner incorrect operation with wet hands.
- 🧹 Complete removal of biometric patterns from system memory.
In addition, users with skin conditions or features of the elevation of the fingers may have difficulty constantly reconfiguring the sensor, in such cases, switching to a classic pattern lock or a complex password is a more reliable and less annoying use case of a smartphone.
Preparing for changes in security settings
Before you make changes to the security configuration, you need to make sure you have an alternative way to log in. PIN-If you forget the code, password or pattern lock every time you unlock it, you can lose access to the data forever.
Check the current password beforehand, go to the settings menu and make sure you remember a combination of numbers or a pattern, which is a critical step, because the process of deleting biometrics often requires confirmation of actions with this code.
☑️ Preparation for biometric removal
Also, you should consider that disabling the fingerprint scanner will affect the operation of some applications: Banking programs, messengers like Telegram or WhatsApp, and password managers often use system biometrics to quickly log in. Once you turn off the feature, you will have to enter passwords manually in each application.
⚠️ Attention: Deleting fingerprint data is irreversible. If you decide to use the scanner again, you will have to register your fingers again, undergoing a scanning procedure from scratch.
Step-by-step: Removing fingerprints in MIUI and HyperOS
The process of disabling finger unlock on Xiaomi devices is not to find the switch switch, but to remove saved profiles. As long as the system stores at least one fingerprint, the function is considered active. The interface may vary slightly depending on the version of the shell, but the logic of actions remains the same.
To start, open the main settings menu for your smartphone. Find the security and account section. Newer versions of HyperOS may call it Passwords and Security, whereas older versions of MIUI often use the name "Advanced" or simply "Fingerprints and Unlock."
Settings → Passwords and security → FingerprintsOnce logged in, you will need to verify your identity with your current lock password, a standard security measure that prevents the removal of biometrics by unauthorized persons who have access to the phone on.
In the list that opens, you will see profiles marked as "Fingerprint 1", "Fingerprint 2" and so on. To completely disable the function, you must delete each of them. Click on the appropriate profile and select the deletion option, often indicated by the basket icon or the "Delete" button.
What to do if the menu does not open?
Configuring alternative screen protection methods
Once the biometric data is deleted, the system will automatically switch to the main locking method, but you can change it to a more convenient or secure option. The pattern lock is considered less reliable than the long alphanumeric password, but more convenient for frequent input.
There are several options available in the screen lock settings menu: Swipe (swipe), Pattern (picture), PIN (digital code), Password (password) and None (no protection). For maximum security, it is recommended to choose a complex password containing letters and numbers, although this can slow down the unlock process.
| Protection method | Level of security | Input speed | Convenience |
|---|---|---|---|
| Fingerprint. | High-pitched | Instantly. | Very high. |
| A complex password | Maximum | Low. | Low. |
| pattern lock | Medium. | Medium | High. |
| PIN-code (4-6 figure) | Medium/High | Tall. | High. |
Remember that choosing the No or Swipe method leaves your phone completely open to anyone who picks it up, which is only acceptable if the device is used as a media player or navigator without storing personal information.
Control application access after disabling the scanner
Many Xiaomi users use the Application Protection feature, which allows you to put an additional password or fingerprint on the launch of specific programs. After disabling global biometric unlock, these settings will also require attention.
When you try to open a secure application (such as a Gallery or a Banking application), the system will no longer prompt you to attach a finger, instead, immediately a field will appear to enter a password or a pattern lock installed to protect the applications, which can be the same code as the one to unlock the screen, or a separate one.
To change your settings, go to the security section and find "Application Protection," where you can add new programs to the list of protected programs or exclude them from the list, and here you can configure the unlock method: if you delete the fingerprint from the main settings, it will also stop working here.
- 📱 Check the settings of the entrance to the banking applications (Sber, Tinkoff, etc.).
- 💬 Update the ways of authorization in messengers Telegram and WhatsApp.
- 🔐 Reconfigure password managers if they used biometrics.
- 🖼️ Check the hidden folder in the Gallery if it was protected.
⚠️ Note: Some banking applications may require re-associating the device or changing the authorization method within the application itself after disabling the system fingerprint scanner.
Frequent problems and ways to solve them
During the setup process, users may encounter a situation where the fingerprint deletion button is inactive or the system issues an error, often due to the fact that the advanced unlock feature is enabled, which allows you to open the phone with your finger even if the screen is turned off, or with a conflict of access rights.
Sometimes the problem is that the shell itself is software-based, and if you just reboot the device, if the system continues to require a fingerprint instead of a password when you log in, try clearing the Settings or Security app cache through the application management menu.
💡
If the sensor stopped responding after the system update, try to clean the scan area with an alcohol wipe and recreate the fingerprint profile before completely removing it.
On devices with underscreen scanners, there is sometimes a bug where deleting the profile does not reset the sensitivity settings, in which case resetting all settings to factory settings can help, but this is an extreme measure. Usually, re-registration of the finger and subsequent deletion solves the problem of "sticking" the function.
💡
Complete disabling of unlocking with your finger is achieved only by removing all stored biometric profiles in the security menu, simply turning off the switch is not enough for this.
