How to turn off the lock screen on Xiaomi Redmi Note 9

Xiaomi’s Redmi Note 9 series offers users a wide range of functionality and strong data protection. However, sometimes it is necessary to remove security barriers, for example, if the device is used by a child or used exclusively on a home Wi-Fi network to control a smart home. The process of deactivating the screen protection in the MIUI shell has its own features, which are important to consider so as not to lose access to the gadget.

In this guide, we will take a look at all the steps of removing a password, pattern lock or fingerprint. You will learn about the system limitations that can prevent a simple shutdown and how to circumvent them. Understanding the security principles of Android will help you to properly customize your device to your needs without risking personal data.

It's worth noting that removing the lock completely makes the phone vulnerable to unauthorized people. If you lose the device, anyone who finds it will have full access to your photos, contacts and accounts. So before making changes, weigh the risks and make sure the device is in a safe place.

Preparing the device for changes in settings

Before you make security changes, you need to make sure you have full control of the device, and first of all, you need to know your current password or have access to biometrics, because the system will ask for confirmation before you turn off the protection, and without entering the current code, you can not change the security settings.

It’s also important to check whether Google’s Find Device or Xiaomi Cloud is activated, and if these services are active, the system may require you to enter a password from your account even after you disable the local pin code, a standard theft protection measure that manufacturers implement.

⚠️ Note: If you forget your Google account password after resetting your lock settings, you may encounter an activation screen. FRP, Which cannot be avoided without account information.

It is recommended to back up important data in advance. Although the process of disabling the password does not usually result in file loss, an accidental failure or an error can lead to unintended consequences.

Standard way to disable password through settings

The basic deaktivatsii screen protection method is available through the standard operating system settings menu, which is suitable for most users who simply want to eliminate the need to enter code every time the display is turned on.

To start, open the main menu and find the Settings section, and you're interested in what might be called Passwords and Security or just Security in different versions of the firmware, and within that section, you'll select the Lock screen option, and the system will ask you to enter the current security code immediately.

Once you have successfully authorized, you will be asked to choose a new type of lock, so to remove the protection completely, you need to scroll down to the bottom and select No or Disable. In some versions of MIUI, this item can be hidden if certain security features are activated.

• 🔓 Open the Settings menu on your Redmi Note 9.
• 🔐 Go to the Passwords and Security section → Screen locking.
• ✅ Enter your current password, pattern lock, or use your fingerprint.
• ❌ Select the option No in the list of ways to block.

Once you select the option, the system will issue a warning that all stored face or fingerprint unlock data will be deleted, which is normal because the biometrics are tied to the primary protection method, and confirm the action, and the lock screen will disappear.

Deletion of biometric data and associated accounts

Often, users are faced with a situation where the system does not allow you to choose the “No” option to lock the screen. This is because the device has stored data to unlock the face or fingerprint. Android does not allow you to have biometrics without a basic digital or graphical password.

To solve this problem, you must first delete all stored biometric profiles. Go to the Passwords and Security menu and find the Unlock by fingerprint or Unlock by face section, and delete previously added data inside each section.

Also check the Security → Device Administrators section, if third-party applications that require a password are activated (such as corporate email clients or antiviruses), they can block the ability to disable protection.

Once all biometric profiles have been cleared, go back to the lock type selection menu, and now the full shutdown option should be available, and if the system continues to require a new password, check if the device encryption feature, which often requires an unlock key, is enabled.

The problem with encryption and how to get around it

Modern Xiaomi smartphones, including the Redmi Note 9, use data encryption by default, which means that all information on the drive is protected by a key that is generated based on your password or pattern lock. Without this key, the operating system cannot properly start and decrypt user data.

That's why when you try to disable your password, you might see a message that some features require protection, and in those cases, you can't just delete the code without losing data or resetting the settings, and encryption is a fundamental part of Android security.

⚠️ Warning: Attempts to bypass encryption through third-party utilities can result in complete data loss and inability to boot the system (bootloop).

The only safe way to remove the password when you're actively encrypting is to reset the device completely to factory settings, and this action will remove the encryption along with all the data, and when you first set up the new state, you won't have to set the password at all, but this is a last resort.

Resetting settings as a radical method

If standard methods don’t work or you forget your password, the only way out is to reset through Recovery Mode.This method completely clears the internal memory of the smartphone, returning it to the “out of the box” state. After this procedure, the Redmi Note 9 will be as new, without any locks.

To enter recovery mode, you need to turn off your smartphone. Then press the volume button and the power button at the same time. Hold them until the Mi logo appears, then release the power, continuing to keep the volume. You will be taken to the main Recovery menu.

In the Recovery menu, you can control volume buttons (up/down) and confirmation with the power button. You need to select a language (if available immediately) or immediately go to Wipe Data. Then select Wipe All Data and confirm the action.

Once you have cleaned, select Reboot → Reboot to System. The phone will reboot and the initial setup will begin. During the system setup phase, you may be asked to enter a password from a Google account that was previously synced to the device (FRP protection). Once successfully logged in, you will be able to use the phone without setting a new password to the lock screen.

Alternatives: Smart home and guest mode

Sometimes you don't need to shut down completely, you just need to have a temporary absence of obstacles to access, so you can use Guest Mode or set up smart scenarios, for example, if the phone is used as a smart home control panel on the wall, you can set up automatic unlock on a specific Wi-Fi network.

You can use applications like Tasker or built-in MIUI tools to implement automation scenarios. However, it is worth remembering that there is no full-fledged “aut-unlock over Wi-Fi” feature in Xiaomi’s stock firmware, and additional rights or complex settings are required.

Guest mode allows you to create a clean space without your personal apps and data, but logging in can still require confirmation.This is a good option if you give the phone to your child for games, but do not want to completely remove protection from the main profile.

💡

Use the “Second Space” feature to create a separate profile without a password if you need to transfer your phone to other people often without showing your personal details.

Possible errors and ways to eliminate them

Users may encounter various system messages during the setup process. Often, an error occurs when the "Disable" button is inactive or disappears after selection. This may be due to the device's device search activated or security certificates from third-party applications installed.

Check the list of trusted agents in the developer settings (if enabled) or in the security section. SIM-The card does not require PIN input every time you reboot, although this does not directly affect the screen lock, but can create confusion.

If nothing helps and the system cycles back to the password creation screen, it may be that system files are damaged or the firmware has errors. In this case, it is recommended to flash the device through the computer using the Mi Flash Tool utility, but this requires certain technical skills.

💡

Complete deletion of the password is possible only in the absence of active biometric profiles and third-party device administrators requiring data protection.
