How to change your password to Xiaomi Redmi 9T: the full guide

With smartphones storing a huge amount of sensitive information, from banking apps to personal correspondence, access protection is becoming a priority. Xiaomi Redmi 9T, despite its availability, features a powerful MIUI shell that offers flexible security settings that require competent management. Many users buy a device with their hands or simply haven’t changed standard combinations for a long time, which creates potential vulnerabilities in the system of personal data protection.

Changing the access code doesn’t require any deep technical knowledge or connection to a computer, all the necessary tools are built into the operating system interface. Correctly configuring the screen lock settings is the first and most important step in securing the digital perimeter of your gadget. In this article, we will discuss in detail the algorithm for replacing a forgotten or old password, and also consider additional authentication methods.

Preparing for changes in security settings

Before you start modifying system settings, you need to make sure that the device is stable and manageable. If you plan to change your password because you forgot the current one, the situation requires a separate approach using a Mi Account or reset, but if you have access to the settings menu, the procedure takes only a couple of minutes. It is important that the battery is at least 20-30%, since a sudden power outage at the time of writing new data to the system partition can lead to a software failure.

It is recommended to remember or write the current access code in advance, as the Android system and the MIUI shell will necessarily require its confirmation before making any changes to the security profile. This is a basic security mechanism that prevents unauthorized access by an attacker who received short-term physical access to the unlocked phone.

It is also worth checking whether the device has activated the Xiaomi Mi Account, as in some scenarios to restore access or when you turn on the “Find device” function, it may be the only way to regain control of the gadget. SIM-Cards are also desirable for verification SMS-codes, if two-factor authorization is enabled.

Step-by-step instructions for changing the lock password

The settings interface in Xiaomi Redmi 9T is structured logically, but due to localization and firmware versions, the names of items may differ slightly. First, unlock the screen and go to the main app menu, finding the icon with the gear that indicates the Settings section. Next, you need to scroll down to the Passwords and Security block, which is the central access control node.

Within this menu, select Device Protection or Screen Lock, which displays the current unlock method. PIN-A code, graphic or password is a critical step in verifying the identity of the owner, and once successfully entered, a list of available methods will be opened where you can choose the desired type of new protection, such as replacing a simple 4-digit pin with a complex alphanumeric password.

When you enter a new combination, be careful not to use easily selected sequences like “1234” or dates of birth that are easy to calculate. Once you enter a new combination, the system will ask you to confirm it by re-entering it to exclude an accidental error in the type. If everything goes well, the new password will be activated instantly, and the next screen turn on will require a new combination.

Set up biometric unlocking

In addition to traditional input methods, the Xiaomi Redmi 9T features a fingerprint scanner built into the side button, which greatly speeds up access to the device. Biometrics does not replace a fully digital password, but serves as a convenient and quick way to log in in in everyday use. To set up, you need to go back to the Passwords and Security menu and select the Unlock by fingerprint section.

The scanning process requires adding fingerprints alternately, pressing your finger against the sensor and slightly changing the angle of inclination to capture all the edges of the pad. The system will create a digital cast that will be stored in a secure part of the processor, making the theft of biometric data almost impossible. It is recommended to add fingerprints of both thumbs, since the phone can be in the hand in different positions.

Besides, the shell MIUI It allows for face unlocking, although this method is considered less safe than fingerprinting due to the use of a conventional front camera without the need for a face unlock. 3D-However, for quick access to a gallery or browser, this is a reasonable option that can be activated at the next menu item on the security settings.

Add fingerprints in good lighting and dry hands – this will improve the accuracy of recognition in the future.

Table of comparison of protection methods

The best security method depends on the balance between convenience and the level of security required, so it is important to understand the differences between the options available. Below is a comparative description of the main locking methods available on the Redmi 9T, which will help determine priorities.

As you can see from the table, the alphabetic password provides the highest degree of data protection, but requires more time to enter in emergency situations. Biometric data combines high security and speed, but always have to be duplicated with a reliable digital code in case of sensor failure.

Elimination and restoration of access

Users often experience a situation where the device stops accepting the usual combination of numbers, which can be caused by a touchscreen failure or software error. If you are sure that you are entering the correct code, but the phone responds with a vibration or error message, try restarting the device and entering the data again. In some cases, cleaning the Security service cache through the recovery menu helps, but this requires access to Recovery Mode.

A more serious problem is the complete loss of memory about the current password, which makes the device unavailable for use. In this case, the only official way to regain control is to perform a full Hard Reset, which will destroy all user data on the internal drive. + Food before the appearance of the Mi logo.

Once you log into the Recovery menu with volume buttons, select the language (English), then go to Wipe Data and confirm the action. The device will clear and return to factory condition, after which you can set a new password when you first set up.

Additional security parameters of the device

The MIUI shell offers a number of advanced features that enhance standard screen locking and make it almost impossible for outsiders to hack the device.One such feature is "Pocket Mode," which locks touch buttons when the phone is in the bag, preventing accidental taps and setting a "pocket" password.

Also worth paying attention to the feature “Show notification on locked screen”, which is better to turn off for banking applications and instant messengers to hide the content of messages from prying eyes. In the section “Privacy”, you can configure the concealment of the contents of notifications until the moment of unlocking with biometrics or code.

Another important element is the automatic lock setting, which determines how long the screen will go out and require a password to be entered, and it is recommended to set the minimum possible time, such as 15 or 30 seconds, to minimize the window of opportunity for unauthorized access.

Comprehensive protection is achieved not only by a complex password, but also by competently setting up the screen timeout and hiding confidential notifications.
