How to set a password for the application on Xiaomi Redmi 8T

Xiaomi’s smartphones, including the popular Redmi 8T, provide users with powerful built-in privacy protection tools. Unlike many other manufacturers, you don’t have to install third-party software from the Google Play Store. MIUI already has a ready-made feature that allows you to hide information from prying eyes in just a few touches, especially when children use the phone or when you need to give the device to a friend for a short time to call.

Set-up protection on individual programs is not just a “just in case” feature, but a necessary measure of digital hygiene. The privacy of correspondence, banking transactions and personal photos depends on how well you configure access to them. In this article, we will discuss in detail how to activate the lock, what types of authentication are available, and how to use additional security features such as hidden space.

The setup process is intuitive, but it has its own nuances, which are specific to the MIUI shell. We'll look at all the steps in sequence so you don't have any questions. You'll learn not only to set a password, but also to hide the application icons themselves, making them invisible to the casual eye. This is a comprehensive approach to the security of your Android device.

Preparing a security system before setting limits

Before you go directly to locking specific programs, you need to make sure that the system has a basic method of unlocking the screen. If you use only a pattern lock for the screen, the system will suggest using it or require you to set a digital key. PIN-code.

It's important to understand the difference between unlocking a screen and protecting individual files: One opens up access to the entire device, the other creates an additional barrier inside the system. For the Redmi 8T, the best solution is to use a combination of methods: a fingerprint for speed and a digital code for reliability, which will provide a balance between usability and cybersecurity.

It’s also worth checking if your version of MIUI has been updated to the latest available, and old builds may have had vulnerabilities that allowed you to bypass security through certain settings menus. Go to Settings → About your phone and check for updates. Up-to-date software ensures that encryption mechanisms work correctly.

⚠️ Note: If you forget the password from blocking applications, it may not be possible to restore access without resetting data.

Don't ignore the system's suggestion to create a backup password or link an account. This is not a bureaucratic procedure, but the only way to return access to sensitive data in the case of forgotten code. In Redmi 8T, this mechanism works stably, but requires pre-setting.

Step-by-step instruction for activating application protection

The process of turning protection on MIUI is standardized and takes no more than a minute. You don't have to search for hidden menus or enter engineering codes. All the necessary tools are in the standard Security app, which is pre-installed on every Xiaomi device, which is a centralized hub for managing performance and protection.

To start, open the Security app (green shield icon). In the list of features, look for Application Protection. If you don't see it on the main menu screen, scroll down or click three dots in the corner for a full list.

Once you have entered your password, you will be asked to choose which programs require protection, you can tick the boxes against messengers, gallery or bank clients, lock the device immediately after you have selected it, and when you try to open the selected application, the system will request proof of identity.

Special attention should be paid to password settings: you can choose from the security menu whether you want to use a pattern lock, a digital code or a mixed password. For Redmi 8T with its fingerprint scanner on the back, it is most convenient to use biometrics in conjunction with a digital code in case your finger is wet or wearing a glove.

Use of biometrics and additional parameters

Modern smartphones, including the Redmi 8T, allow you to use biometrics to confirm actions. In the context of application protection, this means that you don't have to enter long code every time. Just put your finger on the scanner on the back and access is allowed. This greatly speeds up the work with the device.

But biometrics has its limitations, and fingerprint scanners may not work if your hands are wet, dirty or damaged, which is why having an alternative digital password is a requirement of the system, and you can't stop creating code even if you plan to use only a fingerprint.

The application security settings also have a "Unlock by fingerprint" option, which makes sure it's activated, which allows you to open secure programs as soon as you unlock the phone itself if the fingerprint matches, and if you give the phone to another person, the system will request the password again when you first run the secure application.

💡

Use different fingers to unlock the screen and to confirm payments if you are afraid of accidental authorization in the app immediately after unlocking the phone.

Another important parameter is the time it takes to recheck your password, so you can set the system to request the code every time you open the app, or only after a certain period of downtime, and this is set up in the additional menu of security settings.

Application Hidden Function (Hidden Space)

There is a feature in Xiaomi that goes beyond just locking it down: Hidden Space (or simply Hide Apps) when this option is activated for a particular program, its icon disappears completely from the desktop and from the menu of all applications, and it can only be found through a special entrance to hidden space.

To activate this feature, go to the application protection settings and find the Hide Apps switch, and when you turn on each blocked application, you'll see an additional option next to it, activate it for those programs you want to make invisible, which creates a double level of privacy.

The gesture used to enter hidden spaces is usually swiping two fingers up and down on a desktop or entering a special code into a search box, and you can adjust the exact login method in terms of settings, so you can keep your personal photos or correspondence completely hidden from prying eyes.

This can be both a plus (no one will see a pop-up message) and a minus (you can miss an important call).

Comparison of protection methods in MIUI

Redmi 8T users have multiple layers of protection, and it's important to understand the differences: Just locking the screen only protects the phone's entry; protecting apps adds a barrier inside the system; hiding space takes apps out of sight; combining these techniques maximizes the effect.

The table below compares the main characteristics of different access restriction methods so that you can choose the best strategy for your needs.

As you can see from the table, Second Space is the most radical method: it creates a completely separate desktop with its own apps and settings, as if you have two different phones, switching between the main and second spaces through a user change or a special password.

For most Redmi 8T users, the combination of App Protection and Hidden Space is enough, and it doesn’t overload the system and provides strong protection for personal data from children, friends or colleagues who have taken your phone in their hands.

Addressing problems and restoring access

Sometimes users are faced with a situation where the password is forgotten and access to important data is necessary. MIUI has a recovery system through the Mi Account. If you linked an account when you set up security, you can reset the password through it, you will need to answer a security question or get the code to the mail.

If the account is not tied, the situation becomes complicated, because for security reasons, the system does not allow you to simply bypass the security, the only way out is to completely reset the phone settings (Hard Reset), which will lead to the deletion of all data, so it is critical not to ignore the initial stages of security settings.

It’s also worth noting that after a MIUI update, your security settings may get lost or need to be re-confirmed, which is normal behavior associated with updating Android security components. Just re-confirm your data when you first start after the update.

⚠️ Warning: Resetting via Recovery Mode will delete all data from internal memory.

If you sell or give away a phone, be sure to do a full reset. Even if you delete apps, the data residue can be saved.The Clear All Data feature in the settings ensures that the new owner will not be able to access your information even using special recovery programs.
