Modern smartphones like the Xiaomi Redmi 9 offer a variety of privacy protection features, including blocking individual apps, a feature known as App Lock that hides the contents of a gallery, instant messengers, or banking programs from prying eyes. However, there are situations where users forget the installed code, pattern lock, or unlock pattern, making it impossible to access important data.
Restoring secure software on MIUI devices requires careful attention, because security works differently than on standard Android. There are several proven methods of bypassing or completely removing protection, ranging from using a Mi Account to radically resetting settings. It is important to understand what kind of way will work in your particular case, so that you do not lose data irretrievably.
In this article, we will discuss all possible solutions for the Redmi 9 model in detail, how to proceed if you remember your password and what to do if you lose access to it, and we will also look at the nuances of security and give recommendations for preventing similar situations in the future.
Principles of application protection in MIUI
The MIUI application protection system is an independent module that runs on top of a standard screen lock, which means that even when you unlock the smartphone itself, you face an additional barrier when you try to open secure programs, which provides a double level of security, but can become a problem when you lose credentials.
The basis of this security system is binding to a Mi Account. When the App Lock function is activated, the system strongly recommends or even requires authorization, this is done so that the owner can restore access through the cloud in case of forgetting a password. Without linking to the account, it is almost impossible to restore access to data inside blocked applications without losing this data.
It is worth noting that application protection does not encrypt the data inside them, but only blocks access to the executable file of the program.
⚠️ Warning: Attempts to hack security software without knowing the password can lead to locking the device itself or data loss.
Unlocking the block through Mi-account
The easiest and most secure way to remove the password from the applications on Xiaomi Redmi 9 is to use the Restore function through the Mi-account. This method only works if you previously linked your account to the application protection function and remember the password from it.
After the third error, the system will offer the option “Forgot your password?” or “Unlock through Mi-account.” By clicking on this button, you will go to the Mi Cloud authorization page. You will need to enter the username and password from your Mi-account. Once successful authorization, the system will suggest setting a new password to protect applications or completely disable protection.
- 🔑 Enter the wrong password three times in a row to make the recovery menu appear.
- 📲 Click on the “Forgot Password” link on the lock screen.
- ☁️ Log in to your Mi-account using current data.
- 🔄 Come up with a new code or turn off the App Lock feature in the settings.
If you don't remember the Mi Account password, you can also restore it through a linked phone number or backup email. However, this process can take some time, especially if you need proof of identity. The key point is that without access to the Mi Account, this recovery method will not work.
☑️ Pre-reconstruction checks
Use of the control question
When you set up application protection on Redmi 9, users often skip the check question installation step, considering it unnecessary. However, if you ask this question and remember the answer, it can be a salvation in a situation with a forgotten password.
When you have an error message, look at the bottom of the screen, and you can have a "Ask for a Check Question" link, and when you click on it, the system will ask you to type in the answer you set earlier, and if the answer is correct, you will be asked to create a new password to unlock the apps.
This method is less reliable than cloud-based binding, as many users forget their answers or do not install them initially, and the number of attempts to enter an answer to a control question can be limited.
⚠️ After several incorrect attempts to enter an answer to a control question, the system may temporarily block the possibility of recovery.
What if the control question is also forgotten?
Reset via security settings (if access is available)
Sometimes users want to remove their password not because they forgot it, but because the security feature got in the way or was installed accidentally. If you have access to the settings menu (meaning you can unlock your phone and log in to settings), it's very easy to turn off application protection. This method doesn't require knowing the old password if you're already inside the system.
To do this, go to Settings → Applications → Application Protection. In some versions of MIUI, the path may look like Settings → Passwords & Security → Application Protection. In the menu that opens, you will see a list of protected programs and a switch at the top of the screen. Just turn off the switch and the system will ask you to enter the current password to confirm the action.
However, if you don't remember the password, this method won't work directly, as the system will require confirmation, but here's the caveat: if you've previously enabled sync with Mi Cloud, you can try to disable protection remotely via the Mi Cloud web interface under Find Device or Security, although the functionality of the web version is often limited.
| Method | Conditions required | Risk of data loss | Difficulty |
|---|---|---|---|
| Mi-account | Account binding, knowledge of password | No. | Low. |
| The checkpoint | Pre-set question | No. | Low. |
| Resetting settings | Access to the recovery menu | High (all data) | Tall. |
| Third-party software | Root rights, ADB | Medium. | Very high. |
Radical methods: Reset to factory settings
If none of the sparing methods worked and Mi Account access is lost, the only remaining option is a full Hard Reset, which is guaranteed to remove all passwords, including application protection, but has a critical disadvantage: it removes all user data from the phone’s internal memory.
Before starting the procedure, make sure you have a backup of important contacts, photos and documents if possible. Turn off Redmi 9 completely to perform the reset. Then press the Up Volume + Power button combination and hold them until the Mi logo appears.
In the Recovery menu, you can navigate with volume buttons and you can choose with power buttons. Select the language, then go to Wipe Data and confirm the action by selecting Wipe All Data. Once you complete the process, select Reboot. The phone will reboot as new, and the application protection will be completely removed along with all other data.
💡
Before you do Hard Reset, try to remember if you used this password somewhere else, like unlocking your screen or Wi-Fi. Often people use the same combinations.
Frequent errors and ways to fix them
When you unlock the Xiaomi Redmi 9, you often encounter common problems. One of the most common mistakes is that you misunderstand the system: many people think that removing the application will take away the protection from it. This is not true: when you re-install the password, it will remain, because it is stored in the system security file.
Another common mistake is trying to use third-party password reset software without Root rights. Most of these apps on Google Play are fraudulent or simply ineffective on modern versions of Android. They may contain malicious code or simply advertise paid services that will not lead to the desired result.
Also worth mentioning is the time desynchronization problem: If the device has a time and date that is lost, Mi servers may not accept a password recovery request, considering the security certificate invalid.
⚠️ Before attempting to recover via account, make sure that the date and time on the smartphone are set correctly and synchronized with the network.
💡
The most reliable way to avoid a forgotten password problem is to use your Mi Account regularly and enable sync immediately after you purchase your phone.
Prevention and safety recommendations
To avoid the problem of blocked applications in the future, it is recommended that you set up your security system right after setting up the new Redmi 9. First of all, make sure that your current Mi Account is listed in the Passwords and Security section.
Use biometrics where possible. Fingerprint or Face ID settings for applications make it much easier to access, and even if you forget the digital code or the pattern lock, biometrics will allow you to log in to the application, and then you can change the password in the settings.
Write complex passwords to a safe place. While this seems obvious, many users are hoping for memory that can fail. Using a password manager or a paper notebook stored in a safe place will save you a lot of nerves at a critical moment. Don't ignore the control questions - come up with an answer that you will definitely not forget, even after a year.
