The situation when the owner of a Xiaomi or Redmi smartphone suddenly forgets the previously installed pin code or pattern lock from hidden applications is quite common.The MIUI security system and the new HyperOS are designed to protect personal data from prying eyes as much as possible, but this strictness becomes a problem for the user. Unlike unlocking the screen, where there is a “Forgot password” feature, logging into a hidden partition often seems to be a dead end without special knowledge.
Fortunately, there are several recovery scenarios that have been developed, but the availability and activation of these scenarios depends on the operating system version and the account presets, and data security is a boundary between convenience and reliable protection, and if you haven't tied a Mi Account or set up control questions, the process can be complicated, but there are still options.
In this guide, we will look at all possible ways to restore access to your photos, notes and hidden applications. We will look at both standard methods through cloud services and technical workarounds that will help you regain control of your device. It is important to understand that some methods can lead to data loss inside a secure container, so you should be careful when choosing a strategy.
⚠️ Warning: Brute-force attempts to match passwords can lead to temporary locking of the input function or full encryption of data if theft protection is enabled. Do not enter incorrect codes more than 10 times in a row.
Staff reset via tied Mi Account
The system provides the easiest and safest way to restore access to hidden applications if you have previously linked your account. In most cases, after several failed attempts to enter a password, the hidden partition screen will display the words “Forgot your password” or the corresponding icon on the hidden partition lock screen, clicking on this element redirects the user to the Xiaomi Account authorization page.
To successfully recover, you will need to enter the username and password from your Mi Account that was active at the time of the security installation, the system checks the data with the server and, in case of a match, suggests entering a new pattern lock or digital code, which works on modern shells MIUI 12, 13, 14 and HyperOS, because it is tied to cloud-based synchronization of credentials.
If no automatic offer appears, try to enter the wrong password 5 times in a row, then the system must force the recovery through the account, this is the standard verification procedure, designed to ensure that the device is owned by the authorized user, and not by the third party who found it.
💡
If you have recently changed your Mi Account password, wait about 15-30 minutes before trying to recover, as servers need time to sync the new security data.
However, if you don't remember the data from the account or have not linked it at all, this method becomes unavailable, in which case the security system performs its function - it blocks access, and you can not log in without a back door, which is why experts always recommend keeping data from the main account in memory.
Use of service code to reset protection
There is a hidden system mechanism in MIUI shells that allows you to reset your application protection password through a special service code, which works at the system level and often does not require an Internet connection, making it a universal solution for many users, but its availability depends on the specific version of the firmware and the regional location of the device.
To activate the reset, you need to open the standard Phone app and enter a special combination of characters. The most common code to reset the application protection password is ##6484## or variations like ##64663## that open the engineering menu. However, for direct password resets, you often use the code ##6484## (CIT) where you need to look for security-related tests, but the more direct method is to use the reset code if it is activated in your build.
More effective and specific to protect applications is the code ##6485##, which shows battery information but does not reset password. Real reset is often done through code ##64663## -> search for the "Security Center" test or through direct entry of the unlock code if it was set by developers for your region. In recent versions of MIUI, the direct code can be blocked, then only the following method will help.
Does the code work on global firmware?
It is worth noting that the use of engineering codes requires caution. Incorrectly changing the parameters in the engineering menu can lead to incorrect operation of communication modules or sensors. If you are not sure about your actions, it is better to limit yourself to those items that relate to resetting security passwords.
Safe Mode Method for Disabling Third-Party Blockers
If standard methods don't work and you don't remember the password, you can try Safe Mode, which loads the Android operating system with third-party services disabled and sometimes allows you to bypass locks imposed by system applications if their cache is cleared. However, on modern versions of MIUI, protection is built deep into the Security Center system section, so this method does not always work, but it is worth trying.
To enter Safe Mode, you need to press the power button and then press the "Stop" icon on the screen for a long time until the suggestion to go to Safe Mode appears. After the reboot, the corner of the screen will say "Safe Mode." In this state, some system restrictions can be relaxed, which will allow you to go to settings and clear the data of the "Security" application.
The path to data cleanup is usually: Settings → Applications → All applications → Security → Memory → Clean. It is important to clear the cache and data of this system component. After this procedure and reboot to normal mode, the password can be reset to factory or deleted altogether.
☑️ Safe mode operations
It should be understood that cleaning the data of the system application "Security" can lead to resetting other settings, such as permissions for applications or settings of antivirus, which is a compromise that must be made to restore access to personal files.
Reset via control questions and email
When you first set up your application protection, it often suggests you set a security question or link a backup email address, and if you neglected to do that, you can skip that section, but for many users, that's the mechanism that's going to be a lifesaver, and unlike Mi accounts, it's locally or through standard email protocols.
After several failed attempts to enter, click on the link "Forgot the password." If you set a control question, the system will prompt you to answer it. PIN-It's a classic recovery mechanism that works even without Internet access, if the data is stored locally in encrypted form.
The table below shows the main differences between recovery methods so you can choose the right one:
| Method | We need the Internet. | I need a Mi Account. | Risk of data loss |
|---|---|---|---|
| Mi Account. | Yes. | Yes. | No. |
| The checkpoint | No. | No. | No. |
| Service code | No. | No. | Medium. |
| Data Clearance (Safe Mode) | No. | No. | High (settings) |
If neither of these options works because you don't remember the answers to the questions or you haven't tied your mail, it gets complicated, and then the system sees you as a potential intruder with no access rights, and the only way out is to completely reset the device, which we'll talk about later.
Radical measures: complete resetting of the device
When all methods are exhausted and access to important data inside the hidden container is lost, the last option is Hard Reset, which is a complete cleaning of the smartphone to a factory state. It is important to understand that this method will remove all user data from the device, including photos, contacts and applications, so it is only a last resort.
To perform the reset, you need to turn off the smartphone, then press the combination of power buttons and volume increase (on most Xiaomi and Redmi models). In the Recovery menu that appears, select the Wipe Data button and confirm the action with the power button. After the process, the phone will reboot as new.
⚠️ Warning: Once reset, the device will request a password from a Google account or Mi Account that was previously synced (FRP). Make sure you remember this data, otherwise the phone will become a brick".
This method is guaranteed to remove any software locks, including forgotten passwords from applications, as the entire partition with user data is deleted. However, files from a hidden album or hidden applications that were not synced to the cloud will be lost irretrievably.
💡
Hard Reset is the only 100% way to unlock your phone if you forget all your passwords, but it results in a complete loss of data on your internal drive.
Prevention: How to avoid losing access in the future
To prevent a forgotten password from happening again, you need to set up your security system right after you buy or reset, first of all, make sure that the application protection settings include the option “Use fingerprint” or “Use face unlock.” Biometrics greatly simplifies access and reduces the risk of forgetting the digital code.
It's also critical to check your Mi Account's binding status regularly, go to the security settings, click on the gear and make sure the account is displayed and is "Active." This is your main emergency recovery key. Don't ignore the suggestion to back up your security settings.
- 🔒 Be sure to link Mi Account in the "Application Protection" section".
- 📸 Turn on sync of the hidden album with Mi Cloud so that photos do not disappear during reset.
- 🔢 Write down the password you have set in a safe place (notebook, password manager) rather than storing it only in memory.
- 👆 Set up biometric unlocking as the primary method of entry.
Compliance with these simple rules will allow you to enjoy the privacy features of Xiaomi without fear of losing access to your data. Remember that security is a balance between the complexity of a password and the ability to restore it.
