Xiaomi and Redmi smartphone owners often use the “Second Space” feature to separate work and personal data, a virtual clone of your device that works as a separate phone inside your phone, but like any security system, it is sometimes lost. Forgotten pattern lock or PIN-Code can block access to important photos, documents and correspondence.
Changing a password isn't just about changing numbers, it's a process that requires understanding the logic behind a MIUI shell or HyperOS. Unlike unlocking the main screen, it's more stringent security protocols, because the second space is often used to store sensitive information. If you just want to change the access code knowing the old one, it takes a couple of minutes. If access is lost, more complex manipulations are required.
In this article, we will look at all possible scenarios, from a regular change of code through settings to a forced reset if you forget the combination. We will touch on the nuances of working with a Mi Account, as it is often the key to recovery.
Regular change of password through settings
The easiest and safest way to change the access code is to use the regular menu if you have current access to the second space, which does not require deletion of data and works consistently on all modern versions of the firmware. First, you need to switch to the second space using your current password or fingerprint.
Once you log in to the second space interface, the action algorithm is almost identical to the main screen setting. → Passwords and security → Privacy protection. This is where the encryption keys and access parameters are stored. The system can request proof of identity to make sure that the owner of the device is doing the actions.
In the privacy protection menu, find the option “Second Space Password” or “Change Password.” Importantly, when creating a new code, make sure it is different from the main space password so that there is no conflict when unlocking. pattern lock, digital key PIN-code.
☑️ Checking before changing password
Once you have a new combination, the system will ask you to confirm it by re-entering it. MIUI may also suggest setting up a biometric unlock (Face ID or fingerprint scanner) for faster access. This is convenient, but remember that the biometrics will still need to be periodically confirmed by entering a digital code.
Resetting password with Mi Account
It's quite common for users to forget their passwords, and fortunately, Xiaomi's ecosystem provides a recovery mechanism through a linked account, which only works if the second space has activated the Internet and is linked to the Mi Account, and without that step, recovery may not be possible.
To use this method, go to the password entry screen in the second space. After several incorrect attempts to enter (usually 5 times), the screen should appear the words "Forgot the password?" or "Forgot the pattern lock." Clicking on this link will redirect you to the authorization page.
Enter the username and password from your Mi Account. If the data is correct and the device is connected to the network, the system will allow you to reset the old code and install a new one. Attention: some versions of MIUI may require a device reboot or a re-authorization in system services after such a reset.
⚠️ Note: If you have recently changed your Mi Account password, wait 24 hours before trying to reset the second space password.This is a security measure to prevent unauthorized access to your data in the event of an account being hacked.
What to do if your Mi Account is not tied
The most difficult situation is when the account is not tied, the Internet in the second space is disabled, and the password is forgotten, in which case the standard recovery methods will not work, the Android security system and MIUI are designed so that the data is not available without the encryption key, which is your password.
The only way out is to completely remove the second space, which is irreversible and will result in the loss of all the data stored inside the clone, with photos, contacts, apps and files destroyed, but this will give you back control of the device and free up the memory you have.
To remove, you need to be in the main space. Go to Settings → Second Space. In the upper right corner, click on the menu icon (three dots or a gear) and select “Delete Second Space.” The system will alert you to the consequences and request the password to unlock the main screen for confirmation.
Why can’t you just reset your password without losing your data?
Once confirmed, the system will clear the dedicated memory partition, which can take anywhere from 30 seconds to a few minutes depending on the amount of data you have accumulated, and once completed, you can create a new second space from scratch by coming up with a new, more secure password.
Using a fingerprint to access
Biometric unlocking makes life much easier by eliminating the need to enter code every time. Xiaomi smartphones can set different fingerprints for the main and second spaces, for example, with your right thumb you open the main screen, and with your index left you open the second space.
You can set it up in the Settings menu → Passwords and Security → Unlock by fingerprint. Here you will see a list of added fingerprints. For each fingerprint, you can assign an action: unlock the main screen or log into a second space, which allows you to instantly switch between modes of operation.
However, relying on biometrics alone is dangerous; the scanner can work poorly with wet hands, gloves or contamination, and once the device is rebooted, the system always requires a digital password or pattern lock to be entered as the primary authorization.
- 👍 Convenience: Instant access with one touch without digits.
- 🔒 Security: A fingerprint is harder to fake than a simple one PIN-4-digit.
- ⚠️ Risk: If the scanner is damaged or the touchscreen malfunctions, access may be difficult.
- 🔄 Always remember your password in case the biometrics fail.
Table: Comparison of methods of protection of the second space
The choice of password type depends on your priorities: the speed of input or maximum protection. Below is a comparison of the basic methods available in MIUI 14 and HyperOS.
| Type of protection | Difficulty in selection | Input speed | Recommended use |
|---|---|---|---|
| pattern lock | Medium | Tall. | For users with good muscle memory |
| PIN-code (4-6 figure) | Low/Mediocre | Very high. | For frequent unlocking in a hurry |
| A complex password | Very high. | Low. | To store critical data |
| Fingerprint. | Tall. | Instant. | For everyday use (main method) |
As you can see from the table, the ideal option is a combination of methods: Use your fingerprint for daily access, but keep in mind a complex password for an emergency. Never use simple combinations like 1234 or 0000, because they are matched in seconds.
Frequent errors and problems when changing passwords
Users often encounter technical nuances that prevent them from changing their passwords. One common problem is that the Change button is inactive or hidden, which can occur if special features (TalkBack, zoom in) are enabled on the device, or if applications with administrator rights are running in the second space.
Another mistake is trying to change the main space password while in the second. The settings menu looks the same, but the changes only apply to the current active profile. Always check the status bar: the second space usually displays a special icon (often a "2" figure or portfolio icon).
There may also be crashes after the system update. If the old password is no longer accepted after the MIUI update, try restarting the smartphone. If the problem persists, there may be a conflict of configuration files, and the only solution is to delete and create space again.
⚠️ Note: Do not try to enter a password more 10-15 Once in a row, the security system can temporarily block the input to 30 seconds, 1 minute or even 1 an hour to prevent brute-force code selection.
Data security tips in a clone
Second space is a great tool, but not a panacea. If someone gets physical access to an unlocked phone, they can switch to a clone if they don't have a separate password for app login. For maximum protection, use the Hide Second Space feature in the settings so that the switch icon doesn't horn your eyes.
Keep your important files backed up from the second space to the cloud or to your computer regularly, and remember that when you reset your phone to a factory-reset, the second space will also be completely deleted without recovery.
💡
Use different wallpapers for the main and second spaces, a visual marker that will help you instantly understand what mode you are in, and not send the work file to a personal chat (or vice versa).
Don’t store passwords from major banking applications in the second space unless they have additional security. Duplicating financial information increases the attack surface. Better use a separate browser profile or password manager with a master password.
💡
The main rule of security: the password from the second space should be unique and do not coincide with the unlock code of the screen, otherwise the protection function loses its meaning when viewed from the outside.
