The situation when you need to untie a Xiaomi phone from your Mi Account occurs quite often: when you sell a gadget, buy a used device with a blocked profile or just change the main smartphone. Mi Account is not just an account, but a key to the ecosystem that provides data synchronization, search for a lost device and protection against theft. However, if you do not follow the correct detachment procedure, the new owner will face an activation lock, known as FRP lock.
In this article, we will take a look at all the legal ways to bind (unlock) through the settings of the smartphone itself, the i.mi.com web interface and special service codes. You will learn how to avoid problems with Find Device and what to do if the password is lost. It is important to understand that modern versions of the MIUI shell and HyperOS have enhanced security protocols, so standard reset methods may not work without prior preparation.
Ignoring the detachment procedure can lead to the phone becoming a “brick” for a new user, requiring the previous owner to enter data each time you turn on. We will look at the nuances of working with Mi Cloud and explain why simply removing an account from the settings menu is a critical step before formatting memory.
Why you need to uncouple the device before selling
Many users underestimate the importance of logging out before resetting. Xiaomi's security system ties a unique device identifier (IMEI) to your login on the company's servers. If you just make Hard Reset with volume buttons, the phone will request the password from the Mi Account that was active before the reset, which is an anti-theft measure, and it is almost impossible to circumvent it legally without the owner's data.
In addition, your personal photos, contacts and notes can remain in the cloud storage. When you sell a device, you risk transferring access to your personal information to a new owner if you do not completely clean and uncouple. Synchronization works both ways, and new buyer photos can theoretically enter your cloud if you do not break the connection.
⚠️ Note: If you buy a used Xiaomi and you see a password request from someone else's Mi Account when you turn on, do not agree to a transaction without a complete reset by the seller. This device may be stolen or lost, and you will not have access to it.
The unbundling process ensures that the device becomes a “clean sheet” for the new owner, especially for NFC-enabled models and payment services, where card and access key binding is tightly tied to the owner’s profile, and improper termination of use can leave a “digital footprint” that will interfere with the correct operation of certain functions of the new user.
Standard procedure for detachment through smartphone settings
The most reliable and correct way to untie your phone is to do so by regular means as long as you have access to the menu and remember the password.This method ensures that Xiaomi servers receive a signal that the device is no longer yours and remove the activation lock.
To start, you need to go to the settings menu. Find the Mi Account section (usually at the top of the list or in the "About Phone" item. Once you log in, scroll down to the "Out" button. The system can request confirmation of a password or code from an SMS for a person. This is standard MIUI security procedure.
☑️ Checklist before reset
Once you log out, it is also recommended that you turn off the device search function, although when you log out correctly, it turns off automatically. Make sure that the status is “Not logged in.” Only then you can start a full reset via the Advanced Settings menu → Reset settings.
It is important to note that some firmware versions (especially China’s CN ROM) may have additional confirmations, and if the system says that the device cannot be unset due to security policies, check for an active Internet connection.
Delete the device via the i.mi.com web interface
If your phone is broken, lost, or just far away, but you need to untie it from your account (for example, you have already sold it and the buyer can’t activate it), use the web version of the service.This method is effective when physical access to the smartphone menu is limited, but you remember the username and password from Mi Account.
Go to the official cloud service website at i.mi.com. Sign in by entering your credentials. Once logged in to the cloud interface, find the Find Device section or smartphone icon in the app menu, and here you will see a list of all the gadgets that have ever been linked to your profile and have an active connection to the server.
| Action. | The result | Conditions required |
|---|---|---|
| Removal from the list | Removes activation blockage (FRP) | Access to the account |
| Data Clearance (Wipe) | Wipes all the files on your phone. | Internet on the device |
| Disappearance regime | Blocks the screen with a message | Internet on the device |
| Sound signal | It's max. volume. | Internet on the device |
Select the device you want from the list. In the control menu that appears, find the Delete or Unplug button. The system will warn you of the consequences: the device will disappear from the trusted list and you will need a new login to activate it again, which is equivalent to logging out of your account through settings.
What to do if the device is offline?
After successful removal in the web interface, it is recommended to wait 5-10 minutes before the new owner tries to activate the smartphone.The servers take time to update statuses and distribute changes to all Xiaomi authentication nodes.
Actions in case of loss of password from Mi Account
The most difficult situation is when you want to untie your phone, but you don't remember the password from your account. Without authorization, standard methods don't work, in which case the first step should be to restore access, not try to "hack" the device, which can lead to a complete lockdown.
Go to account.xiaomi.com and click "Forgot your password." You'll need access to your linked phone number or backup email. SIM-The card you registered for is on your hands, no problem, you will receive an SMS with a confirmation code and you will be able to set a new password.
- 📱 If SIM-The card is lost, restore it in the cabin of the operator - this is the fastest way to return access to the number.
- 📧 If you have email tied, check the Spam folder – emails from Xiaomi often get there.
- 🛡️ If two-factor authorization is enabled, prepare backup codes if they were previously saved.
If you lose your email and phone, you'll have to go through the identity verification process through support, a lengthy process that requires you to provide checks for the purchase of a device or boxes. IMI-Xiaomi technical support strictly ensures that the uncoupling occurs only at the request of the real owner.
⚠️ Warning: Never use third-party programs to “reset” your Mi Account password found in unverified sources, most often viruses or phishing sites that will steal your data but will not help unlock your phone.
Specificity of decoupling on different versions of MIUI and HyperOS
The detachment procedure may vary slightly depending on the version of the operating system. Owners of HyperOS-based devices (the successor to MIUI) may notice a modified security menu interface. The logic of the work remains the same, but the location of the controls has become more intuitive.
Global ROMs can be decoupled instantly when the Internet is available. Chinese versions (CN ROMs), even with Russian installed, can be delayed due to servers in China, sometimes requiring you to switch the region in settings (Settings → Additional settings → Region) to India or Singapore to speed up the synchronization process.
Special attention should be paid to devices purchased under the Trade-in program or in installments, such phones can be blocked by the operator or store at the level of the device.IMEI. The untied Mi Account in this case will not remove the financial lock. IMI-code to a special check-up service on the Xiaomi website or through USSD-team#.
💡
Tip: Before selling your phone, take a screenshot of the About Phone screen with the visible IMI-And then you send it to the customer, and it'll confirm that the device is not blacklisted and is ready for sale.
Also worth mentioning is Family Sharing, if your device was part of a family group, when uncoupling your main account, you may experience synchronization conflicts with your Mi Store purchases, and it is recommended that you leave the family group in your account settings first and then exit.
