Owning a modern Xiaomi smartphone is inextricably linked to using the Mi Account cloud service, a single key to accessing contacts, finding a device and using the brand ecosystem. However, situations vary: selling a gadget, handing it over to relatives or simply wanting to change the main mailbox require understanding how to properly and safely untie the profile from the hardware.
Simply removing an app or cleaning up a cache won't help. System binding works at the server and firmware level of MIUI or HyperOS. If you sell a phone without following the unblocking procedure, the new owner will face activation lock and you risk losing control of your data, so it's important to be clear about the difference between logging out and completely removing the device from the trusted list.
In this article, we'll take a look at all the legal ways to manage binding, and you'll learn how to use standard methods through the settings menu, how to use the web interface for remote management, and what to do if access to your phone is lost. Remember, password-free undressing is only possible if you have access to a recovery mail or a phone number linked to your profile.
Why you need to untie the device before selling
Many users underestimate the importance of logging out, believing that simply resetting your phone to factory settings is a dangerous misconception. Find Device is built deep into Xiaomi's security system. Once the data is reset, the phone will request a password from the last Mi Account used when it first turns on.
If you don't do the right thing, the smartphone will become a brick for the new owner, unable to activate the device, log in to the menu, or use basic functions, and even more so, while the device is listed on your behalf, it can receive notifications, sync new photos or messages if the SIM card suddenly ends up on another device and the cloud is active.
The undocking is also necessary to free up the slot in the list of trusted devices. Xiaomi services have a limit on the number of gadgets that can be tied to a single profile at the same time for sync and search. Old, sold or lost phones need to be manually removed so as not to create confusion in the future.
⚠️ Warning: Selling a phone with an active Mi Account on the device is a risk of leaking your personal data.A buyer could theoretically access your cloud photos and contacts if a full exit and cleanup is not done.
There are also financial aspects: If your account has a bank card attached to pay in the Mi Store or within gaming applications, having an active session on the sold device can lead to unauthorized write-offs.
The standard way of detachment through smartphone settings
The most reliable and correct method of disabling is to perform it directly on the device, as long as you have physical access to it and remember the password, which ensures that the server receives a signal to change the status of the device, and the activation lock will be removed automatically.
You need to get to the profile management menu first. The interface may vary slightly depending on the version of MIUI or HyperOS, but the logic remains the same. You need to find the section responsible for accounts and sync.
- 📱 Open the Settings app and go to the topmost section with the account name.
- 🔓 Click on the Sign Out button (or “Delete Account” in some versions).
- 🔐 Enter your Mi Account password to confirm your identity.
- ✅ Wait for the message of successful disabling and disappearance of the profile avatar.
Once you do this, the phone will stop syncing, but to keep the experiment clean, you should also check the list of trusted devices through the browser, which will be discussed below. Sometimes it happens that the phone itself has exited, but the server has tails.
☑️ Checklist before selling the phone
It's important not to confuse just leaving your account with removing your device from your trusted list, and in some cases, especially when you're preparing to sell, you'd better do both, go to the phone menu first, then check the web interface.
Delete the device via the i.mi.com web interface
If the phone is already owned by the new owner, or you just want to remotely manage the list of your gadgets, the official Xiaomi Cloud website will become an indispensable tool. This method allows you to “untie” the device from your account even without physical access to it, provided that you remember the username and password.
Go to i.mi.com from a computer or other smartphone, log in using your credentials, and when you log in, you'll see a dashboard that displays every device ever connected to your profile.
| Status of device | Interface action | The result |
|---|---|---|
| Online (online) | The "Exit" or "Delete" button | The device is unlocked, the data is deleted |
| Offline (offline) | Remove from the list button | The lock will be removed the next time you connect to the network |
| Unknown device | Change of password | Forced withdrawal from all sessions |
Find a smartphone sold or given away on the list, usually with a model (like the Redmi Note 10) and the date of the last connection. Click on the device icon to reveal the detailed menu.
In the window that opens, select Remove device. The system will request confirmation, warning that this action will remove the activation lock, a critical step to transfer rights to a new user.
What to do if the device is not removed?
What to do if you forget your account password
The forgotten password situation is one of the most common and complex. Without proof of identity, Xiaomi's security system will not allow you to untie the device, considering such actions an attempt to steal, but you can restore access if you have the data to restore.
The first step is to try to restore through the login screen. On the login page, click on the link “Forgot your password?” The system will offer several options for verification: a code from the SMS to the associated number, a backup email letter or an answer to a secret question (if it was installed long ago).
If a phone number or email is not available (for example, a SIM card has been lost many years ago), the process becomes complicated: you will need to go to id.mi.com and select the procedure for restoring your account, which may require a passport scan or a receipt to prove that you are the owner.
- 📧 Try to remember what mail could be used during registration (often it is old mailboxes Mail.ru or Yandex).
- 📱 Check if the SIM card that was inserted into the phone when you first set up is active.
- 📄 Find a warranty card or check from the store – they may be needed for technical support.
⚠️ Warning: Do not use third-party software to hack or bypass your Mi Account. At best, you will get a virus, at worst, permanently lock the device at the hardware level (IMEU Blacklist, after which it will be impossible to restore it even in the service.
After successfully restoring your password, immediately change it to a more complex one and make sure to write it to a secure location. Then perform the detachment procedure through your settings or site as described in the previous sections.
💡
Keep your smartphone purchase check electronically (photo or scan) immediately after purchase, the only document that can help prove ownership of the device in the event of a lock.
Problems with activation blocking (FRP and Mi Lock)
Activation blocking is a security mechanism that works if the device has reset to factory settings (Wipe Data), but was not previously logged out.
This is a feature designed to protect against theft, and if a thief steals a phone and dumps it, he can't use it, but if you forget the password yourself, the phone becomes a useless piece of plastic and glass, and you can unlock it only by entering the correct data.
There is a myth that flashing your phone helps to unblock. In modern versions of MIUI and HyperOS, the server-side binding is secured and tied to a unique device identifier. Changing the software won't delete the password request when you boot.
If you bought a phone off your hands and you encountered one, the only legal way to do that is to contact the previous owner, and he has to remotely, through i.mi.com, remove that device from his trusted list, and then just reboot the phone and the lock will disappear.
Google Account Untied (FRP)
In addition to the Xiaomi ecosystem, all Android smartphones have Google FRP (Factory Reset Protection) protection, which works in a similar way: if you reset your phone, it will require a password from the last Google account.
To avoid problems, you must also log out of Google services before selling. Go to Settings → Accounts and Sync → Google. Select your email address and click “Delete Account” or “Sign Out”.
Only after deleting both Xiaomi and Google profiles can you safely perform a full reset, which ensures that the new owner does not encounter lock screens and can customize the phone as his own from scratch.
💡
Full preparation of the phone for sale includes exiting the Mi-account, exiting the Google account and only after that - resetting to factory settings through the Recovery menu or Settings.
