Changing an account on a Xiaomi Mi 9 smartphone can be required in a variety of situations: when buying a device from hand, transferring a gadget to another user or wanting to use a separate profile for work and personal purposes. Owners of the popular Redmi Mi 9 model often face the nuances of the MIUI shell, where binding to a Mi Account is a key security element. Incorrect actions when changing a profile can lead to locking the device with the Find Device function, which will make the phone unusable for use without the previous owner’s data.
The process of transitioning to a new account requires a series of actions to completely untie the old identifier. The MIUI security system tightly controls access to data, so simply removing the Service application will not solve the problem. You need to completely deauthorize the device in the manufacturer's cloud services to reset the binding to a specific Mi ID. Ignoring this step often causes a password request after resetting.
In this article, we will discuss in detail the algorithm of actions that will allow you to safely change users. You will learn how to correctly log out of your current profile, clear the cache of services and log in under new data. It is critical to perform full data synchronization before leaving, so as not to lose contacts and photos stored in the cloud. Following the instructions will help avoid common errors and ensure stable operation of the smartphone under the new management.
Preparing the device for a change in profile
Before you start any manipulation of accounts on Xiaomi Mi 9, you need to conduct thorough preparation. Make sure that the device is connected to a stable Wi-Fi network, as the unbundling process may require checking the status of the authorization servers in real time.
Back up all important data, including contacts, messages and media. When changing your account, you often need to completely reset your settings, which will delete all user information. Use the built-in Settings tool → About Phone → Backup and Restore to create a local copy or sync the data to the current cloud before it is deleted.
Remember or write down the password for your current Mi Account, even if you plan to delete it. MIUI security can request ID at any time for critical changes to the system. If you bought a used phone and do not know the password, changing your account without the previous owner will not be possible due to the protection of Anti-theft.
⚠️ Note: Do not attempt to circumvent Mi Account protection by flashing or using third-party software.This may result in a device locking at the server level (IMEU lock).
Check the operating system version of your Xiaomi Mi 9. Up-to-date software ensures that the authorization mechanisms work correctly. Go to Settings → About phone and click on the MIUI version to check for updates. If new security patches are available, install them before starting the user change procedure.
Disconnection of the current Mi Account
The first and most important step is to exit your current profile correctly: simply deleting your account from the sync list is not enough, you need to log out. Open the Services app or go to Settings → Mi Account. In the menu that opens, find the "Log out" or "Delete account" button.
The system will request confirmation of action and may require you to enter a password or code from SMS. This is standard data protection procedure. Once you enter credentials, the system will send a request to the server to unlock the device's association. Make sure that the anchor indicators in the menu have disappeared and the status has changed to "Not authorized".
- 📲 Open Settings and select Mi Account at the top of the list.
- 🔓 Click the exit button and confirm the action with a password.
- 📂 Wait for notification of successful cancellation of the device binding.
Once you exit, check the status of Find Device. It should be automatically disabled. If the indicator is on active color, repeat the exit procedure. Some versions of MIUI require a separate action to deactivate this feature in the security menu.

Cleaning up service data and cache
Even after a formal log-out, temporary files and authorization tokens can remain in the system. Xiaomi Mi 9 is characterized by deep integration of Mi services into the system. To ensure a clean change of user, you need to clear the data of the system applications responsible for authorization.
Go to Settings → Apps → All Apps. Find Mi Services and Accounts and Syncs in the list. Select Memory for each and click Clear Everything or Reset, which will delete saved passwords and cache, preventing automatic login under the old login.
| System component | Action. | The result |
|---|---|---|
| Mi Services. | Clearing the data | Resetting authorization tokens |
| Google accounts | Deletion of account | Uncoupling from Google Play |
| gallery | Clearing the cache | Removing cloud previews |
| Conductor | Clearing the data | Resetting paths to the cloud |
It is also recommended to check Google accounts. Go to Settings → Accounts and Sync → Google. If there is an old account, delete it. This will prevent sync conflicts and errors when working with Google Play Market after logging into a new profile.
Registration and login to a new account
Now that the device has been cleared of the previous user’s traces, you can start registering a new Mi Account. If you already have an account, just enter the data. To create a new profile, you will need a phone number or email address. The registration process for the Xiaomi Mi 9 is standard and does not require complex manipulation.
Enter your phone number in the sign-up box. The system will send an SMS with a confirmation code. In some regions, you may need to select a country code from a list. Once you enter the code, come up with a strong password that will be used to access the cloud storage and other services of the Xiaomi ecosystem.
Once you've signed up, the system will suggest you set up sync settings. Carefully review the list: contacts, messages, notes, voice recorder. It's recommended that you enable only the necessary data synchronization to avoid overloading cloud storage with unnecessary garbage. The new account will immediately become the main one for all system services.
It is important to note that when you sign in to a new account on an already configured phone, some system applications may require a reboot. If you notice themes or widgets not working properly, reboot the device through the power menu, which will update the system configuration files.
Synchronization and services setting
After you sign in to your new Mi Account, you need to configure sync options for Xiaomi Mi 9. This will keep your data safe in the cloud. Go to Settings → Mi Account → Sync. Here you will see a list of all the applications that can transfer data to the server.
Activate sync for contacts and calendars first, which will allow you to quickly recover important data if your phone is lost or broken by simply logging in to an account on any other device, and you should also pay attention to synchronizing Wi-Fi passwords and call lists.
- 📸 Gallery: Turn on the photo to the cloud for automatic upload.
- 📞 Contacts: Critical to Keeping a Phone Book.
- 📝 Notes: synchronization of text and voice notes.
Note the amount of free space in the cloud. Xiaomi Cloud's baseline tariff provides 5GB of free space. If you plan to store a lot of photos, consider expanding storage or using alternative services like Google Photos to back up media content.
⚠️ Note: When you enable gallery sync, make sure that the source files are not deleted from the device automatically. Check the settings "Free space" in the Gallery app.
Addressing common problems
While changing your account, Xiaomi Mi 9 users may encounter various technical difficulties, and one of the most common problems is the network error when trying to log out. If the "Exit" button is inactive or the process is stalling, try changing the type of connection from Wi-Fi to mobile Internet or vice versa. IP-addresses for frequent requests.
Another common situation is requiring a password after resetting, even if the account has been deleted, which happens if the Find Device function was not disabled before reset, in which case the only legal way to unlock the phone is to enter the details of the last active account, without which the device will remain locked.
What to do if you forget your old account password?
There may also be a problem with dual authorization on Google services. After changing your Mi Account, the system may request a re-sign in to Google Play. This is normal. Just enter your Google account details. If the system writes an "authentication error", clear the data of the Google Play Services application through the application menu.
