Account management on Xiaomi, Redmi and POCO smartphones is a fundamental part of the security and usability of the device. Often there is a need to untie email: whether it is selling a gadget, transferring it to another family member or simply wanting to clear the list of authorized devices from old links. The process of deleting a Google account or Mi Account on the shell of MIUI or HyperOS has its own features that you need to consider so as not to face a lock.
It is important to understand that simply “delete” the mailbox is technically impossible – you only untie access to it from a specific physical device. All emails, contacts and data synchronized with the cloud will remain intact on the provider’s servers. However, local data that was not synchronized can be lost, so you should take care to create a backup before starting any manipulation.
In this article, we will take a look at the algorithms for different versions of the operating system, look at the nuances of deleting the main account and answer questions related to theft protection, learn how to safely manage access, understand the difference between logging out and completely removing a device from the trusted list, and learn how to avoid activation blocking FRP.
Preparing for account deletion and backup
Before you start taking action on the settings menu, you need to perform a number of preparatory procedures. Untie account, especially if it is the only or primary mail on the device, can lead to the loss of important data if the sync was not working correctly or was disabled. Make sure you have access to the Internet and remember passwords from accounts.
The first step is to check the sync status. Go to the settings and make sure that contacts, notes and calendar are successfully uploaded to the cloud. This is a critical step, since after deleting the account, the local copy of the data on the phone will be erased. For Xiaomi users, it is especially important to check the Mi Cloud cloud, as it often duplicates data from Google Contacts.
☑️ Preparation for mail removal
If you plan to sell your phone or give it away for repair, simply removing your email may not be enough — it will require a complete reset. But if the goal is just to clean up your account list, make sure that the device is debugging on USB (if you are an advanced user) or just check for free space for temporary system files during the profile restructuring process.
Deleting Google account on Xiaomi and Redmi
The procedure for detaching the main email service from Android on Xiaomi devices is standardized, but the paths in the menu may vary slightly depending on the version of MIUI. Google account is key to the operation of the Play Market store, so its removal will limit the functionality of the smartphone until the moment of re-authorization.
To start, open the Settings app and scroll down to Accounts and Sync (or simply Acca/Naccounts in new versions of HyperOS). In the list that opens, you will see all the associated services. Select the Google logo, then tap the desired email address. The system will warn you that deleting your account will cause the associated data to disappear from that device.
What happens to your data after you delete your Google account?
Click the Delete Account button and confirm the action by entering a password or graphical key to unlock the screen. If the system requires a password specifically from a Google account, enter it. This is a security measure that prevents the deletion of mail by unauthorized persons who have access to the unlocked phone.
💡
Deleting a Google account does not delete the email box itself – it continues to exist and can be logged in from any other device or computer.
Mi Account (Mi Cloud) on the shell of MIUI and HyperOS
In the Xiaomi ecosystem, Mi Account plays an even more important role than Google, as it is deeply integrated into the device’s security and search features. Deleting or unbundling Mi Account is mandatory before selling, otherwise the new owner will not be able to activate the phone due to activation blocking.
Go to Settings and select the top item with your name and your avatar (Mi Account). Scroll to the bottom. Here you will find the "Off" button. When you click on it, the system will require you to enter a password from Mi Account. This is a mandatory procedure to confirm that the owner of the device really wants to untie it from his profile.
Once you enter your password, the phone will disconnect from the Mi Cloud servers, sync photos, notes, voice recorders and themes will stop. If the device has "Find Device" enabled, it will only be deactivated after successful exit. In some cases, if two-factor authorization is enabled, you may need to code from the SMS.
⚠️ Warning: If you forget your Mi Account password and log out (or reset), your phone will turn into a brick the next time you activate it, and unlocking it without a password or a purchase check will be extremely difficult and expensive.
It's important to distinguish between just leaving your account and removing your device from the trusted list on your site, so if you have your phone, you just have to go through the settings, and if your phone is lost, you have to go to i.mi.com and remove the device from the list to unblock it.
Removal of third-party email clients (Mail, Yandex, Outlook)
In addition to system accounts, Xiaomi smartphones often use third-party mail aggregation apps, such as Xiaomi’s standard Mail app (based on Microsoft’s engine or its own), as well as apps from Yandex, Mail.ru or Outlook.
To remove your account from the standard Mail app (an envelope icon), open the app and go to settings (usually a gear icon or three dots in the corner). Select Account Management or just click on the avatar. In the account list, find the one you want and select Delete Account or Sign Out. This will break the application's connection to the server.
- 📧 Yandex Mail app: Open the app, click on the profile icon, select Settings, scroll down and click “Exit account” or “Delete account».
- 📩 Microsoft Outlook: Click on the avatar or home icon in the top left corner, then the gear icon (settings). Under Mail accounts, select the address you want and click on Delete email account».
- 📮 Gmail: Although Gmail is system-based, you can switch between accounts inside the app itself. To remove access in the app, you need to go through the general Android settings, as described in the second section.
💡
If you use corporate email (Exchange), deleting your account from your phone settings can also remotely erase your company’s security policy. IT-division.
Once the account is removed from the application, the emails will no longer be sent to that client, but will remain accessible via the web interface or other email programs, which is convenient for temporarily disabling notifications or separating personal and work space.
Resetting and complete data cleaning before selling
If your goal is to sell a Xiaomi, Redmi or POCO phone, simply deleting accounts is not enough, you need to perform a full reset to factory settings (Hard Reset), which ensures that the buyer gets a clean device without your personal files, Wi-Fi passwords and browser history.
Critically, before resetting, you must manually delete all accounts (Google and Mi Account) through the settings as described above. If you just turn on the reset without leaving your accounts, FRP (Factory Reset Protection) protection will work. The phone will lock when you turn on and will require a password from the last used Google account.
Settings → About the phone → Reset settings → Erase all dataAfter you go down this path, the system will suggest you enter a pattern lock or unlock password, then you will be warned that all data will be destroyed, confirm the action, the phone will restart, and the cleaning process will begin, which can take from 5 to 15 minutes.
| Action. | Impact on data | Password requirement | Risk of blocking FRP |
|---|---|---|---|
| Deletion of account in settings | Data is erased from the phone, stays in the cloud | Account/screen password required | No. |
| Reset without leaving the account | Completely delete data from your phone | Screen password required | High (locking when switched on) |
| Reset after leaving accounts | Completely delete data from your phone | Screen password required | No (safe to sell) |
Once the reset is complete, the phone will greet you with a screen of initial setup, as if you had just bought it from a store.
FRP blockage problems and their solution
FRP (Factory Reset Protection) is an Android security mechanism that prevents the stolen phone from being used after resetting. If you reset your phone without deleting your Google account, the system will require you to enter the username and password from the account that was synced last when you first activate it.
Often, users have a problem remembering the password from the lock screen, but they have forgotten the password from the Google account that was on the phone, in which case, standard methods of unlocking the device will not work, and trying to guess the password will only temporarily block the ability to enter.
⚠️ Warning: Do not try to use questionable software to hack» FRP, This can lead to the installation of viruses on your computer or the final breakdown of the phone's software.
The only legal way to restore access is to use the Google account recovery procedure via a computer or other phone (via the Google account site), if you remember the password, it will be enough to enter it when you activate it, and if an account has been deleted or restored, you may need to wait 24 hours before trying to log in on the reset device.
