Can I merge a Xiaomi Account based on a third-party account with an account associated with my phone number?

You can't merge two different Xiaomi Accounts together.However, you can add your third-party account or phone number to another Xiaomi Account.

1. You can check how to add your phone number to a different Xiaomi Account here.
2. If you want to add a third-party account, sign in to your Xiaomi Account first.
   • On a computer, visit id.mi.com, sign in to your Xiaomi Account, click "Accounts & permissions", select the account you want to remove, and click "Remove".
   • Alternatively, go to Settings > Xiaomi Account > Account security > Third-party accounts on your Xiaomi device.
3. Remember that if you haven't added any additional information to your third-party account, you'll only be able to sign in using your account ID and password.
