How to register Xiaomi account
You only need to register Xiaomi account with your mobile phone number or email address. A digital ID account will be assigned to your mobile phone number or email address. This digital account will only display a set of numbers on the mobile phone, and the middle number will be hidden. Don't worry about the security of the digital account, just remember the mobile phone number or email address you used when registering.
How to retrieve the password
If you forget your password, or your mobile phone number and email address have been deactivated, you can go to mi.com, Xiaomi.com or i.mi.com or millet cloud, click Login, and then click Forgot Password to retrieve your password with your mobile phone number or email address.
How to Unbind an Account
If your mobile phone system has been updated to MIUI7 and you can't unbind your account, there will still be a Xiaomi account prompting to enter a password to activate your mobile phone after booting. At this time, you can consider downgrading the mobile phone system to MIUI6, or contact Xiaomi for help after sale.
