Xiaomi 3 mobile phone prompts for the activation code. What is this?

That is the Xiaomi account in the mobile phone.

1. Generally, Xiaomi accounts are registered with mobile phone number or email number, which is Xiaomi's account. After registering the account, the system will randomly assign a group of digital ID accounts to the user to prevent the user's mobile phone number or email number from being leaked, and only one group of digital accounts will be displayed on the mobile phone.

2. If the Xiaomi account is not registered by the user on Xiaomi. Com, and there is indeed a set of digital ID account on the mobile phone, which is actually registered by the user himself. The user used Xiaomi mobile phone for the first time, and continuously clicked Next in the boot step without careful operation. By default, the system registers the account with the mobile phone card inserted into the mobile phone, and automatically sets the password.

Users can go to Xiaomi. Com or millet cloud, click Forgot Password and use their mobile phone number or email number to retrieve the password.

3. If the mobile phone number and email address used when registering the account are no longer used, or the mobile phone is not the user's own, but there is Xiaomi's account on the mobile phone, if the system is below MIUI7, you can cancel the account on the mobile phone by double clearing or triple clearing without knowing the password. However, if the mobile phone system is already a MIUI7 system and the account cannot be untied, then it can only be suggested to go to Xiaomi for after-sales solution.
