What is the innovative ipad id verification code?

The id is bound to the mobile phone, and the mobile phone will prompt whether it is allowed or not and provide a 6-digit verification code. Click Retry on the ipad, enter your apple and id, and then enter these 6-digit verification codes continuously to download the app on the ipad.

With two-factor authentication enabled, only you can access your account on trusted devices or web pages. When logging in to a new device for the first time, you need to provide two kinds of information: your password and the six-digit verification code automatically displayed on the device you trust or sent to your phone number. After entering the verification code, you confirm that you trust this new device. For example, if you have an iPhone and want to log in to your account for the first time on a newly purchased Mac, you will be prompted to enter your password and the verification code will be automatically displayed on your iPhone. Because you can no longer access your account by entering a password, two-factor authentication significantly enhances the security of Apple ID and all personal information stored through Apple. After logging in, you will not be asked to enter the verification code again on this device unless you completely log out of the login account, erase the device data or need to change the password for security reasons. When you log on to the Web, you can choose to trust your browser, so you won't be asked to enter the verification code the next time you log on from this computer.
