What is it that everything on Apple's mobile phone needs a verification code? How to solve this problem?

You can refer to the following methods:

In this case, you should first click Settings, and then click our avatar at the top of the Settings page.

2. Then find "iTunes store and App Store" in the apple ID interface, and then click your own Apple ID, as shown in the figure.

3. Select "View Apple ID" in the pop-up dialog box, and then enter the password in the new page input box.

If you forget the password, you need to modify it. If the password is correct, click "Finish" in the upper right corner of the account setting interface, and then return to the App Store to download again.

App Store (part of iTunes Store) is a service software for iPhone, iPod Touch, iPad and Mac, which allows users to browse and download some applications developed for iPhone SDK or Mac from iTunes Store or Mac App Store.

The ID lock is a function to turn on the "Find My iPhone" function under iOS 7 and later systems. When the system is in the "Find My iPhone" state, you need to reactivate the Apple ID account on the bound mobile phone to enter the desktop.

To unlock the ID lock, the more reliable method at present is to let Apple activate the ID lock team to close the ID lock. After entering the system interface, users will receive email prompts from the Apple team, asking for original invoices, business information and product information. For example, for the Hong Kong version of the mobile phone, it is also necessary to provide a Hong Kong and Macao pass for purchase.

Apple's email reply time ranges from 2 days to more than ten days. The only thing a user can do after applying for unlocking requirements is to wait. Only some mobile phone users of the Bank of China can produce materials that meet Apple's requirements. Other second-hand mobile phones are all counted as mobile phones with irregular channels and cannot be unlocked.
