2. Unbind payment accounts such as Alipay, WeChat and Taobao.

You can change it directly from the website and directly change the binding mobile phone number; Now Taobao needs the verification code of the original bound mobile phone to change the new mobile phone number. If you can't receive the verification code, you can only apply for mailbox replacement or contact customer service to modify it.

Third, the binding change of email account.

The email account is bound to the mobile phone, especially the work email. If someone logs in, not only will personal information be leaked, but also the confidential documents of the company will be stolen by criminals.
