What does it mean to bind the mobile phone number?

Binding the mobile phone number is to associate the application account with the mobile phone number, so that it is easier to confirm the identity when logging in to the application and enjoy other services such as SMS verification code.

After binding the application account with the mobile phone number, the mobile phone number is the login name. As long as you bind the mobile phone, you can also tell you intimately whether this mobile phone is registered for Taobao or Alipay. In the case of forgetting the login password, the system will also inform the operation process after forgetting the password, and send the verification code of the mobile phone to the bound mobile phone, so as to facilitate the user to retrieve the account, modify the password and use other functions.

An information security agency recently reminded that because some of the original users' online accounts can be accessed through the mobile phone number verification function, the cancelled and resold mobile phone numbers have security risks.

Operators will recycle the deactivated and abandoned mobile phone numbers, "freeze" them for a period of time and then resell them, which is conducive to making full use of telecom number resources. But nowadays, whether it is social account or online payment, binding mobile phone number and SMS verification has become a common way to ensure account security. If we don't face up to this situation and leave some numbers in a state of "poisoning", the "old numbers" will breed "new risks".
