Did they get the verification code after the operator authorized it?

According to Baidu Library, operators can receive verification codes after authorization. When the user requests access, the application will send a verification code to the user, and the verification code will be sent to the user's mobile phone in the form of a short message. After the user enters the verification code and submits it, the application will request the user's authorization from the operator. If the user is authorized successfully, the operator will provide the application with an authorization code to prove that the user has authorized the application.
