How can I receive SMS verification code without postal online banking?

Maybe someone else filled in the wrong number.

In the case of receiving the verification code without opening postal online banking, it may be that someone else has filled in the wrong mobile phone number, but if you often receive verification codes from various banks and small loan companies, you'd better check the credit information to see if anyone else has used your ID card to handle various credit cards and loans.

The verification code is a public automatic program, which is used to distinguish whether the user is a computer or a person. Verification code is a popular way in many websites, which can not only prevent malicious password cracking and forum flooding. In addition, it can effectively prevent hackers from constantly trying to log in to specific registered users and use specific programs for violent cracking. Although it is a bit troublesome to log in with verification code, this function is necessary and important for the password security of netizens.
