What does the verification code of SMS mean?

SMS verification code was born to improve account security. With the advent of the Internet era, people handle various businesses online more and more frequently, and how to ensure the security of accounts has become the most important. SMS verification code is a double authentication mechanism, that is, on the basis of account password, a verification code is sent to the user by SMS to confirm whether it is my operation. This method can effectively prevent the account from being cracked.

SMS verification code is widely used. Nowadays, many enterprises need to verify the identity of users through SMS verification code for important operations such as registration, login and password retrieval. In addition, some financial institutions also use SMS verification code to protect account security, such as bank card binding, transfer, transaction and other operations need to confirm identity through SMS verification code.

Of course, SMS verification code also has its limitations. If hackers invade the operator's server and get the SMS verification code, they can easily break through the security barrier of double authentication. In addition, if the SMS verification code is leaked by the user, it is useless. Therefore, it is also important to protect the security of SMS verification code.
