What is the verification code SMS? Tianyihong takes you a minute to understand the verification code message.

Verification code SMS is a security verification method, which is usually used for identity authentication, account registration, login confirmation and other scenarios. When the user needs to perform sensitive operations, the system will send a short message to the user's mobile phone, which contains a string of digital verification codes. The user needs to input the verification code into the system to complete the verification and continue the operation. The main function of verification code SMS is to prevent information leakage and malicious attacks, thus improving the security of the system. At the same time, because of its real-time and universality, SMS is more convenient and reliable than other methods in verifying user identity. It should be noted that due to the delay and risk of SMS transmission, as well as the limitation of receiving number and SMS sending channel, it is necessary to ensure the accuracy of sending number and the reliability of sending channel when using verification code SMS.
