Inexplicably received Tik Tok verification code.

Protection provided by verification code:

SMS verification code can not only prevent attacks from the army and robots, but also verify our personal identity. Whether you apply for a bank card or register some accounts, you need a verification code to confirm your personal identity information, so you use the SMS verification code function in the process of real-name authentication.

So the main function of SMS verification code is very obvious. In addition to identity verification and property security verification in payment, it is also an important bridge for merchants and users to easily establish trust relationship. So I have to say that SMS verification code is now an indispensable part of our lives.

It is also the existence of SMS verification code that allows us to use various applications safely and securely in today's society.
