Verification code is a fully automatic program, which is used to distinguish whether the next operation is performed by a computer or a person. By adding the verification code function, malicious password cracking, ticket brushing and forum flooding can be prevented. Effectively prevent the violent cracking of continuous login attempts.

The core of setting verification code is to set a question. This question must be generated by a computer and the answer must be correct. But the computer can't answer this question, and it must be done by human beings. After setting the topic, you can judge whether the computer is operating or the person is operating. Because the computer can't answer this question, the user who can answer the correct answer can be considered as human.

SMS verification code is the most effective verification code system. Because it is not the same machine that needs to identify and fill in the verification code. This means that under normal circumstances, only the account owner can fill in the SMS verification code correctly.
