Tik Tok keeps sending me the same verification code. What's going on here?

Maybe the mobile phone number is wrong, so the text message was sent to your recipient, but the person who really wanted to register was not found. Click for the first time to get the verification code. But he never received it. After a while, he may click again and get the verification code again. So many times. Finally, I found that the original mobile phone number was wrong. This is to change the mobile phone.

The second possibility is the bombing of mobile phone verification code, but the bombing of mobile phone verification code is generally a lot of different signatures in a short time. If it's just a signature, the first one is more likely.

3.

As long as the verification code is not leaked to others, there is generally no security problem.
