How often does WeChat SMS verification code resume?

WeChat SMS verification code is frequently restored for 2 hours. The frequent two-hour recovery of WeChat SMS verification code is to give users a certain cooling-off period, and also to ensure that users can receive the verification code again when needed. In order to protect the security of user accounts and prevent malicious attacks and abuses, WeChat can reduce the risk of malicious speculation or misappropriation by limiting the frequency of sending verification codes.
