Why did Ctrip inexplicably send me a verification code?

Ctrip will inexplicably send a verification code. The possible reasons are:

1. Generally speaking, the verification number is only valid if it is sent to the corresponding mobile phone and logged in correctly. If you receive the verification code inexplicably, it may be that the mobile phone number is leaked for some reason.

2. For some reasons, the mobile phone number is bombarded by criminals using short messages, and spam messages such as verification codes are constantly sent to mobile phones; You can try to use third-party mobile phone housekeeper and other software to set up harassment interception to minimize harassing text messages.

In addition, if some verification codes have nothing to do with banks, Alipay, WeChat and QQ, there is no problem. If so, be sure to change the password in time and take other security measures.
