Why do I need to enter SMS verification code to log in?

Hello, if you are prompted to need SMS verification code when logging in, it is because if the system detects that the user is not logging in with a common device, it will require SMS verification to ensure security. If you log on to a common device, but still require SMS verification, it is recommended to check whether the nail version is the latest, and try to upgrade the version or uninstall and reinstall it. If the user indicates that it is the latest version, please collect user information and submit the BUG approval form in the nail service experience to the technicians for investigation and handling.
