this problem also occurs in our project. For SMS verification code login, users can log in by entering their mobile phone number and SMS verification code.
if you don't have this user, register it and log in directly.
our solution is to get a token before calling the SMS verification API. Token has a time limit and is bound to mobile phone numbers and device numbers. When the token expires, you must retrieve it before you can call the SMS API. The API for sending SMS messages must carry a valid token before it can be called. So as long as you make sure that the token access and encryption mechanisms are not cracked.
just in case, you need to add mechanisms such as ip blacklist, number limit, configuration of graphic CAPTCHA, and so on.
