SMS verification code is an effective verification code system by sending the code to the cell phone. Nowadays, many websites and APPs have cell phone verification login, users only need to enter their cell phone number and the correct verification code to log in. Once you have leaked the verification code to others, illegals can log in with your cell phone number, steal your account password and personal information, and even cause the loss of property.
Under normal circumstances, banks or institutions will not ask users for SMS verification codes, so you must be highly vigilant about asking for verification codes.
