Is it safe to get SMS verification code by mobile phone input method?

It is relatively safe to obtain SMS verification code by mobile phone input method, but it is not absolute.

SMS verification code is a trigger message, which will be sent to the target mobile phone after clicking Get. Large websites, especially shopping websites, generally provide SMS verification code function. For websites, the main function of SMS verification code is to prevent users from maliciously registering and obtain the most authentic user information.

SMS verification is a double-edged sword, because it is like a secret door with an alarm. For payment, the alarm can play a certain warning role, and the secret door can help us quickly retrieve the password when we forget it. The secret door and alarm work at the same time, ensuring property to a certain extent.
