How would a code help? The victim has already bought into the social engineering. If the person on the phone asks the user to read out a code, they will. If the person on the phone asks them to enter a code (i.e. the version of this kind of prompt where the user needs to enter a code on the phone matching the one showing on the login page), they will.
Every step you make someone who is being socially engineered jumo through, is an extra chance for them to realize what is happening, especially if those steps contain warnings.
