Disable security question

Is this checkbox removed from contao 4?
I cant find this checkbox in formgenerator settings. Can someone tell me where is located?

Which module are you referring to?

Form generator. Contao is 4.4.35

There is no option like that in any Contao 3 or 4 for the form generator. In order to have a security question, you need to add that form field to the form generator. Keep in mind that Contao 4 uses a honepot implementation, i.e. you, as a regular user, will not see the security question.
