Given how "security questions" have been handled in the past, i.e. to be anything but, my response to that sort of thing is to type in random text and usually a lot of it. I also don't see how it increases the security. If the email address of the user has been compromised, it is likely that the intruder would have an easy time finding the correct answers to the questions.
Use a password manager.
For secret questions, make up an answer, note the answer in your password manager.
Good luck with monitoring email to figure out the answers....
