I was creating a Minecraft account for my daughter (with her sitting next to me) and when we looked at the security question choices she asked, “Why does it ask for mother and father instead of just parents?” Indeed. For a security question “In what city did your mother and father meet?” there are assumptions that belong in 1965 not 2013. My daughter has a Mommy and a Momma. If the question is “In what city did your parents meet?” then she could easily answer it.
She has an additional question to ask herself with security questions about your mother’s middle name or father’s middle name. Which mother? Or, for some of her friends, which father?
It’s not a problem when there are plenty of choices for security questions. The Minecraft registration form has some questions my daughter can’t answer and more than enough questions she can answer. However, I see a lot of security questions, for account registration, that don’t have enough options. In those cases I end up just making up an answer and then recording it somewhere so I don’t forget it. That defeats the security.
