Security questions are DUMB. They are the exactly same authentication mechanism as password (i.e. proving you know some piece of information). So you basically have multiple backup password in case you forgot the first one. But worse. If you create a different password for them. Because you rarely use those answer, you won't be able to remember them when they are actually needed. If you generate them with your password manager, then when you loss your password you loss them too. If you actually answer the questions with real information, you basically created a weak password. All in all, security questions is a terrible idea.
