Why are some questions good, fair, or poor? The Full List of Security Questions below answers this.

Wait! Some GOOD Questions are Still BAD…

Even if a question is good, some people will not use it, because it doesn’t work for them. Example: name of the place your wedding reception was held – but if I haven’t been married I won’t use that question. So which GOOD questions will get used?

From over 175 questions I took the best and conducted a survey of which questions people would use. There are now over 350 responses. I also rated each question based on the 5 criteria above, ranked the questions, and provided rationale for each question. The results are included in the Full List of Security Questions.
