A lesson we can take from this is just because they are supposed to be security questions based on private and personal information, doesn't mean you should play along.
Why should the answer to where me and my spouse met really be where we met? Why couldn't my answer be where Lucille Ball met Ricky Ricardo? Why couldn't my childhood street address be Evergreen Terrace?
Add a layer of security by creating an entirely different alter ego with a whole history behind it, and use their birthday, maiden name, etc, instead of what somebody can look up in public records, or find out from people close to you.
