What drives me crazy is that it doesn't matter how well I design my passwords if companies immediately sabotage them with their laughable "security" questions. "Pick one of these security questions carefully chosen for you by our marketing director's 4th grader: What was Mommy's maiden name? What was your first pet's name?..."

So now a hacker can just claim to have forgotten my password, google for the town I grew up in or mother's maiden name or try a list of the top 100 pet names, and not have to deal with my billion-year clever password at all. So they allow you to harden the front door's security as much as you like but require you to pick one of their six easy-access window designs for the side of the house just in case you (or anyone else) are unable to get through the front door.

I can improve security by providing the wrong answer, but then I'll have to record it and won't remember it if surprised by a challenge (on the phone for example). What I always want is the option to create my own security question, because I can design one that only makes sense to me but that I can reliably answer from memory.
