Re: Date of birth
The favorite trick I've picked up recently to deal with offensively restrictive secret question fields is to provide a similarly offensive answer. "What is your mother's maiden name?" is answered by something like "Sod off and ask me something better". Should even this get compromised, this guarantees that the guy trying to social engineer a password reset instantly infuriates the representative on the phone and will be grilled with even more scrutiny and suspicion. Win-win.
