TIP The Password Challenge/Response: Your Password Challenge will be presented to you when you request to have your password reset. Your password will only be reset when you respond with the correct Password Challenge Response. The intent of the password challenge and response is to prevent others from resetting your password.
Suggestions: The challenge should be something easy for you to remember, but, not widely known by others, for instance "What is your dog's name?" or "What is your mother's maiden name?".
