You can't bypass those questions, nor can you choose alternatives other than the six predefined questions. If you're worried that a thief with a search engine can guess those answers, do as I do and ... be creative. For example, you can answer the three security questions with a three-word passphrase of your own, entered one word at a time. Or, if you'd prefer to bypass the whole feature, just mash the keyboard to create random "answers" that no one (including you) could possibly guess. If you choose either option, don't blame me if you forget your password.
