I don't think having 3 secret questions is a good way for recovering password in case you forgot it, and this can potentially be abused and be security nightmare.
Even in Bitcointalk forum we have this option but using it is not recommended because someone could guess your secret answer, and humans are bad in keeping secrets and making random stuff.
Secret Question:
To help retrieve your password, enter a question here with an answer that only you know. Using this feature is not recommended. Anyone who guesses your secret answer will have access to your account. It's like a second password.
