How do I log into my child's OS X account (under parental control) without knowing the password? My child (single-digit age) and I share the same Mac Mini. She has an account under parental control. However, she doesn't want to give me her password.

How can I log into her account? Both from (1) she is not logged on; or (2) she is logged on but locked the screen.

Thanks!
Technically, you can reset her password.

From a privacy point of view, you have to be clear with your policy. If you let her have an account with her own password, you implicitly agree that you should not log into her account without her approval. The solution is then to ask her to type her password so that you can use her account.
