FileVault is a form of encryption. There is no way to access encrypted data of any kind without knowing a password.
A legacy FileVault can be unlocked either with the user's password or with the master password that was set in the Security preference pane. A FileVault 2 boot volume can be unlocked with the password of any of the local users authorized to do so.
