Quote from: "zsolt"To change your login password he needs to know your current login password.
Put yourself in the role of a thief, how would you do it? You cannot login into your mac if you do not know the user password....
This is now a bit off topic, but nevertheless, feel free to ask if it is still unclear.
Again I apologize if I am not understanding correctly but I thought that anyone with an install disk could change the administrator password, as explained here <http://support.apple.com/kb/HT1274>?
By the way, I think this is on topic since using Espionage in the way you suggested depends on it.
Thank you,
