I'm not certain, but I don't think just anyone can use that account. Guys, please correct me if I'm wrong. If you are concerned that you might lose/forget your password some day, create a secondary user account with a very complex password that you can keep somewhere secure (not on the system itself ). Also, be sure to add that user to the Administrators group so that, after you log in as the secondary user, you can reset your main account's password.
