Hi, I had my Powerbook in for service recently. Since they'd asked for my account password, I decided to change it once I got my Powerbook back. Well to make a long story short, after changing it I accidentally typed my old password - and it still worked (as did the new one). I can use both to log in, to unlock the screen after sleep, to get at my keychain... So I decided to try changing it a third time. The new password works, and the ORIGINAL password still works! Password #2 does NOT work. I did a search of Apples knowledgebase which turned up one article that had a heading which seemed like it should answer my question, but the actual article was totally irrelevant (it was talking about root versus administrator accounts). I am currently running Panther 10.3.1, with the root account disabled as per the default. I don't have a master password set, and I'm not using filevault. Thanks to anyone who can shed light on this!!
