They won't be able to give you your current password, since (like XP) only it's computed hash value is ever stored, but they can give you a new password.
I have an XP, SP2 computer with a dial-up internet connection. My user name and password are remembered so I don't have to enter them when connecting. I want to use the same connection on another computer, an old Mac Power PC. I know my user name but not my password. (I've got it written down somewhere but recently moved and haven't found it yet, along with many other things!)
Is there any way to find my password that XP stores or should I just contact my ISP?
