Grandfather can't remember his password

[DVDSP]

My wife's grandfather can't remember is password. He recently decided to rejoin AOL (don't ask me why) but can't install their software for two reasons:

1) His OS is out of date (He needs 10.4.8 and has 10.4.2) and

2) without an Internet connection OR password he can't update the OS OR install AOL.

I seem to remember there was a way to use the terminal to find his admin password. I could be very wrong.

The only other solution I can this is to back up all his stuff (there isn't much), wipe his HD and reinstall Tiger from scratch. I brought his mini home with me so I have everything I need to do that, but I'd rather not.

Any suggestions appreciated,

I believe that if you boot from the install disks you can reset the password.

Yup

That worked, I've reset the password and am upgrading him to 10.4.11 now.

Thanks,
