Recovering the password is difficult or impossible, but also unnecessary; root can reset a user's password. To find the user name, cat /etc/passwd. Look for a familiar user name near the end of that file, then use the passwd utility (as root) to reset the password fot that user name. Be careful to select only the username you are actually looking for; there are many others in /etc/passwd, and you probably want to leave those alone. See cat and passwd manual pages; "man cat" and "man passwd". It's practically a mantra of mine: man is your friend.
