Password of the root user in ubuntu live cd

Do you need the root password of ubuntu live cd?.
One thing you do.You can reset it by applying command in the terminal

# sudo passwd root
Then it will prompt password then you can give the new password
(note:- though it is live cd, the password will not be permanent. So you have to reset by using above command at each time)
