What is root?
Root is the name of the most powerful account on a Debian installation. The root user account can do everything on the machine. Root is also known as supervisor and administrator. Root's home (~) folder is /root.
At installation time, you are asked whether you want to use the root account or not.
if you want to (the default), you'll be asked to provide a complex password for root. Use a strong one!
if not, no root account is enabled and the password of the first user created will be used for administration tasks.
If you forgot your password, read [http://www.debian.org/doc/manuals/reference/ch-tips#s-crackroot "I forgot the root password!"]
