Newb starting MySql-Permissions

[marko2]

I have debian running and this is how I have it setup

# ls -ld /var/lib/mysql
drwxr-xr-x 4 mysql mysql 4096 Aug 19 11:29 /var/lib/mysql

I was shown how to setup a password for user mysql here
http://dle.ascendant.ca/restoring-mysql-root-HOWTO.txt,

because at one time all I would have to do it hit enter after
# mysql -h localhost -p -u mysql
Enter password: (no password is added I just hit enter)
Welcome to the MySQL monitor. Commands end with ; or \g.

mysql> ( can do whatever I want now???)
If I type in the correct password it lets me in, if I type in no passowrd it
lets me in, if I type in the INCORRECT password it does NOT let me in. How
can I make it so that if no password is typed it still treats it as
incorrect???

Also when I type just any username (asdfasdf) for the help of it and the hit
enter as the password it still just lets me in.... Sorry if this is basic to
some but the mysql.org site only deals with getting people connected not if
they notice stuff like this.
