Am a newbie to webroot and ask how to pass word protect my WR settings account?

Hello to all webroot users
I am new to the webroot internet security apps. and the forumns and would like to secure my
WR internet security account, with a password protected account before any would be hacker
might see that it's not yet pass word protected. How do I assign a pass word settings account
for my Web Root Security?
I previously had a Norton Internet Security  account that I never assigned a PW for settings
changes, and was hacked, and a hacker took advantage by filing for himself a pass word
which locked me out.
Thanks for any help.
