Good evening. I am new to wordpress and checking out my options for a CMS. From what I understand about the Authentication Unique Key, it's to prevent hacker intrusions.
I have read http://codex.wordpress.org/Editing_wp-config.php
What exactly are they hacking into? I mean, what is the this authentication protecting?
I figure I better understand some level of security...
Thanks for the simple (relatively) explanation.
