WordPress Security Keys

In WordPress 2.8 there are four  (4) security keys , AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY, and NONCE_KEY that you can optionally add to your wp-config.php file to ensure better encryption of information stored in the user’s cookies. You can use the online generator to automatically generate random keys for your WordPress install…see the default wp-config-sample.php file for the url to the online generator.

An example of keys from the online generator:

These keys are optional, but including them will enhance the security of your WordPress site. In simple terms, a secret key is a password with elements that make it harder to generate enough options to break through your security barriers, so since they are free, easy to generate, you only have to add them one time, and you never have to remember them, no site should be without them. Do you have these in your wp-config.php file?
