Complex WordPress Security Keys
WordPress makes use of a set of long, random and complex Security Keys. These keys consist of a number of encryption keys as well as cryptographic salts.
Security Keys ensure better encryption of information stored in the users’ cookies. There are a total of eight security keys that WordPress uses – AUTH_KEY, SECURE_AUTH_KEY, LOGGED_IN_KEY, NONCE_KEY, AUTH_SALT, SECURE_AUTH_SALT, LOGGED_IN_SALT, and NONCE_SALT.
A Security Key functions similarly to a very strong password or passphrase and should contain elements that make it harder to generate enough options to crack. WordPress Security Keys also make use of cryptographic salts to further strengthen the security of the generated result.
You can either make your own random keys, or you can use WordPress’ online key generator to do this for you. Simply copy and paste the keys generated by the generator into your wp-config.php file.
