WordPress Auth Salt is a cryptographic element that adds an extra layer of randomness to the way WordPress secures login sessions and stored authentication data. When users log in, their credentials are hashed and stored in cookies. Without salts, these hashes could be more easily guessed or cracked through brute-force attacks. By introducing unique, unpredictable values, the Auth Salt ensures that even if two users have the same password, their authentication data will still be different. This significantly reduces the risk of cookie hijacking, session theft, and unauthorized access, making it an essential component of WordPress security.
WordPress salts are special security keys used to protect the login and authentication process in WordPress. They are:
In the wp-config.php file of your WordPress installation, you’ll find lines like:
define('AUTH_KEY', 'random-characters-here'); define('SECURE_AUTH_KEY', 'random-characters-here'); define('LOGGED_IN_KEY', 'random-characters-here'); define('NONCE_KEY', 'random-characters-here'); define('AUTH_SALT', 'random-characters-here'); define('SECURE_AUTH_SALT', 'random-characters-here'); define('LOGGED_IN_SALT', 'random-characters-here'); define('NONCE_SALT', 'random-characters-here');
