Get salt to add to hashes.
Salts are created using secret keys. Secret keys are located in two places: in the database and in the wp-config.php file. The secret key in the database is randomly generated and will be appended to the secret keys in wp-config.php.
The secret keys in wp-config.php should be updated to strong, random keys to maximize security. Below is an example of how the secret key constants are defined. Do not paste this example directly into wp-config.php. Instead, have a {@link https://api.wordpress.org/secret-key/1.1/salt/ secret key created} just for you.
define('AUTH_KEY', ' XakmM%G4Yt>f`z]MON');
define('SECURE_AUTH_KEY', 'LzJ}op]mr|6+![P}Ak:uNdJCJZd>(Hx.-Mh#Tz)pCIU#uGEnfFz|f ;;eU%/U^O~');
define('LOGGED_IN_KEY', '|i|Ux`9z7X>QYR0Z_XnZ@|');

define('SECURE_AUTH_SALT', '!=oLUTXh,QW=H `}`L|9/^4-3 STz},T(w}W*c(u`g~EJBf#8u#R{mUEZrozmm');
define('NONCE_SALT', 'h`GXHhD>SLWVfg1(1(N{;.V!MoE(SfbA_ksP@&`+AycHcAV$+?@3q+rxV{%^VyKT');
Salting passwords helps against tools which has stored hashed values of common dictionary strings. The added values makes it harder to crack.
