Password Hash is a WordpPress plugin that improves the WordPress password hashing security by using the builtin <a href="http://php.net/manual/en/function.password-hash.php" rel="nofollow ugc"><code>password_hash</code></a> and <a href="http://php.net/manual/en/function.password-verify.php" rel="nofollow ugc"><code>password_verify</code></a> functions.
If the installed PHP version doesn’t support those methods, it falls back to the standard PHPass method.

Password Hash

Replaces wp_hash_password and wp_check_password with PHP password_hash and password_verify if PHP has support for them.
