Securing WordPress Login: Hiding Error Messages

This code snippet enhances the security of your WordPress site by hiding specific login error messages. Normally, WordPress displays errors that can give hints about whether a username is correct or not, which could be used for malicious attempts. By customizing the error message to a generic response, this snippet helps prevent such security vulnerabilities

add_filter( 'login_errors', 'snn_hide_login_errors' );
function snn_hide_login_errors( $error ) {
    // Edit the line below to customize the message.
    return 'Something is wrong!'; // You can customize this message as needed
}
