The CSS comes from wp-includes/css/buttons.css. Do not change this this file; it will be overridden during the next update. Create a separate plugin instead, or add some custom code to your theme’s functions.php, and hook into login_head:

add_action( 'login_head', function() {
.button {
    background: red !important;

enter image description here
