if ( $GLOBALS['pagenow'] === 'wp-login.php' && ! empty( $_REQUEST['action'] ) && $_REQUEST['action'] === 'register' ) {

 field to my form:

//Add Custom Password Field
        $output .= '<div class="col-md-12 col-lg-12 col-sm-12 col-xs-12">';
        $output .='<label class="password">';

        $cs_opt_array = array(
            'id' => '',
            'std' => __('Password', 'jobhunt'),
            'cust_id' => 'user_pass' . $rand_id,

            'extra_atr' => ' size="100" tabindex="101" placeholder="' . __('Password*', 'jobhunt') . '"',
            'return' => true,


        );
        $output .= $cs_form_fields2->cs_form_text_render($cs_opt_array);

        $output .='</label>';

        $output .= '</div>';
        $output .= '<div class="col-md-12 col-lg-12 col-sm-12 col-xs-12">';

            'cust_id' => 'user_pass' . $rand_id,

        $output .= $cs_form_fields2->cs_form_text_render($cs_opt_array);

        $output .='</label>';
        $output .= '</div>';
        //End
After that i validate this two fields by below code:

 if ( empty( $_POST['pass1'] ) || ! empty( $_POST['pass1'] ) && trim( $_POST['pass1'] ) == '' ) {
        $json['type'] = "error";
        $json['message'] = $cs_danger_html . __('<strong>ERROR</strong>: Password field is required.') . $cs_msg_html;
        echo json_encode($json);
        exit();
        }
        if ( empty( $_POST['pass2'] ) || ! empty( $_POST['pass2'] ) && trim( $_POST['pass2'] ) == '' ) {
         $json['type'] = "error";
         $json['message'] = $cs_danger_html . __('<strong>ERROR</strong>: Confirm Password field is required.') . $cs_msg_html;
         echo json_encode($json);
         exit();
        }
        if ( $_POST['pass1'] != $_POST['pass2'] ) {
            $json['type'] = "error";
            $json['message'] = $cs_danger_html . __('<strong>ERROR</strong>: Password field and Confirm Password field do not match.') . $cs_msg_html;
            echo json_encode($json);
            exit();
        }

    $random_password = $_POST['pass1'];
After validation its time to save the data in database and i used below code for saving the entered password:

function mytheme_registration_save($user_id) {


if ( isset($_REQUEST['action']) && $_REQUEST['action'] == 'register' ) {

    $random_password = $_POST['pass1'];
    wp_set_password($random_password, $user_id);
    $reg_user = get_user_by('ID', $user_id);
    if ( isset($reg_user->roles) && (in_array('subscriber', $reg_user->roles) || in_array('editor', $reg_user->roles) || in_array('author', $reg_user->roles)) ) {
        // Site owner email hook
        do_action('theme_domain_new_user_notification_site_owner', $reg_user->data->user_login, $reg_user->data->user_email);
        // normal user email hook
        do_action('theme_domain_user_register', $reg_user, $random_password);
    }
}
}
}
