Hi Hive account@gokulnk, I just released a Drupal module, a PHP library and a Wordpress plugin :)

I've posted an article with all the information there : https://steemit.com/drupal/@guix77/do-you-want-steem-users-to-login-to-your-drupal-wordpress-or-other-php-site

Thank you for the initial idea, it was a very interesting project :)
