Drupal 7 user authorization from ionic 3

Hi All

I am trying to access Drupal (CMS) and Civicrm (CRM) from Ionic 3 Mobile application - using same login page

So, I am trying to login to Drupal - Using BaseUrl, username and Password - Is this possible without installing any modules against Drupal?

If so Please let me know how to achieve the same - Even if you have any sample project that would be great

If this is not Possible then what would be the alternative to do so ?

Thanks in advance
