Simple password grants with OAuth 2.0 and Drupal

Like many Drupal developers, we have become big fans of decoupled front-ends using Drupal as a RESTful backend (a.k.a. "headless" Drupal). The myriad of authorization options can be confusing, however. We've settled on OAuth 2.0 for most situations. When OAuth is brought up, many people will think of the single-sign-on flow in a browser, with the associated redirects and permission dialogs. This flow is widely used, but not always a good fit for first-party applications, or machine-to-machine API interactions.

Drupal 7 Form API: Using #states with multiple conditionals (AND, OR and XOR)
