A standards compliant [OAuth 2.0](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-v2/) authorization server and resource server written in PHP which makes working with OAuth 2.0 trivial.

* Resource owner password credentials grant
* Refresh grant

You can also define your own grants.

In addition it supports the following token types:

* Bearer tokens
* MAC tokens (coming soon)
* JSON web tokens (coming soon)

* PHP 5.4
* PHP 5.5
