## Current Features

### Authorization Server

The authorization server is a flexible class and the following core specification grants are implemented:

* authorization code ([section 4.1](http://tools.ietf.org/html/rfc6749#section-4.1))
* refresh token ([section 6](http://tools.ietf.org/html/rfc6749#section-6))
* client credentials ([section 2.3.1](http://tools.ietf.org/html/rfc6749#section-2.3.1))
* password (user credentials) ([section 4.3](http://tools.ietf.org/html/rfc6749#section-4.3))

An overview of the different OAuth 2.0 grants can be found in the wiki [https://github.com/php-loep/oauth2-server/wiki/Which-OAuth-2.0-grant-should-I-use%3F](https://github.com/php-loep/oauth2-server/wiki/Which-OAuth-2.0-grant-should-I-use%3F).

### Resource Server

The resource server allows you to secure your API endpoints by checking for a valid OAuth access token in the request and ensuring the token has the correct scope(s) (i.e. permissions) to access resources.

### Custom grants

Custom grants can be created easily by implementing an interface. Check out a guide here [https://github.com/php-loep/oauth2-server/wiki/Creating-custom-grants](https://github.com/php-loep/oauth2-server/wiki/Creating-custom-grants).

### PDO driver

If you are using MySQL and want to very quickly implement the library then all of the storage interfaces have been implemented with PDO classes. Check out the guide here [https://github.com/php-loep/oauth2-server/wiki/Using-the-PDO-storage-classes](https://github.com/php-loep/oauth2-server/wiki/Using-the-PDO-storage-classes).
