## 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).
