EAuth extension allows to authenticate users with accounts on other websites. Supported protocols: OpenID, OAuth 1.0 and OAuth 2.0.
EAuth is a extension for provide a unified (does not depend on the selected service) method to authenticate the user. So, the extension itself does not perform login, does not register the user and does not bind the user accounts from different providers.
The implementation of the authorization on your own server has several advantages:
- Full control over the process: what will be written in the authorization window, what data we get, etc.
- Ability to change the appearance of the widget.
- When logging via OAuth is possible to invoke methods on API.
- Fewer dependencies on third-party services - more reliable application.
- Ignore the nuances of authorization through the different types of services, use the class based adapters for each service.
- Get a unique user ID that can be used to register user in your application.
- Extend the standard authorization classes to obtain additional data about the user.
- Work with the API of social networks by extending the authorization classes.
- Set up a list of supported services, customize the appearance of the widget, use the popup window without closing your application.
- The component that contains utility functions.
- A widget that displays a list of services in the form of icons and allowing authorization in the popup window.
- Base classes to create your own services.
- Ready for authenticate via Google, Twitter, Facebook and other providers.

?>To receive all the necessary data to your application, you can override the base class of any provider.
Base classes are stored in protected/extensions/eauth/services/.
Examples of extended classes can be found in protected/extensions/eauth/custom_services/.
After overriding the base class, you need to modify your configuration file to set new name of the class.
Also you may need to override the EAuthUserIdentity class to store additional data.
- Copy the file
/protected/extensions/eauth/messages/[lang]/eauth.phpto/protected/messages/[lang]/eauth.phpto translate the EAuth extension into other languages. - To add a new language, you can use the blank file
/protected/extensions/eauth/messages/blank/eauth.php.
Some time ago I developed this extension for LiStick.ru and I still support the extension.
The extension was released under the New BSD License, so you'll find the latest version on GitHub.
