Inheritance	yii\authclient\clients\Facebook » yii\authclient\OAuth2 » yii\authclient\BaseOAuth » yii\authclient\BaseClient » yii\base\Component » yii\base\BaseObject
Implements	yii\authclient\ClientInterface, yii\base\Configurable
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2-authclient/blob/master/clients/Facebook.php

Facebook allows authentication via Facebook OAuth.

In order to use Facebook OAuth you must register your application at https://developers.facebook.com/apps. Add an app. In "Settings" -> "Basic" specify "App Domains". There you can obtain ID and Secret values to put into config. In "Products" press "+" and add "Facebook Login". In its settings make sure you enabled "Web OAuth Login" and specify "Valid OAuth Redirect URIs" as "https://example.com/auth?authclient=facebook".

Example application configuration:

'components' => [
    'authClientCollection' => [
        'class' => 'yii\authclient\Collection',
        'clients' => [
            'facebook' => [
                'class' => 'yii\authclient\clients\Facebook',
                'clientId' => 'facebook_client_id',
                'clientSecret' => 'facebook_client_secret',
            ],
        ],
    ]
    // ...
]
