It is necessary to make authorization through social networks without a redirect, but by calling the javascript callback function, passing parameters to it. So far I've done this:

public function actions()
{
    return [
        'auth' => [
            'class' => 'yii\authclient\AuthAction',
            'successCallback' => function ($client) {
                $provider = $client->id;
                $userAttributes = $client->userAttributes;
                Yii::$app->response->format = Response::FORMAT_JSON;
                Yii::$app->response->data = [
                    'provider' => $provider,
                    // ...
                ];
            },
        ],
    ];
}

As a result, after authorization, json data is displayed in the open popup window. What to do next?

Look at the source, everything is simple there. If my memory serves me, then the redirect is just performed through js
window.location =...
