Laravel Auth::atempt keeps failing - oauth

Question

I am using this code to authenticate user with Facebook and laravel-oauth2 package. But my Auth::atempt keeps failing.(Ecos FLAG) Can someone help me see the problem ? Here is my controller function and code for my route:
Route::get('oauth/{provider}', 'HomeController#provide');
public function provide($provider)
{
$init_p = $provider;
$provider = OAuth2::provider($provider, array(
'id' => 'MY ID',
'secret' => 'MY SECRET',
));
if ( ! isset($_GET['code']))
{
return $provider->authorize();
}
else
{
try
{
$params = $provider->access($_GET['code']);
$token = new Token_Access(array(
'access_token' => $params->access_token
));
$provided_user = $provider->get_user_info($token);
if($init_p == 'facebook')
{
if (User::whereFacebookUid($provided_user['uid'])->first())
{
if(Auth::check())
{
return Redirect::to('/testovi');
}
else
{
if (Auth::attempt(array('password' => $provided_user['uid'])))
{
return Redirect::to('/testovi');
}
else
{
echo("FLAG");
}
}
}
else
{
$user = new User;
$user->name = $provided_user['name'];
$user->email = $provided_user['email'];
$user->password = $provided_user['uid'];
$user->facebook_uid = $provided_user['uid'];
$user->save();
Auth::login($user);
return Redirect::to('testovi');
}
}
}
catch (OAuth2_Exception $e)
{
show_error('That didnt work: '.$e);
}
}
}

Solution was to HASH uid befor saving id to db. Details from:
Details
$user = new User;
$user->username = $provided_user['name'];
$user->email = $provided_user['email'];
$user->password = Hash::make($provided_user['uid']);
$user->facebook_uid = $provided_user['uid'];
$user->save();
Auth::login($user);
return Redirect::to('testovi');
