 Once you have a user instance, you can grab a few more details about the user:
 
 ```php
-$user = Socialite::driver('katsana')->user();
+$passport = Socialite::driver('katsana')->user();
 
 // OAuth Two Providers
-$token = $user->token;
-$refreshToken = $user->refreshToken; // not always provided

 #### Retrieving User Details From Token
 
 If you already have a valid access token for a user, you can retrieve their details using the `userFromToken` method:
 
 ```php
-$user = Socialite::driver('katsana')->userFromToken($token);
+$passport = Socialite::driver('katsana')->userFromToken($token);
 ```
