title: All possible scope options in Passport for Facebook and Google
body: <p>I am unable to locate all possible scope options in passport for facebook and google.
  Could anyone mention all possible scope option/values that we could pass during authentication for facebook and google?</p>
  
  <p>I need to use other scope options for facebook and google just like I am currently using 'email' scope values. Please mention all possible scope options for facebook and google seperately.</p>
  
  <pre><code>passport.authenticate(key, {scope: ['email']})(req, res, next);
  </code></pre>
