title: Does Oauth 2.0 need consumer key/consumer secret
body: <p>So evidently when using OAuth 1.0 you need to acquire consumer key and consumer secret from the API provider...</p>
  
  <p>But then when I try to use OAuth 2.0 APIs such as Facebook, Google Oauth 2.0, etc I never needed to acquire consumer key/consumer secret (I acquired App ID and App secret for Facebook, but those are different from consumer key/consumer secret am I correct?)</p>
  
  <p>So my question is...is it true that when using Oauth 2.0, you don't need to have a consumer key/consumer secret as in Oauth 1.0</p>
  
  <p>Also there are no signature methods (HMAC-SHA1 etc) necessary for Oauth 2.0, is that correct? HMAC-SHA1 is only relevant for Oauth 1.0, correct? </p>
