title: what is the difference between openam and openid SSO implementation?
body: <p>As far as my understanding goes, OpenID uses accounts made on other websites to sign in to the website, so that user won't have to create multiple username and password.</p>
  
  <p>Does OPENAM not to do the same thing? It uses providers like Facebook google in order to authenticate the user.</p>
  
  <p>Please correct me if I am wrong.</p>
