Access_token too short ~ jwt malformed

@anny So, if someone has the acces token that’s a string (not a JWT), here are some simple yes/no questions, supposing when does a call to /authorize and an audience https://YOUR_DOMAIN.auth0.com/userinfo (and default response types), and using RS256:

  1. one can a call the /userinfo endpoint?
  2. that call returns a result if the access token is set as Bearer in the Authorization header
  3. if the call returns the user info, can I assume that it means that the user is authenticated properly? (So, instead of validating a JWT, on could do a call to /userinfo to validate the access token and get some claims about the user (like email etc)?)
