title: What exactly is an "OAuth Provider"?
body: <p>I want to understand what is usually meant by the term &quot;OAuth Provider&quot;. There seems no mention of it in the <a href="https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-25" rel="nofollow noreferrer">OAuth specification</a>.</p>
  <p>If we consider a OAuth Provider as a component of an application, what functions does it perform (e.g. authorization, implementation of API methods, etc.)? How does it relate to the rest of the application?</p>
