Authentication is split into four parts:

  1. Authentication mechanisms

  2. Password schemes

  3. Password databases

  4. User databases

== Authentication mechanisms vs. password schemes == Authentication mechanisms and password schemes are often confused, because they have somewhat similar values. For example there is a PLAIN auth mechanism and PLAIN password scheme. But they mean completely different things.
