OAuth (Open Authorization) is an open protocol to allow secure API authorization in a simple and standardized way from desktop and web applications. The Force.com platform implements the OAuth 2.0 Authorization Framework, so users can authorize applications to access Force.com resources (via the Force.com REST and SOAP Web Service APIs) or Chatter resources (via the Chatter REST API) on their behalf without revealing their passwords or other credentials to those applications. Alternatively, applications can directly authenticate to access the same resources without the presence of an end user.
