About

OAuth is an open standard authorization protocol that allows applications to obtain limited access to user accounts without sharing passwords across web, mobile, and desktop environments.

It uses token-based authorization with access and refresh tokens, lets users grant specific permissions to applications such as access to profile data or contacts, and is widely adopted by online service providers such as Google, Facebook, Microsoft, and GitHub.

Really Simple Discovery (RSD) is an XML format that helps client software find the services needed to read, edit, or "work with" weblogging software.
