 ## Scope
 
-The Working Group will specify new web platform features intended to be
-implemented in browsers or similar user agents. The purpose of these
-features is to support authentication and authorization flows without
-compromising security principles for IdPs, RPs, and user agents as well
-as user privacy. Here \"privacy\" minimally refers to the appropriate
-processing of personal information. The result of this work is the
-development of new mechanisms that define how information is passed by the
-browser between the RP and the IdP to facilitate federated
-authentication; it is not an authentication method.

-If any of the mechanisms developed to support authentication and authorization flows looks like it will result in breaking changes for existing protocols, work on that mechanism must include a well-documented transition period.
