## Description

GDataGoaAuthorizer provides an implementation of the GDataAuthorizer interface for authentication and authorization using GNOME Online Accounts (GOA) over D-Bus. This allows a single login session (managed by the GOA daemon) to be used by multiple applications simultaneously, without each of those applications having to go through the authentication process themselves. Applications making use of GDataGoaAuthorizer don't get access to the user's password (it's handled solely by the GOA daemon).

Internally, GOA authenticates with the Google servers using the OAuth 1.0 process.

GDataGoaAuthorizer natively supports authorization against multiple services (unlike GDataClientLoginAuthorizer), depending entirely on which services the user has enabled for their Google account in GOA. GDataGoaAuthorizer cannot authenticate for more services than are enabled in GOA.
