Authentication and Authorization
Flux uses OpenID Connect integrated with OAuth 2.0 for authentication and authorization.
This is a multi-step process with a few different variations, such as the "server" flow (e.g., for Node servers) and the "implicit" flow (e.g., for web apps).
We recommend Google's guides on OpenID Connect and OAuth 2.0 for more information on the details.
The JavaScript SDK provides helper methods to simplify the authentication/authorization process: #getAuthorizationUrl and #exchangeCredentials.
