yup-oauth2 1.0.8

An oauth2 implementation, providing the 'device', 'service account' and 'installed' authorization flows

Build Status Coverage Status crates.io

yup-oauth2 is a utility library which implements several OAuth 2.0 flows. It's mainly used by google-apis-rs, to authenticate against Google services. (However, you're able to use it with raw HTTP requests as well; the flows are implemented as token sources yielding HTTP Bearer tokens).

Supported authorization types

  • Device flow (user enters code on authorization page)
  • Installed application flow (user visits URL, copies code to application, application uses code to obtain token). Used for services like GMail, Drive, ...
  • Service account flow: Non-interactive for server-to-server communication based on public key cryptography. Used for services like Cloud Pubsub, Cloud Storage, ...


Please have a look at the API landing page for all the examples you will ever need.

A simple commandline program which authenticates any scope and prints token information can be found in the examples directory.

The video below shows the auth example in action. It's meant to be used as utility to record all server communication and improve protocol compliance.
