Quite the title and quite cool to use. The Hybrid Protocol combines OpenID and OAuth in such a way that with one flow you can ask for authentication (and get someones account information, like name and email) and authorization (a token) for a set of services specified in a scope.

Apart from providing a much cleaner user experience, it’ll save you a bunch of code. Especially via Omniauth.

I’ve created ~~a fork~~ (read update) that contains the google_hybrid strategy and an example project that implements it.

UPDATE: My strategy just got merged into Omniauth’s master branch. So just use Omniauth instead of my fork.

To see how it works, try this demo.
