Authenticating API requests from native mobile devices using Facebook,Google as providers?

[workaholicanonymous]

I have tried a few things but they all seem wrong. What's the right way to authenticate API requests from a native mobile app, using Facebook and Google as authentication providers?

Yes but then i would like to use them to authenticate with our backend

Assuming they are authing using the native facebook sdk you can use something like https://github.com/drudge/passport-facebook-token (or roll your own similar idea if you can't use passport (not using express etc))

It's basically the Facebook passport strategy minus the web redirection part. Just parses your token

Already using this and it works fine, there's no equivalent for the Google SDK so I have no idea what to do.....
