You cannot access personal data via the Google API without the OAuth-2 authentication and both components does not support that. The authentication methods from the components does not containing OAuth authentication and I am not sure if it make sense to add that very complex mechanism to this both basic components.
I've written a tutorial on using OAuth 2.0 with Google's products here. It makes use of the refresh tokens and *should* be able to be extrapolated from for use with other products using OAuth 2.0. I hope it helps
