Hi Jason M,
Sitefinity is using either Windows or Forms authentication, so without appropriate authentication you won't be able to gain access to the restricted Sitefinity pages. And as far as I know Google Mini doesn't support Forms Authentication.
A possible workaround would be to create a custom HttpModule which runs prior the Sitefinity's HttpModule and perform a check wherever the request is from Google Mini, and Authenticate it.
Beware that such implementation could lead to security risk, so proceed with caution.
