I would recommend that you rethink/refactor your authentication choices.<p>From a usability perspective it is kind of a pain to be required to login with two separate accounts to use a service.<p>I recommend that instead of using google accounts at all, you just use the oauth authentication api from DropBox: <a href="https://www.dropbox.com/developers/start/authentication#python" rel="nofollow">https://www.dropbox.com/developers/start/authentication#pyth...</a><p>You should be able to achieve the same thing you're doing now with google+dropbox with just dropbox.
