Yes! If you have a Google account and haven't already registered this email within the app, you can register for Handouts via the Google Account Login (underneath the large green 'Login' button).
Don't forget! if you already used your Google email address to register for Handouts via the normal registration process, you won't be able to use the same email address to create another Handouts account via Google Account Login. You can either contact us to request that your Handouts account be deleted so that you can re-register via Google Account Login, or create a new Gmail account when prompted.
Write to us at firstname.lastname@example.org any time you have questions!
