Respond to Captcha-Authentication #9
Description
Occasionally authentication may fail if google responds with a captcha request instead of an auth token. This can be handled programmatically but has not been implemented. A user would be presented with a url to visit to be solve the captcha. A better solution would be to implement oauth which should seamlessly integrate into the client class as long as the client interface is maintained. There is limited documentation on google about supporting the pin method of oauth which would involve presenting the user with a url to visit and showing them a pin number to enter in the app. The documentation seems to prefer redirecting the user to a domain owned by the project and registered with google.
