you can change "main.py" to "main-private.py" in file app.yaml for private using.
1,you MUST set USER_PASSWORD in main-private.py for your gtap and DO NOT share it with anyone.
2,find these variables of your application from https://dev.twitter.com/apps/ and modify them in main-private.py CONSUMER_KEY = Consumer key CONSUMER_SECRET = Consumer secret ACCESS_TOKEN = Access token ACCESS_TOKEN_SECRET = Access token secret
*if you can not find "Access token" and "Access token secret", click the "Create my access token" button.
3,now you can use gtap via USER_PASSWORD(and any username) without any oauth-authorization
