My purpose here is to try and teach myself a little bit of oAuth integration using Twitter as a auth mechanism for Flaskr. I'm going to use Tweepy as my oAuth wrapper. Originally I chose not to implement the callback and went with a manual verifier. After some investigation I determined that I could use a "localhost" callback url. So I did. The part that still flummoxes me is the authorization/authentication. Each auth includes an explicit authorization of the app. It would seem to me that you should only have to authorize an app once, and then login/authentication going forward. I moved my consumer keys and other specific things to a settings_local.py that I did not submit to git hub.
