Convert Twitter Basic Authentication to OAuth Credentials

Prior Steps:

  1. Register an application with Twitter and note the Consumer Key/Secret.
  2. Configure the application to be of Application Type "Browser" and use http://danzambonini.com/convert-to-oauth/ as the Callback URL (you can change this back later)
  3. Log In as the Twitter User whose credentials you want to use.
  4. Come back here and enter the application key/secret
