2. Fill out the following pre-review checklist:

   • [ ] I am adding a new automated test(s) to verify correctness of my new code
   • [x] I am adding new logging messages
   • [ ] I am adding a new telemetry message
   • [ ] I am modifying authorization mechanisms

3. Please describe how your code solves the related issue.

   The use of print breaks piping outputs, as the output is contaminated with the message when using exteranlbrowswer authentication. Moving these messages into logging allows for pipelining, and also elevating the the failure mode to a more suitable level of urgency.
