What is "well known" file associated with ``gcloud`` command line tool

Question

In some gcloud code I'm finding a comment:

Stored "well known" file associated with gcloud command line tool

What is this "well known" file?

Answer 1

I believe this is what you're looking for: https://github.com/google/oauth2client/blob/master/oauth2client/client.py#L1367

For Linux/MacOSX, it's ~/.config/gcloud/application_default_credentials.json
