PyCharm exposed password via Git

I installed Git and started using it without creating a config file.  I noticed that PyCharm supplied my network password in lieu of the email address for both the Author and Committer fields.  

Adding a config file solved that problem.  When identifying the user and email, it picks up on that instead.  

Now, if anyone can tell me how to edit a Git commit object, I would appreciate the info.

This happened again when starting another project.  It seems that the config file should be created automatically.   Defaulting to a password as contact information doesn't make sense.
