Identity: Change GIT author id and email

Posted on December 23, 2015 Updated on December 23, 2015

Did you want to use a different author name and email then the default one GIT has for you?

Change Authorname:
git config --global user.name "New Authorname"

Change email:
git config --global user.email username@domain.com

“you need to do this only once if you pass the --global option, because then Git will always use that information for anything you do on that system. If you want to override this with a different name or email address for specific projects, you can run the command without the --global option when you’re in that project.”
