How to change my Git username in terminal?

1. In your terminal, navigate to the repo you want to make the changes in.
2. Execute git config --list to check current username & email in your local repo.
3. Change username & email as desired. Make it a global change or specific to the local repo:
   git config [--global] --replace-all user.name "Full Name"
git config [--global] --replace-all user.email "email@address.com"
   
   Per repo basis you could also edit .gitconfig manually instead.
4. Done!

You probably need to update the remote URL since github puts your username in it. You can take a look at the original URL by typing

git config --get remote.origin.url

Or just go to the repository page on Github and get the new URL. Then use

git remote set-url origin https://{new url with username replaced}

to update the URL with your new username.

1. EDIT: In addition to changing your name and email You may also need to change your credentials:

• To change locally for just one repository, enter in terminal, from within the repository

  git config credential.username "new_username"

• To change globally use

  git config --global credential.username "new_username"

  (EDIT EXPLAINED: If you don't change also the user.email and user.name, you will be able to push your changes, but they will be registered in git under the previous user)

2. Next time you push, you will be asked to enter your password

   Password for 'https://<new_username>@github.com':
