Blocking command line pushes that expose your personal email address

When you push commits from the command line, the email address that you've set in Git is associated with your commits. If you enable this setting, each time you push to GitHub, we’ll check the most recent commit. If the author email on that commit is a private email on your GitHub account, we will block the push and warn you about exposing your private email.

For more information on commit email addresses, including your GitHub-provided noreply email address, see "Setting your commit email address."

1. In the upper-right corner of any page, click your profile photo, then click Settings.
2. In the left sidebar, click Emails.
3. To keep your email address private when performing web-based Git operations, click Keep my email addresses private.
4. To keep your email address private in commits you push from the command line, select Block command line pushes that expose my email.
