When 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.
- In the upper-right corner of any page on GitHub, click your profile picture, then click Settings.
- In the "Access" section of the sidebar, click Emails.
- To keep your email address private when performing web-based Git operations, select Keep my email addresses private.
- To keep your email address private in commits you push from the command line, select Block command line pushes that expose my email.
