Adding an email address to your GitHub account→
GitHub allows you to add as many email addresses to your account as you like. If you set an email address in your local Git configuration, you will need to add it to your account settings in order to connect your commits to your account. For more information about your email address and commits, see "Setting your commit email address."
Changing your primary email address→
You can change the email address associated with your user account at any time.
Setting a backup email address→
Use a backup email address to securely reset your password if you can no longer access your primary email address.
Setting your commit email address→
You can set a primary email address on GitHub that's associated with web-based Git operations you perform such as edits and merges.
Blocking command line pushes that expose your personal email address→
If you've chosen to keep your email address private when performing web-based operations, you can also choose to block command line pushes that may expose your personal email address.
