GitHub Enterprise Server 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."
You can change the email address associated with your personal account at any time.
Use a backup email address as an additional destination for security-relevant account notifications and to securely reset your password if you can no longer access your primary email address.
You can set the email address that is used to author commits on your GitHub Enterprise Server instance and on your computer.
