Managing email preferences
You can add or change the email addresses associated with your account. You can also manage emails you receive from GitHub.
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
To change your primary email address, you'll add a new email, then delete the old one.
Setting a backup email address
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.
Setting your commit email address
You can set the email address that is used to author commits on GitHub and on your computer.
