GitHub uses the email address in the commit header to link the commit to a GitHub user. If your commits are being linked to another user, or not linked to a user at all, you may need to change your local Git configuration settings, add an email address to your account email settings, or do both.

Note: If your commits are linked to another user, that does not mean the user can access your repository. A user can only access a repository you own if you add them as a collaborator or add them to a team that has access to the repository.

Commits are linked to another user

If your commits are linked to another user, that means the user has added the email address in your local Git configuration settings to their GitHub account. In this case, you can change the email in your local Git configuration settings and add the new email address to your GitHub account to link future commits to your account.

  1. To change the email address in your local Git configuration, follow the steps in "Setting your email in Git". If you work on multiple machines, you will need to change this setting on each one.
  2. Add the email address from step 2 to your account settings by following the steps in "Adding an email address to your GitHub account".

Commits you make from this point forward will be linked to your account.

Commits are not linked to any user

If your commits are not linked to any user, we will display the grey Octocat logo beside them:

To check the email address used for those commits and connect commits to your account, take the following steps:

  1. Navigate to the commit by clicking the commit message link. Commit message link
  2. To read a message about why the commit is not linked, hover over the blue to the right of the username. Commit hover message

If your local Git configuration contained a generic email address, or an email address that was already attached to another user's account, then your previous commits will not be linked to your account. While Git does allow you to change the email address used for previous commits, we strongly discourage this, especially in a shared repository. See "Changing author info" for more information.
