### Required co-author information
Before you can add a co-author to a commit, you must know the appropriate email to use for each co-author. For the co-author's commit to count as a contribution, you must use the email associated with their {% data variables.product.product_name %} account.
{% if currentVersion == "free-pro-team@latest" %}
If a person chooses to keep their email address private, you should use their {% data variables.product.product_name %}-provided `no-reply` email to protect their privacy. Otherwise, the co-author's email will be available to the public in the commit message. If you want to keep your email private, you can choose to use a {% data variables.product.product_name %}-provided `no-reply` email for Git operations and ask other co-authors to list your `no-reply` email in commit trailers.
For more information, see "[Setting your commit email address](/articles/setting-your-commit-email-address)."
{% tip %}
**Tip:** You can help a co-author find their preferred email address by sharing this information:
- To find your {% data variables.product.product_name %}-provided `no-reply` email, navigate to your email settings page under "Keep my email address private."
- To find the email you used to configure Git on your computer, run `git config user.email` on the command line.
{% endtip %}
{% endif %}
### Creating co-authored commits using {% data variables.product.prodname_desktop %}
You can use {% data variables.product.prodname_desktop %} to create a commit with a co-author. For more information, see "[Write a commit message and push your changes](/desktop/contributing-to-projects/committing-and-reviewing-changes-to-your-project#4-write-a-commit-message-and-push-your-changes)" and [{% data variables.product.prodname_desktop %}](https://desktop.github.com).

### Creating co-authored commits on the command line
{% data reusables.pull_requests.collect-co-author-commit-git-config-info %}
{% data reusables.pull_requests.commit-message-with-trailer-beginning %}
3. On the next line of the commit message, type `Co-authored-by: name <name@example.com>` with specific information for each co-author. After the co-author information, add a closing quotation mark.
If you're adding multiple co-authors, give each co-author their own line and `Co-authored-by:` commit trailer.
```shell
$ git commit -m "Refactor usability tests.
>
>
Co-authored-by: <em>name</em> &lt;<em>name@example.com</em>&gt;
Co-authored-by: <em>another-name</em> &lt;<em>another-name@example.com</em>&gt;"
```
The new commit and message will appear on {% data variables.product.product_location %} the next time you push. For more information, see "[Pushing changes to a remote repository](/articles/pushing-commits-to-a-remote-repository/)."
### Creating co-authored commits on {% data variables.product.product_name %}
After you've made changes in a file using the web editor on {% data variables.product.product_name %}, you can create a co-authored commit by adding a `Co-authored-by:` trailer to the commit's message.
{% data reusables.pull_requests.collect-co-author-commit-git-config-info %}
2. After making your changes together, at the bottom of the page, type a short, meaningful commit message that describes the changes you made.

3. In the text box below your commit message, add `Co-authored-by: name <name@example.com>` with specific information for each co-author. If you're adding multiple co-authors, give each co-author their own line and `Co-authored-by:` commit trailer.
