The name on your certificate is based on the name you provided for your account. If your name has changed or is otherwise inaccurate, it is easy to change the name on your account (which will also change your name on any certificates of completion you download). Just follow these steps:
Visit the "Edit Account" section of the myAccount dashboard
Enter your first name, middle name or initial (optional), and last name in the fields at the top of the page.
Click the "Save changes" button at the bottom of the page.
After following these steps, any certificates of completion you download should have your updated name.
