GitHub helps software engineers manage everything from their own projects to complex development workflows with larger companies. In this course—one of seven installments in the GitHub Foundations series—work towards GitHub certification as you learn how to secure your GitHub account with 2FA, access permissions, and EMUs, as well as configure and manage repositories and organizations. Noah Gift, an author and Executive in Residence at Duke University, breaks this course into two sections, focusing first on authentication and security and then on administration. In the latter section, he covers enabling and disabling GitHub features, demystifies repository permission levels and visibility options, and more.
