By default, GitHub Enterprise Server uses built-in authentication. Each person creates a user account on your GitHub Enterprise Server instance from an invitation or by signing up, and then authenticates with the credentials for the account to access your instance. Your GitHub Enterprise Server instance stores the authentication information for the account.
You can prevent unauthenticated people from creating new user accounts on your instance. For more information, see "Disabling unauthenticated sign-ups."
Alternatively, you can configure external authentication for your GitHub Enterprise Server instance. If you use external authentication, you must invite people to use your instance through your authentication provider. For more information, see "About authentication for your enterprise."
