 Docker Desktop is an easy-to-install application for your Mac or Windows environment
 that enables you to build and share containerized applications and microservices.

 Docker Desktop works with your choice of development tools and languages and
 gives you access to a vast library of certified images and templates in
 [Docker Hub](https://hub.docker.com/). This enables development teams to extend
 their environment to rapidly auto-build, continuously integrate, and collaborate
 using a secure repository.

-## Sign in to Docker Desktop
-
-After you’ve successfully installed and started Docker Desktop, we recommend
-that you authenticate using the **Sign in/Create ID** option from the Docker
-menu.
-
-Authenticated users get a higher pull rate limit compared to anonymous users. For example, if you are authenticated, you get 200 pulls per 6 hour period, compared to 100 pulls per 6 hour period per IP address for anonymous users. For more information, see [Download rate limit](../docker-hub/download-rate-limit.md).
-
-In large enterprises where admin access is restricted, administrators can create
-a `registry.json` file and deploy it to the developers' machines using a device
-management software as part of the Docker Desktop installation process. Enforcing developers to authenticate through Docker Desktop also allows
-administrators to set up guardrails using features such as
-[Image Access Management](../docker-hub/image-access-management.md) which allows team
-members to only have access to Trusted Content on Docker Hub, and pull only from
-the specified categories of images. For more information, see
-[Configure registry.json to enforce sign in](../docker-hub/configure-sign-in.md).
