# Create and manage users When using the Docker Datacenter built-in authentication, you can create users to grant them fine-grained permissions. Users are shared across Docker Datacenter. When you create a new user in Docker Universal Control Plane, that user becomes available in DTR and vice versa. To create a new user, go to the **DTR web UI**, and navigate to the **Users** page. ![](../images/create-manage-users-1.png) Click the **New user** button, and fill-in the user information. ![](../images/create-manage-users-2.png) Check the **Trusted Registry admin** option, if you want to grant permissions for the user to change Docker Datacenter configurations. ## Where to go next * [Create and manage organizations](create-and-manage-orgs.md) * [Create and manage teams](create-and-manage-teams.md)
