A Docker ID is a username for your Docker account that lets you access Docker products. To create a Docker ID, you need an email address or you can sign up with your social or GitHub accounts. Your Docker ID must be between 4 and 30 characters long, and can only contain numbers and lowercase letters. You can't use any special characters or spaces. For more information, see [Docker ID](/accounts/create-account/). If your administrator enforces [single sign-on (SSO)](../../security/for-admins/single-sign-on/_index.md), this provisions a Docker ID for new users. Developers may have multiple Docker IDs in order to separate their Docker IDs associated with an organization with a Docker Business or Team subscription, and their personal use Docker IDs. ### Can I change my Docker ID? No. You can't change your Docker ID once it's created. If you need a different Docker ID, you must create a new Docker account with a new Docker ID. Additionally, you can't reuse a Docker ID in the future if you deactivate your account. ### What if my Docker ID is taken? All Docker IDs are first-come, first-served except for companies that have a U.S. Trademark on a username. If you have a trademark for your namespace, [Docker Support](https://hub.docker.com/support/contact/) can retrieve the Docker ID for you. ### What’s an organization? An organization in Docker is a collection of teams and repositories that are managed together. Docker users become members of an organization once they're associated with that organization by an organization owner. An [organization owner](#who-is-an-organization-owner) is a user with administrative access to the organization. For more information on creating organizations, see [Create your organization](orgs.md). ### What's an organization name or namespace? The organization name, sometimes referred to as the organization namespace or the organization ID, is the unique identifier of a Docker organization. The organization name can't be the same as an existing Docker ID. ### What are roles? A role is a collection of permissions granted to members. Roles define access to perform actions in Docker Hub like creating repositories, managing tags, or viewing teams. See [Roles and permissions](roles-and-permissions.md). ### What’s a team? A team is a group of Docker users that belong to an organization. An organization can have multiple teams. An organization owner can then create new teams and add members to an existing team using Docker IDs or email address and by selecting a team the user should be part of. See [Create and manage a team](manage-a-team.md). ### What's a company? A company is a management layer that centralizes administration of multiple organizations. Administrators can add organizations with a Docker Business subscription to a company and configure settings for all organizations under the company. See [Set up your company](/admin/company/). ### Who is an organization owner? An organization owner is an administrator who has permissions to manage
