Docker ID accounts

Your free Docker ID grants you access to Docker Hub repositories, and some beta programs. All you need is an email address.

This account also allows you to log in to services such as the Docker Support Center, the Docker Forums, and the Docker Success portal.

Register for a Docker ID

Your Docker ID becomes your user namespace for hosted Docker services, and becomes your username on the Docker Forums.

1. Go to the Docker Hub signup page.

2. Enter a username that is also your Docker ID.

   Your Docker ID must be between 4 and 30 characters long, and can only contain numbers and lowercase letters.

3. Enter a unique, valid email address.

4. Enter a password between 6 and 128 characters long.

5. Click Sign up.

   Docker sends a verification email to the address you provided.

6. Click the link in the email to verify your address.

Note: You cannot log in with your Docker ID until you verify your email address.

Log in

Once you register and verify your Docker ID email address, you can log in to Docker Hub and Docker Support.

You can also log in using the docker login command. (You can read more about docker login here.)

Warning: When you use the docker login command, your credentials are stored in your home directory in .docker/config.json. The password is base64 encoded in this file. If you require secure storage for this password, use the Docker credential helpers.
