Learning Center and sign in

Learning Center

The Learning Center helps you get started with quick in-app walkthroughs and other resources for learning about Docker.

To access the Learning Center, select the Learning Center tab in Docker Desktop.

Sign in to Docker Desktop

Docker recommends that you authenticate using the Sign in option in the top-right corner of the Docker Dashboard.

Once logged in, you can access your Docker Hub repositories directly from Docker Desktop.

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.

In large enterprises where admin access is restricted, administrators can Configure registry.json to enforce sign-in. Enforcing developers to authenticate through Docker Desktop also allows administrators to improve their organization’s security posture for containerized development by taking advantage of Hardened Desktop.


Docker Desktop automatically signs you out after 90 days, or after 30 days of inactivity.

Credentials management for Linux users

Docker Desktop relies on pass to store credentials in gpg2-encrypted files. Before signing in to Docker Hub from the Docker Dashboard or the Docker menu, you must initialize pass. Docker Desktop displays a warning if you’ve not initialized pass.

You can initialize pass by using a gpg key. To generate a gpg key, run:

$ gpg --generate-key

The following is an example similar to what you see once you run the previous command:

GnuPG needs to construct a user ID to identify your key.

Real name: Molly
Email address: molly@example.com
You selected this USER-ID:
    "Molly <molly@example.com>"

Change (N)ame, (E)mail, or (O)kay/(Q)uit? O
pub   rsa3072 2022-03-31 [SC] [expires: 2024-03-30]
      <generated gpg-id public key>
uid                      Molly <molly@example.com>
sub   rsa3072 2022-03-31 [E] [expires: 2024-03-30]

To initialize pass, run the following command using the public key generated from the previous command:

$ pass init <generated gpg-id public key>

The following is an example similar to what you see once you run the previous command:

mkdir: created directory '/home/molly/.password-store/'
Password store initialized for <generated gpg-id public key>

Once you initialize pass, you can sign in on the Docker Dashboard and pull your private images. When Docker CLI or Docker Desktop use credentials, a user prompt may pop up for the password you set during the gpg key generation.

$ docker pull molly/privateimage
