You can sign in with your email, Google or GitHub account, or from the Docker CLI.

Go to the Docker sign in page.
Enter your email address or Docker ID and select Continue.
Enter your password and select Continue.

To reset your password, see Reset your password.

重要
Your Google or GitHub account must have a verified email address.

You can sign in using your Google or GitHub credentials. If your social account uses the same email address as an existing Docker ID, the accounts are automatically linked.

If no Docker ID exists, Docker creates a new account for you.

Docker doesn't currently support linking multiple sign-in methods to the same Docker ID.

Use the docker login command to authenticate from the command line. For details, see docker login.

警告
The docker login command stores credentials in your home directory under .docker/config.json. The password is base64-encoded.
To improve security, use Docker credential helpers. For even stronger protection, use a personal access token instead of a password. This is especially useful in CI/CD environments or when credential helpers aren't available.

Reset your password

To reset your password:

Go to the Docker sign in page.
Enter your email address.
When prompted for your password, select Forgot password?.
