title: Why is docker login storing my password in an unencrypted folder, and should I do something about it?
body: <p>I have an application running inside a Docker container, which is continuously being pushed to an Azure Container Registry.  As part of the pipeline I am using the step:</p>
  <pre><code>docker login &lt;Docker Server&gt; -u &lt;Username&gt; -p &lt;Password&gt;
  </code></pre>
  <p>When my pipeline is running this step, I get the following warnings:</p>
  <pre><code>WARNING! Using --password via the CLI is insecure. Use --password-stdin.
  WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
  </code></pre>
  <p>Should I do something about this, and do you have any proposed solutions?</p>
