title: Docker log in command does not work
body: <p>I have installed boot2docker on on my windows machine and have created a repository on docker hub. I am trying to log in with the following command in the linux shell:</p>
  
  <pre><code>docker login --username=myusername --password=mypassword --email=myemail@gmail.com
  </code></pre>
  
  <p>But I am getting this in the shell: </p>
  
  <p><a href="https://i.stack.imgur.com/o9OvZ.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/o9OvZ.jpg" alt="enter image description here"></a> </p>
  
  <p>The password field appears asking me to enter my password, but when I do and press enter, nothing happens. </p>
  
  <p>Ideas? </p>
