[support] Adding the User Login to a Node?

How do I add the user login screen (http://localhost/user/login" to a node so that when I access that node (http://localhost/node/NN), I get the login screen? I think this is essentially referencing another node, which I thought could be done with [node:user/login], but that doesn't seem to be working for me. I thought I had found on the drupal site how to do this, but the search results are not returning what I remember. I apologize for my poor memory. Thanks for any tips.
