title: Only allow writes from service account in Firebase?
body: <p>I would like make writes to my Firebase data from a node.js server but deny all writes to any other client.  Any other client should only be allowed read access.  What is the best approach for this?  Would I need to authenticate from node.js server with a special admin account and setup a security rule for that specific account or is there some better way to accomplish this?  Thanks!</p>
