Firebase has well-documented rules to allow only users with authentication to read/write from/to nodes. I am using OpenShift to setup a CRON server that will occasionally ping my Firebase database and write values to a node. How do I enforce the rule that only my server will be able to write to that node? Do I have to enforce some sort of admin privilege. Or pass a secure key?
My search yielded this link. However, I think that question addresses a different problem.
