Hi @marcus-j-davies,
Thanks for sharing this tutorial!!
It is very nice to see something about security popping up, because it might help a lot of users.
That is something I have also been wondering about in the past. I have never tested it, but I assume my smartphone gets a new ip address often from my provider. Or when I travel abroad, my phone probably will get another IP address from the foreign provider. Then I wouldn't be able to access my Node-RED system. Or do you have other thoughts about this?
