Hmmm, that makes managing project's security a little more interesting. If I understand correctly, I will be creating unique key pairs for every instance of node-red and github combo. Correct?
Apologies, I admit to not giving this thread full attention. I assume you are using the Node-RED projects feature?
If so, I don't use that and all my git usage is from the command line or VScode. I guess you would need to search for the private key. I imagine that it will be inside your projects folder somewhere.
OK, well as I don't use projects, I've already over-reached my knowledge. If the documentation is lacking or incorrect, I'd suggest nipping onto the Node-RED Slack. There is a #docs channel there and you can chat with Nick or Dave about documentation updates.
