Can you please guide me how different user can create different flows and they can be stroed user wise?
what operating system are you running on ?
One Node-RED instance is shared among all users who have access, so are all flows in that instance.
You can setup different users in the settings.js, but that is for authentication purposes only.
You'd have to run a separate Node-RED instance for each user. There are some examples for that, if you search the forum. Like this one: Node red multiple instances
As we said before it is not possible but there are other options like multiple instances.
I am closing this duplicate thread
Please continue this conversation on the original thread Node red for Individual User
@kuema that is the same thread I linked the OP to in his other thread.
