I already commented on this, but do they actually block you from setting up multiple devices with the same key?
I’ve had my own server node for a while, there’s nothing stopping me from using the same key and config on multiple client devices, as long as I don’t connect them at the same time.
I’m not limited to five keys, obviously, but the keys aren’t device specific. I could set up just one on the server, and then use it everywhere.
Does Mullwad stop this in some way?
Well yeah, you’d still have the limitation that you can’t connect multiple devices at the same time. But the idea is that just like before, nothing is actually stopping you from having as many devices as you like ready to go, all able to be used one at a time.
