Names matter. We can keep the technical stuff under the hood, while presenting a clean interface for those un-interested in the details. But we can only do that when the thing built right. Notice how you don’t have to share encryption keys when your friends want access to your home wifi?

Even the password part is harder than it should be. Idk why routers don’t just have a button you press when someone wants on the wifi. They knock on the network, a light flashes - press button, they are let in. Would work for most home use.
