Like sharing your WLAN. It works great between iPhones, if you know how it works and the preconditions are fulfilled (it's undiscoverable). You can't share with Android devices by showing them a QR code – which I would consider the "usual" way and which is easy to do on Android devices.

Edit:

Here is the procedure I was talking about and all prerequisites for it to work:

iOS hotspots are discoverable by non-Apple devices if you have "Allow Others to Join" enabled and have the Personal Hotspot settings panel open on the iOS device. Otherwise, it's hidden to help prevent unintended connection attempts.

I suspect they mean sharing the password for a regular wifi network, not running a hotspot.

		That feature hardly works between iPhones anyway. It’s easier to just open the passwords app and show the QR code.

It has never worked for me on iOS. Everyone kept saying "I can just share the password" but the prompt never popped up, and there was no way to do anything.

		IIRC it only works if you are on their contact list. And I think you need to be in the settings app. Something like that. It's a handy feature but Apple could make it easier to understand, and they could do way better communicating why it isn't working, when it does not work.
