If any browser can be a camera, why do you require me to register to try it out? I'm not ready to give you my personal details. You say below privacy is your primary concern, but you require us to give up our privacy just to try it out.

I guess they could do without the registration part if the demo only involved streaming your own video back to the same device. But the primary use case seems to be streaming from one private device to another (not broadcasting to the world), and for that they need a way to determine which devices are allowed to access which streams.

In most web frameworks, accepting signups and associating sessions with user accounts is the safest and easiest way to achieve this.

Or start the camera on the current device, show a code, enter that code on another viewing device.
