Thank you for the feedback and wormhole.app suggestion! As for QR code - it's already available after you've set up your session, but UI might not be as obvious

Thank you for the feedback and wormhole.app suggestion! As for QR code - it's already available after you've set up your session, but UI might not be as obvious so I'll work on it. For PIN code - you might be right, though brute forcing PIN codes with 6 alphanumeric characters and throttling on signaling server might not be as easy as it seems. Communication inside a sharing session is end-to-end encrypted as it uses WebRTC, and session will "expire" as soon as all clients are disconnected, because no data is stored on a server - it's all between connected clients
