TightBeam works differently from other end-to-end encrypted messaging applications by ensuring the person you are communicating with is who you think they are. This is accomplished by establishing the connection in person! TightBeam cleverly uses QR codes to transmit a one time secure key between two iOS devices. Once this secure key is received, a secure communication channel is established between the two devices. This allows you to have confidence that you are sending and receiving messages with your trusted contact. No one can listen in, and no one can setup a man-in-the-middle attack.
