Niltalk lets you create instant, password protected chat rooms without the need to signup. Simply click the "Create" button, and share the unique chat URL with your peers.
All communication happens over SSL. Niltalk doesn't record or log IP addresses, messages, or peer handles anywhere. Once a room is created, it has a lifetime of 120 minutes before the first login. Then, the room is automatically deleted after 10 minutes of inactivity (no messages exchanged). While in a room, you or any of your peers can dispose of the room with the click of a button.
