Join Code
The eight-character code a Game Master reads out so players anywhere can join their game over the internet.
When the GM opens an internet lobby, the app shows a Join Code such as ABCD-2345. Players choose Join Game, open the Internet tab and type it in; capitals and the dash do not matter. A code only works while that lobby is open. It stops working when the GM closes the lobby or saves and quits, and the next session gets a new one.
