This page describes how to login to your Lobby Bot for Fortnite
When opening the lobby bot for the first time (
ProSwapper_LobbyBot.exe) it will ask you to enter an authorization code. This authorization code is used to login to the Fortnite account of the bot. You can get your authorization code here by logging in to the desired Epic Games account which the bot will use.
The authorization code is the 32 letter long text.
