It's basically just a unique ID that way my server has some way to identify your progress across any sessions you play. You can just spam the generate key a bunch of times to get a random one and then once you have one you like create a new text document whereever and name it your card ID as well as paste the card ID in the text document itself. Now every-time you load into MGA press the 'insert card' key-bind and it will then load your information. Idt Teknoparrots work with SpiceTools but I can't say for certain as I'm new to this scene as a whole.
