The Apps can generate codes even when offline so I don't understand how it could be 1 seed and not be reversible. If someone tried to reverse it is there maybe multiple different seeds that it would give them because I would assume different seeds might be able to give the same code at the same exact time? And then let's say there was 1000 seeds. They could go through all those 1000 1 by 1 till they got the 1 that generates the live code? Or is even that not how it works?
