The Mario Marathon passport is a new game for Mario Marathon 2017. The goal is collect as many stamps as you can. Stamps represent milestones and events that will occur throughout the marathon. When these milestones are achieved (e.g. defeating Bowser) a notification will show up on the stream with a claim code. Enter the claim code on your personal passport page to add the stamp to your passport. In addition to on stream milestones, some passport stamps are associated with viewer activity, and will automatically be added to your passport. Some stamps have secret unlock criteria. If you can figure out the secret, you can claim the stamp!
