How to stop people using my dodo code

If you have unwanted visitors Press - button to end session.. or go to airport and end communications.. a dodo code only lasts as a one time code so once you've closed communications people can't visit without a new code

You have to do this on your game on switch.. closing a code on a forum/ website does not close it on your island .

Added info. I checked your dodo code post in the other area. You restricted your island to 1 visitor. This is good. The problem was the player that got your restricted dodo code posted it in the comments below your posting. Keep in mind the advice from Eliza and use it.

The fastest way to end the game is to use the Home Button and close the game. There still might have an auto save but it is way faster and won't mess up your game.
