Nintendo Switch owners are reporting that they are unable to unlink their Nintendo account from their Switch. This means that if someone steals your Switch, they will be able to use it without having to sign in to your account. Nintendo has not yet released a statement on the issue. This problem appears to have started happening after the release of Super Smash Bros. Ultimate. Some users have reported that they were unable to unlink their accounts even after following instructions from Nintendo support. If you are experiencing this problem, it is recommended that you try the following:

  • Reset your Switch by holding down the power button and selecting “reset system” from the main menu
  • Sign out of your account on Nintendo’s website and then sign back in
  • If those methods do not work, contact Nintendo customer support ..
