Broken pnid/nnid

I can’t play anything. I made my account to play splatoon like an hour ago. When i try to join any nnid/pnid games, it asks me to re-enter my password. I put it in correctly, and it says incorrect password. I want to play!!! :frowning: Help!!

Update: It has been a day and my pnid works. I can’t play splatoon on sssl right now, but it’s better than nothing.

Only Mario Kart 8 and Super Mario Maker works on SSSL right now as far as I know
