You should have already gotten a password when you donated 5,000 and 12,000 points. The worst case is if th password screen popped up when you weren't looking, and it was already gone by the time you came back. But if this has some other reason behind it, then.....Maybe your tama 'forgot' abot it if you donated the points all at once. Try donating 1 or 2 more points to see if you get a password. If nothing works, then there's something wrong with your tamagotchi and you can try resetting it to see if the password donation thing works. Hope I helped!
