In the url of the login page when it asks you to enter the birthday there will be a bit somewhere that says
"badpassword" if both the pass word and the birthday are wrong but if you put in the right password it will just ask you for the birthday
I think this is right It's worked for me in the past

So for example this is with the wrong password
"http://www.neopets.com/badpassword.phtml?username=zurroa&errcode=1&destin ation=%252Findex.phtml&failed_bday=0"

But if you have the right password that 'badpassword' bit goes away
