Altough the FAQ from the toontown official site has been removed from the options bar you could still go to News archives......one of the post (I don't know which one though) will re-direct you to the FAQ page......from there in the search box in the FAQ page type in lost my password.....they should ask your or email you something that says user name or it mght ask you for your e-mal address.......if they approved everthing else.....presto your password has arrived...
I hope I was able to help........
P.S.I did this a long time ago....they might have reprogramed the web-site so, I'm not 100% sure it'll work...good luck though........
