Email ata. I forgot mine & didnt use a legit email address so they rest that info for me a while back.
You can change your password within the app, go to settings, account management, ATA account, change password. Or you can go to www.partyinmydorm.com/transfer You can reset your password here, you type in your ATA email, and it will send an email on what to do next to the email address that is linked to the account.
