Passwords for purchasing accounts can be viewed at ims.1ticket.com/accounts. If you only see asterisks on that page instead of passwords it means you don't have permission to view passwords.
If you're an Admin in your 1Ticket account you can grant yourself (and any of your employees) permission to view passwords at 1Ticket.com/users. If you're an Admin you'll need to find someone in your company who is.
