What are the SmartStamp passwords for?
For extra security, SmartStamp has two passwords so that you can choose to allow one person to view account information and top up the account using the Account password and another person to print the postage using the Printing password. When you register for SmartStamp, these two passwords are set to be the same, but you can then choose to change them. Your SmartStamp passwords may also be different from your password for the Royal Mail site.
