Just to be clear, if you are referring to the secure mail key then that is only for email client apps (e.g., Thunderbird, Outlook, mobile email client apps, etc.) not the webmail. So is your reference to a "Secure Email Password" actually what's called a "secure mail key" and were you trying to use it in an email client because as I said it won't work to log into the webmail. For the webmail you still need your account password.
