Thanks for the feedback.
Yes, there is a possibility to hide your custom password. Don't put it into the prefix field, as suggested by the faq, but use the Advanced Auto-Populate tab. There you can set up username and password, and the password will be hidden from view.
At the moment it is not easily possible to hide the accounts completely.
To make this a feature request, would you like to have just the accounts hidden, or all of PasswordMaker's dialogs, before the MPW is entered correctly? This would imply also, that the MPW's hash is stored for verification, but that's another feature request.
