To see your passwords as they are typed into this password entry dialog, right click on the window caption and select the Reveal Password option. Unchheck this item to turn this feature off.
A shortcut to do the same thing is to double-click on the red background of the dialog. Each double-click action toggles the revealed password state.
SafeHouse will remember this state until you personally change it back.
When the reveal password state is enabled, each time you display this dialog you'll see this <Visible> text in the password entry field.
This text disappears as you type your first character. This way, you'll never mistakenly start typing a visible password when you know people are close by. And if somebody is close by, a quick double-click on the red dialog background toggles this state back to hidden passwords.
