No way to know if the password is revealed or not
There is an option to reveal the password we are typing, which is great, though there is no visual change if the password is revealed or not, which can be dangerous as we may start typing our password, not knowing it will be readable by persons around. The icon should be different if it's revealed or not.
I don't know if we should display the icon of the current state or the other state though, maybe @bertob has a suggestion there?
