HTML password fields

Do not pass values to HTML form input type password fields.
This is such a common thing with password fields that I'm surprised a solution doesn't already exist.  It almost feels like the HTML tag itself should have a "populated" parameter or something, so you can leave the value blank, but it will display 8 stars or maybe a faded background string like "password saved" or something.

Perhaps you can use the `placeholder` attribute with 8 stars?
