Cached credentials allow relogin without reentering password
@jri As a user I do not save any passwords in my browser. To stay logged in with some websites I allow "Remember me" cookies. When I want to relogin to a website I expect to be prompted for my password with an empty password field. DMX's behaviour is to save the last user name and password (displayed as dots) until I close the browser tab. Once I log out someone else could relogin with the stored credentials.
