Removing old Passport email addresses from the Sign In window

[Guest]

I was just wondering how to do this, there's over 40 addresses in it, when
you push the arrow, and it's just annoying - Mostly from other people who use
my PC - Is there an option to clear them, like the "History" in IE? ANY
input is appreciated!
