From Google, a plugin that detects when you type your google.com password into a non-Google web page.

Fake login pages tricks users to give their password to an attacker. These "phishing pages," when well-crafted, are successful about 45% of time. When a password has been stolen, the attacker uses the email account to gather harmful information, or to email others, pretending to be the account holder.
The tool works like a spellchecker, except instead of looking for typos it's looking to see if you enter your Google password into anywhere other than your account sign-in page. If it detects that you've mistakenly entered your password in the wrong place, it immediately alerts you and asks you to change your password to be safe again.
So it is somewhat analogous to cert-pinning for passwords. It would be nice if they expanded it to all website/password combos instead of just google.com

Well, even if they do, they'll probably use two passwords: One for Google, and one for everything else.
And the difference will probably be a "G" attached to the Google password.
