Google today announced a Chrome extension called Password Checkup that will help you protect your accounts from third party data breaches. After installing this extension, wherever you sign-in, if you enter a username and password which are already compromised in a data breach, you will receive a warning to reset your password. Since this extension is from Google, you might be worried about your privacy. Google has mentioned that this extension never reports any identifying information about your accounts, passwords, or device. But it reports anonymous information about the number of lookups that surface an unsafe credential, whether an alert leads to a password change, and the domain involved for improving site coverage.

We built Password Checkup so that no one, including Google, can learn your account details. To do this, we developed privacy-protecting techniques with the help of cryptography researchers at both Google and Stanford University.
