Quote:Google has released a new Chrome extension named "Password Checkup" that checks if usernames and password combinations entered in login forms have been leaked online during past data breaches and security incidents.

The extension works every time users log into an online service. The extension takes the username and password entered in the login form and checks them against a database of over four billion credentials that Google engineers have collected from public breaches in the past few years.

If the username and password combo are found in Google's internal database of unsafe credentials, the extension will show a popup alerting the user that he needs to change the credentials.

Official Google Announcement - The Password Checkup extension can be downloaded from the official Chrome Web Store, here.
