Password Checkup – A Chrome Extension That Protect Your Accounts From Data Breach

A new Chrome Extension called Password Checkup will automatically check whether your passwords have been exposed in a data breach. This new Password Checkup Extension by Google for Chrome browser will help you to resecure accounts that were affected by data breach.

According to Google, “If we detect that a username and password on a site you use is one of over 4 billion credentials that we know have been compromised, the extension will trigger an automatic warning and suggest that you change your password.”

How Password Checkup Works

Whenever you enter a username and password to sign in to your account, Password Checkup Extension will check your password. In case if that password is no longer safe due to appearing in a data breach, you’ll receive an alert.

If you get alert like this then you should change the password as soon as possible. And If you use the same username and password for any other accounts, you should reset your password there as well.

How To Install Password Checkup?

  1. Open the Chrome browser.
  2. Click here to open the Password Checkup extension on the Chrome Web Store.
  3. Click on “Add to Chrome”
  4. Once installed, a green shield icon will appear on the top right corner of the browser. The icon will turn red if the password match with the data breach.

Google said in a blog that it won’t show alert for the weak password like 123456, but only give an alert if your current username and password appear in a data breach, as that poses the greatest risk.


Google will be reading your usernames and passwords every time you log into a website. However, according to Google, they designed Password Checkup with privacy-preserving technologies to never reveal this personal information to Google.
