Once installed, you’ll see the Password Checkup icon in your browser bar. Then, every time you sign into a site, Google will check your login credentials to see if they are still safe to use.

If your login credentials aren’t on the database you’ll be free to continue. However, if they match a set in Google’s database you’ll be alerted to the problem. Google will then suggest you change your password to something else not already exposed.

How the password Checkup helps keep your accounts safe

  1. Whenever Google discovers a username and password exposed during a data breach, they store a strongly encrypted copy of that data.
  2. When you log in to a site you use around the web, Password checkup will send an encrypted copy of your username to Google.
  3. Google uses a private set intersection with blinding to search through every unsafe username and password without revealing your account details during the process.
  4. The final check for whether your username or password was in the data breach is entirely local. If your account details were exposed, you should change your password immediately.

Password Checkup is currently available as an extension for Chrome. It is constantly being refined to improve site compatibility and username and password field detection.
