A new Chrome Extension from Google called Password Checkup will automatically check whether your passwords have been exposed in a data breach. Once installed, the extension checks any login details you use — Google says “most” US sites are supported — against a database of around four billion usernames and passwords, and warns you if it finds a match.
Password breaches are an unfortunately common occurrence, but so long as you’re using a unique password for each website it’s normally fairly simple to deal with. Just change the login credentials used with the breached website, and move on.
