Chrome Can Tell You If Your Passwords Have Been Compromised

Given the frequency of hacks and data leaks these days, chances are good that at least one of your passwords has been released to the wild. A new Chrome extension released by Google today makes it a little easier to stay on top of that: Once installed, Password Checkup will simply sit in your Chrome browser and alert you if you enter a username / password combination that Google “knows to be unsafe.” The company says it has a database of 4 billion credentials that have been compromised in various data breaches that it can check against.
