I read almost every week about a data breach at some large company, so then the bad guys may now have another one of my passwords, but what can I do about it? Well, Google has a list of all known data breaches and when you add their new extension to the Chrome browser and visit a web site that has been breached, it will alert you to change your password.
I've been using this Chrome extension for a couple of weeks now and just yesterday it alerted me to change my account password on a particular web page that I use about once per year:
Kudos to Google for making this password checking feature free to Chrome users. At least I know that my old password has been hacked, and that it is time to update it before some bad guy steals my identity for that particular web site.
