You've probably heard by now that Facebook was hacked over the weekend and that about half a billion FB users' info was breached. The information that was breached includes sensitive personal data like birthdates, locations, phone numbers, names, email addresses, etc. If you're worried that your account may have been one of them, you can check this website: haveibeenpwned.com. The website is run by a third-party that will only check to see if your email was in the data that was stolen.
