The massive and numerous data breaches over the last few years prove at least one thing: Passwords alone can’t protect you. And as if to remind you that 2019 will be just as fraught with cybersecurity issues as the year before, security researcher Troy Hunt discovered yet another major breach, ominously titled “Collection #1,” in which nearly 773 million email addresses and 21 million passwords were exposed.
