In a new blog post entitled "Keeping Passwords Secure"
Facebook VP Engineering, Security and Privacy Pedro Canahuati explains how the social media giant accidentally stored Facebook user's passwords on internal data storage systems in plain text. Pedro explains how "these passwords were never visible to anyone outside of Facebook and we have found no evidence to date that anyone internally abused or improperly accessed them. We estimate that we will notify hundreds of millions of Facebook Lite users, tens of millions of other Facebook users, and tens of thousands of Instagram users." To keep your account safe, Facebook suggests changing your Facebook and Instagram passwords, pick strong passwords, use a password manager, and enable a security key or two-factor authentication.
