Alarmingly, Google now deploys hidden trackers on 76% of websites across the web to monitor your behavior and Facebook has hidden trackers on about 25% of websites, according to the Princeton Web Transparency & Accountability Project. It is likely that Google and/or Facebook are watching you on most sites you visit, in addition to tracking you when using their products.

Eric Schmidt, former Google CEO and Chairman, famously said “Google’s policy on a lot of these things is to get right up to the creepy line, but not cross it.” But for most people, that line was crossed by Google, Facebook, and others long ago.

Before we get to passwords, surely you already have in mind that Google knows everything about you. It knows what websites you’ve visited, it knows where you’ve been in the real world thanks to Android and Google Maps, it knows who your friends are thanks to Google Photos. All of that information is readily available if you log in to your Google account. You already have good reason to treat the password for your Google account as if it’s a state secret.
