We want our websites and email accounts to be safe, convenient, and private, though sometimes we have to settle for two out of three. But Google has just announced a new invisible, convenient authentication system that works by following you around the Internet like a nosy little sibling.

This isn't a huge leap from Google’s current “No CAPTCHA reCAPTCHA” system, which monitors how you move through a given website to see if you’re acting like a person. Then, the big test: checking a box that says “I am not a robot.”
