Last January Google quietly did away with the existing Guest Mode feature, which allows people not on your Wi-Fi network to connect with a Chromecast or smart speaker by entering a four-digit PIN, from its Home and Nest devices on account that some people and pets could hear the ultrasonic frequencies the two devices use to pair. Today, in the culmination of online privacy efforts the company first announced back in October, users will be able to turn off the voice recording features of their smart display and speaker like the Nest Audio or Nest Hub Max simply by telling it to. This new Guest Mode is basically like Chrome’s Incognito tabs.
