Chromecast, if you don't already know, is Google's version of a streaming device that attaches to your TV and allows you to push content to it using a computer or mobile device. We have said this is a great option for schools that have gone Chromebook, or simply want a ~$30 option to stream content to their HDMI enabled projectors.
Google has rolled out Guest Mode, which allows Chromecast owners to enable a setting that opens the Chromecast up to guests – without that guest having to be on your network. This currently only works with Android devices, but it wouldn't surprise me if the functionality makes its way to iOS in the near future. Here is how it works:
“When guest mode is turned on, Chromecast emits a special WiFi beacon. When a Google Cast Ready app is launched on your guest's mobile device, that device detects the presence of the special WiFi beacon and shows the Cast icon in the application. Upon tapping the Cast icon, casting to a ‘Nearby Device' will be listed as an available option.
Your Chromecast then generates a random 4-digit PIN that is required to cast to it using guest mode. When a device nearby tries to connect, the Chromecast automatically transfers that PIN using short, inaudible audio tones. If the audio tone pairing fails, your guest will be given the option to connect manually by entering the 4-digit PIN found on your Chromecast backdrop and in the Chromecast app.”
