How to set up and use guest mode on Chromecast

Guest mode in Chromecast allows any of your guests to cast video to the bigger screen of your home TV without even being connected to your home WiFi network. Let’s take a look at how to set up and use guest mode on Chromecast.

Guest mode on Chromecast

Google Chromecast originally required guests to be connected to your home WiFi network in order to cast video from their mobile device to the larger screen of your home TV.

Now Google has made Chromecast guest mode even better and more secure, allowing anyone in the same room to cast photos and videos to your TV screen without actually being connected to your home WiFi network.

This way your guests can share their favorite videos with everyone in the room using their mobile phones and not having to log into your home WiFi network.

Note: Your guest’s mobile device must have an active cellular plan or be connected to the internet through another Wi-Fi network to use guest mode on your Chromecast device.

How Chromecast guest mode works

When you enable guest mode on your Chromecast, it emits a special WiFi beacon. This WiFi beacon is then detected by the guest mobile device when YouTube or another Chromecast-enabled app is played on the guest mobile device.

Whenever your guests launch a Chromecast-enabled app on their mobile device, the WiFi beacon emitted by your Chromecast will be detected by the guest’s mobile device and they will see the Cast icon on their mobile devices.

By tapping the cast icon, your guests can choose a nearby device (your TV) to cast the video to.

Whenever your Chromecast detects a nearby device trying to connect, it generates a 4-digit PIN and attempts to transmit that PIN to the nearby device using inaudible audio tones.

If this audio-sound pairing fails, your guest will have to manually enter the 4-digit PIN displayed on your TV screen.
