Use a secure network with a Chromecast device
We recommend that you use a secure network with your Chromecast device.
While it's good security practice in general, using a secure network will also help prevent others from joining your Wi-Fi network without your knowledge and casting content to your TV. Be extra careful whenever you go online using a network you don’t know. Learn more about setting up your home router and Wi-Fi network securely here.
