Use guest mode for Chromecast Audio

Keeping a close guard on the password for your Wi-Fi network is a security best practice. However, if you’re having an outdoor gathering and you want to be a gracious host, you can still let your guests connect to Chromecast-enabled audio devices so they can select the music. While you’re logged into the same Wi-Fi network as your Chromecast, simply open up the settings for your device from the Google Home app. Then, under “Device settings” enable “Guest mode.”
