Thanks to the latest Chromecast tweak, you no longer need to give out your Wi-Fi password if a house guest wants to share the latest hit YouTube video on your TV.
With the new Guest mode, you can open your Chromecast's digital gates to your friends' and family's Android devices. Once you do, they'll be able to stream a movie, TV show, or video from one of the growing number of Chromecast-friendly apps without the need to join your Wi-Fi network.
Once guest mode is turned on, the Chromecast emits a Wi-Fi beacon that other devices can find when looking to cast a video. If an app doesn't connect automatically, there's a four-digit PIN on screen that you'll need to type in. After doing this, all your cat videos or Netflix favorites can be shared on the bigger screen.
You can turn off guest mode when the party's over, so neighbors can't hijack your Chromecast and send you annoying videos.
Google first announced this feature in June at I/0, so we're glad to finally see it make its way into the real world. It doesn't require an update, so check out your Chromecast app and it might already be there.
The impact on you: You no longer need to worry about network security, because you don't need to hand out your Wi-Fi password to enable anyone to share a video on your TV.
