Did you know that you can download an app for your smartphone to control your WDTV? I did, but did you also know that said app requires no authenticiation to interact with your device, even if you’ve set up a password for the WDTV? I discovered this when some friends were over one night. I went upstairs to put my son to bed, and when I came back downstairs I found one of my friends merrily browsing YouTube videos on the WDTV with his phone.
The device should have an option to require a password to interact with it. Even Bluetooth devices require a code for pairing.
