Yesterday, on Let's Talk iOS, we discussed how arduous and tedious it is to enter a password on the Apple TV interface. It's a difficult process, because the Apple TV lacks support for Bluetooth keyboards, and features an A-Z text entry setup that makes the process even more difficult that it was on last generation's Apple TV.
Fortunately, the Apple TV features an option that allows you to never require a password for iTunes & App Store purchases. While using such an option works, it leaves your device open to unauthorized purchases. The good news is that, as we discussed on the podcast, you can easily set up restrictions for App Store and iTunes purchases, which will make it so that purchases only require the entry of a 4-digit passcode.
