The new update adds support for Apple's Two-Factor Authentication system, adding an extra layer of security when signing in for Home Sharing purposes. Using Home Sharing will now require a verified device or a verified phone number that can receive a Two-Factor Authentication code, preventing an unauthorized user from accessing a home library with just a password.
For those unfamiliar with Two-Factor Authentication, it is an opt-in system that's designed to increase the security of Apple ID accounts. It asks users to provide a verified code when signing in to new devices, when using iCloud, and when using services like iMessage and FaceTime.
Apple's iTunes Remote app was last updated in September of 2016, adding iOS 10 compatibility and minor performance and stability improvements. The app lets users browse their iTunes libraries and send music to AirPlay speakers.
The iTunes Remote app can be downloaded from the App Store for free. [Direct Link]
