I have the following devices and operating systems:
- Apple Watch (running watchOS 3, Seed 2)
- MacBook Pro 15" Retina (running macOS Sierra 10.12, Seed 2)
- iPhone 6S Plus (running iOS 10, Seed 2)
I want to test out the new Auto Unlock feature and in reading the release notes, I see that I have to enable Two-Factor Authentication. I went onto my MacBook and tried to enable it, but I'm receiving the following error message:
Two-factor authentication is not available for your Apple ID at this time.
I do not have two-step authentication enabled either, so it is not due to that, since I know you cannot have both enabled. I tried to enable two-factor authentication on my iPhone but the option does not appear at all when going to Settings > iCloud > Apple ID > Password & Security.
Does anyone know what is causing this or does anyone have the same issue?
