I have an "RK-" recovery key in my backup from when I set it up a couple of years ago. However today I see no reference to recovery codes whatsoever, either on my account or during attempts to recover my password. I just now stripped two-factor auth entirely, and set it up again from scratch. There is absolutely no reference to a recovery key anywhere[1].
It must depend on which devices and/or OS versions one is running. I've got a 2013 MacBook Pro on High Sierra and an iPhone 6 on iOS 11 (latest software on both). I also have a confirmed phone number. I no longer have the option for a recovery code with two-factor auth[1].
