I set up two-factor authentication to use the unlock with watch feature on my Mac.

I set it up and had no problem getting the authentication codes to login to iCloud on my mac, login to iCloud.com, etc. But when I try to login to iCloud on my iPhone (6s running iOS 10), it says the code from my mac is not valid. I tried with the one provided in the pop-up window that tells me someone is trying to login, as well as going into System Prefs > iCloud > Account Details > Security > Get Verification Code.

Any advice? I had to disable two-factor authentication in the mean time to be able to access the contacts on my phone. But I'd like to get to the bottom of this.

Thanks in advance for any help you can provide.
