Can I use a yubikey U2F as a second-factor for iCloud sign-in on Mac OS X?

Question

Can I use a yubikey U2F as a second-factor for iCloud sign-in on Mac OS X?

I see that iCloud suports 2FA for login. I have a Yubikey U2F device. Can I currently use this token as (one of) the possible 2FA methods for iCloud login on Mac OS X Mojave?

No. The following has information about Apple two-factor: Two-factor authentication for Apple ID - Apple Support

Also, for a complete list of YubiKey supported services, see: https://www.yubico.com/works-with-yubikey/catalog/

Hmm... did some more searching. Based on this article from Yubico you can use a yubico key for OS login, in one of two ways:

(To be sure, this is different from my original question; that is, whether I could use such a token for 2FA with iCloud.)

Thanks!

Correct. Apples two-factor authentication is designed to protect access to your Apple ID only and not to protect access to any devices.
