I don't know whether this is a Google problem or a CM problem, but 2-factor authentication to Google services just doesn't work through the initial guided setup. It almost works; it launches the browser to let you log on and enter the authentication code. However, there's no way to view the code once it's texted to you, so you can't sign on to your Google account. You just have to skip pretty much everything in the initial setup and return to it later, doing everything manually.
This ROM also doesn't seem to be able to turn on wifi as part of the initial setup either. Same was true with the Aviator CM10.1 ROM. Reboot to recovery, scrub cache/dalvik and you're good to go.
I still like it, though . . . once you're past the initial glitches, it's pretty great.
