I mean, come on. Some of the basic functionality of our devices must be something that could be modified by asking Siri to take care of it, don't you think? Apple means beautiful simplicity, not layers of menus to navigate and guess at functionality.
Although I'd certainly like none of us to be having issues, I'm glad to hear I'm not the only one with 2-factor authentication enabled having issues. Everything worked fine for me but then I went to set things up on a new Mac and that's really wreaked havoc here. Now on my existing Mac I can no longer see my iPhone phone number as a valid address to use in FaceTime or iMessage. In addition, when I turn on the Text Forwarding switch in the iPhone and I'm supposed to get a code on my Mac I get...nothing. So I not only can't send SMs messages from my Mac, I can't even receive iMessages on my Mac iMessages that are addressed to my phone number (which is what everyone uses to send me iMessages--since, after all, most people think they're just sending texts from their iPhones). What a freaking mess. Come on, Apple: fix this crap! Now I'm faced with either turning off 2-factor authentication or not being able to work properly.
