My approach to this is to use a google voice phone number where all SMS get sent to email. The voice account and the gmail account are the same google account which is secure by hardware 2FA yubikey login. I have a cell phone with an entirely different number that I use for non-2FA things so if it gets compromised i'm OK. I do access that email from that phone, so I suppose i'm a bit vulnerable to targeted phone theft, but SIM swapping shouldn't be a problem, I don't think? In the opinion of HN is this the most secure way to do it while still allowing me to use services that force SMS based 2FA (almost everything) ? Is there a better way?
