A huge security problem is websites using SMS to implement 2FA, or having a phone-based "fallback" for when I lose my 2FA token. I see this as a problem 1Password could solve for its users. Specifically:
1. 1Password would offer a paid service where you get a designed phone number that you provide to websites that use SMS 2FA/Fallback.
2. 1Password would pinky-swear promise that this number is perma-linked to your account and can never be ported anywhere never ever period.
3. When logging in to this website, the service would send an SMS that 1Password receives and forwards to the 1Password client
4. The 1Password client receives the code and enters it, making the user experience identical to using a token-based OTP.
And for anyone looking for an interim solution: you can use a designated Google Voice account for this purpose. I am told it is hard or impossible to social engineer Google into porting a number out, and at the very least this designated number is much harder to know than my everyday phone number.
