Personally, I think the fear of using SMS is overblown. The first vulnerability (SIM swap) would be readily detected because your own phone would stop working on your number. The 2nd vulnerability (SMS intercept) would really depend on a very knowledgeable hacker targeting you specifically. For something like cameras, I’m just not worried about this. Having SMS 2FA in place would be so much better than nothing and make it likely that any hacker will pursue and easier target.
The article itself even says:
Remember, using two-factor authentication via SMS is better than leaving 2FA disabled. And it’s probably unlikely that you will become a victim.
