How would they get past the other factor, the password?
If you’re gonna say “SMS can be used to reset the password” then it starts to sound like you’re complaining about insecure password reset processes, not 2FA.
Password are routinely stolen, then bought and sold on hackers’ marketplaces. That’s how.
Yes, but that argument can be made against TOTP too.
SMS 2FA is less secure than TOTP, but still better than no second factor, since most criminals with access to a password database aren’t able to take over your phone number (on a large scale).
With most services allowing some kind of password reset over SMS, I also prefer no 2FA over SMS 2FA. I already lost an account because I changed my number.
Some people really don’t understand layered security.
Too many of them are programmers.
