SMS 2FA is better than nothing if, and only if, you don't allow password resetting by owning the SMS.

TOTP is better than SMS in that it's secure with fewer caveats.

Why am I being downvoted?

I'm literally willing to volunteer days of my time, unpaid, to prevent SMS 2FA in favor of something more secure (i.e. TOTP).

I can't speak for all of those who downvoted you, but the comment you responded to mentioned how SMS based 2FA would be better than what they do today (i.e. nothing).

This is a fact. SMS 2FA, regardless of how bad it is, is still another hurdle an attacker would have to overcome. An additional hurdle, no matter how small, is still better than nothing at all. Therefore the assertion that SMS 2FA would be better than what they do today is simply an irrefutable fact.

If you left off the "Oh god please no." portion of your comment, you may not have been downvoted.

Not really. It means I now have to prove prove to the site that I got my sim hacked and has to go to a ton of trouble getting my phone number back.

Seriously auth over sms should not only be froned upon, but illegal. It is a nice cover you ass for the site that does it, but if you do 2f any way that is not using a uf2 physical token you should not be allowed near a computer.
