> Printed/saved backup codes are still an option Vast majority of users don't bother with such complexities. SMS is the easiest minimum entry barrier to 2FA. It is better than having just passwords.

> It is better than having just passwords. That is false. Many incidents have been widely reported where huge names, who certainly could afford even a $50 hardware token to protect their reputation/brand, were 'hacked' because they thought SMS 2FA protected them - and it didn't. Even with services which do also offer TOTP or U2F etc.

It is better. It’s just not perfect.

Agreed. Users have it in their power not to use services that require a phone number for SMS verifcation.

More and more services are supporting - or worse, requiring - SMS-based or phone-based 2FA. Moreover, people frequently do not "have it in their power" not to use a particular service. For example, I decided to log in to Fidelity the other day, since I still have a 401(k) with them from an old employer who did matching. They require call or SMS 2FA. And you could draw even stronger requirements to various government…

Most places offer an alternative. Especially institutions that are not FAANG-types, like government services and heavily regulated ones like banks. I am a U.S. citizen and have never encountered a service that didn't have alternatives to using a smart phone. Are you saying that Fidelity would not have mailed you a statement?

A complaint can be registered with the company, regulators, and/or politicians. Switch to another provider if possible. I know it's not always easy, I'm not perfect in this regard. But if nobody does anything, nothing will change. Are you telling those of us who feel this way to give up?

Reminder: SMS 2FA adds only a negligible amount of security, if your company does 2FA via SMS you're doing nothing more than lulling your users into a false sense of security. Don't do it. Support proper 2FA. (And while you're at it, allow your users to decide how much they care about their account. Don't make the decision for them.)

That’s great until your users lose/break their phone and have no backups for their 2FA codes. “Sorry you’re locked out forever, good luck lol” Is not a response you can give to them.

I use Authy app which performs encrypted backups to the cloud and verifies regularly that I can still remember the passphrase. I have never lost a TOTP token this way.

In Australia it's mandated you're sent a message before rerouting or migrating to another provider. Surprised this isn't enforced in the other countries, it costs next to nothing to implement and is just an additional step in the account migration process. I'd love to see companies allow for opt in additional security measures, like banks or telco's calling me - having a verbal password to confirm things, that level…

I tried to get T-Mobile to stop giving my location to anyone that hits their APIs with a 'Yes I have permission' flag set. There's no opt-out for it, and no enforcement of the permission requirement. Their support had me snail mail a letter to some PO box. I never got a response. And now they're going to start outright selling their customer activity after forcibly un-opt-outing* everyone who opted out in their priva…

T-Mobile has such shitty IT, infrastructure, and security practices.

My last experience with them caused me to switch away from them permanently. I switched away from them after getting SIM jacked, with real money stolen from me. Happened exactly like in this article[0].

Another incident happened where my online account was merged with someone else's in California (I'm in Texas). Our billing information was merged, with the others paying for the whole account. I couldn't make changes online- only after sitting on hold and explaining what happened was I able to get the whole situation unfucked, but there's no telling what amount of my data still lives in that other account.

Come to think of it, my first experience with T-Mobile was as a Radio Shack employee, circa 2010. When a customer came to the store to pay their T-Mobile bill with cash, if I took too long to enter all the data into their awful online portal the money would sometimes go to a completely different person's account. Many hours were spent on the phone with the local and regional rep resolving multiple instances of this happening.

A lot of times SMS 2FA significantly degrade security with services that allows you to "recover" access to your account via SMS.

But then that's not actually 2FA then, is it?

I would disagree. Obviously, there are better approaches, but consider basic password auth on desktop, that is easily exploitable en masse by botnets. if you add 2FA via SMS, you would need to exploit both devices (or attack SS7, transfer number or some other trick) and match infos from these devices. Can be done in targetted attack, but harder in en masse botnet attacks.

Saying something is illegal and expecting everyone to follow the law is just pinky-swearing.

Yeah! Why have laws anyways? Every law will be broken sooner or later and it’s not like we have institutions tasked with enforcing laws. /s

I'm under the assumption that wiretapping to create evidence is illegal, but wiretapping to get a warrant probably happens all the time. (AKA Judge and Police officer listen to illegally captured audio - Judge approves official warrant to make future recordings legal)

T-Mobile has such bad practices -- about 6 years ago they gave my phone number out as a temporary number to someone else. I don't know how their infrastructure is set up, but both me and this other guy had the same number for a time. Incoming calls would be routed to the phone that called out last. At one point I was able to talk to the other guy by using my wife's phone to call my own number. T-Mobile claimed that what was happening was impossible, so I filed a complaint with the FCC and switched my phone service. By the time T-Mobile responded to the complaint (by saying nothing was wrong), I had long since switched providers, so I didn't pursue the matter further. Huge annoyance though.
