SMS isn’t even secure. Mitm, social engineering, straight up theft, and more are all ways around it. It should never have been implemented, but especially not when totp exists.
What I despise most in when SMS is not just optional but forced upon me as "backup" to TOTP. "Lost your authenticator app? Send an SMS instead." How about no?
I don’t believe I’ve run into that, but yeah it completely misses the point of totp. Hell, I’d prefer a lockout over SMS backup in most cases, my totp authentication has multiple encrypted backups.
Especially because you can just backup authenticator to the pendrive in encrypted form. I don't care I loose my phone, that's exactly the reason authenticator is better.
Dude.
My wife's phone started acting up the other day. It would keep losing cell service and even when it showed a signal, it still would only work on wifi.
That happened a few hours after I ported my phone number (on the same family plan) to another carrier. So naturally, I thought the issue was with the carrier.
Since I planned on porting her number out to my new carrier anyway, I didn't want to troubleshoot.
Well, get to the new carrier and it's still not working. Go through the whole process of resetting network settings, and then eventually deleting the esim.
New carrier, though, needs you to receive a text message before they send the esim.
Naturally, with the esim deleted, it couldn't receive text messages.
Her issue did end up being her phone. Even after the port went through in full, it was still hit-or-miss with cell service. Worked on wifi though.
I've heard people in the US still use SMS to communicate with eachother. Fucking crazy.
Only when iPhone users need to send a message to literally anyone else.
Inertia and ease of use are powerful.
SMS "just works" and works for everyone here.
While I would like the new fancy features. At least RCS is bringing some and is seamlessly integrated.
Bonus I have 10+ years of txt history and can scroll/search to find something. And since my phone is Google (I know evil) I can access it all from the desktop seamlessly in one window.

uhhh that's not some unique american thing lol, that's how people here in sweden communicate too
Barely anyone cares what specific protocol is being used, they just care about what app they have to use and who they can reach, and if anyone isn't using a normal sms app they're generally using facebook messenger or imessages both of which support sms fallback and thus their users don't even know there's a difference half the time.

At least it isn't email or SMS MFA.
Or email OFA. Burger King, Popeyes (I know they are the same company), and just a bit ago, BuyMeACoffee. They let you enter a password; fuck if I know what their requirements are. No tooltip, no failure text. 60 char with special chars? Nope. (a few moments later) 20 chars with no special chars? Nope. Fuck it, let's try 2FA. Get seed, generate code, go to setup verification page (on phone), first box, paste. ONLY THE FIRST NUMBER PASTES AND MY KEYBOARD CLOSES. SCREAMS
(only factor authentication)
Nothing compared to BOFA, which is arguably even worse and a lot more stupid
For those who don't know, the BofA app clears the username and password fields every time you switch to a different app, completely thwarting the use of password managers because Bank of America is apparently Hell-bent on forcing everyone to have easily-typed (and therefore easily-brute-forced) passwords.
Android has password managers with keyboard app integration so you can paste both fields from the keyboard itself
I use Keepass2Android and it's own keyboard app for this. I switch active keyboard app when the login field shows up to paste and then switch back to my normal keyboard after

I agree with this sentiment. Steam notably falls into the third category, while otherwise being pretty good.
But I'm quite disgusted now seeing an image of a Yubikey for the first time. I've heard so many good things about them that it's a major disappointment to see now that they use that awful noncomplaint shape of USB plug.
There are two very important reasons for the metal shield around USB plugs: 1. For ESD protection, and 2. to hold the receptacle's tongue in place and prevent it from bending away and losing contact. Every USB device I've owned that was a flat plug (like this Yubikey image in this post) has within a month deformed the USB receptacle it's plugged into to the point that the device no longer works in that port. Compliant USB devices still work in that port's deformed receptacle, because they have a correct metal shield that bends the tongue back into the correct position.
Yubikey also has usb-c versions with compliant plugs.
YubiKeys have almost every imaginable form factor these days. Here's the USB-C version without NFC:
Yeah I have an even smaller USB-C one. It sticks out less than 0.5cm from the port.
No problems with yubikeys or the receptacle they are plugged into yet.. no idea what you do while these sticks are plugged in.. doesnt seem like a major concern per the reviews
I've had my ubikey fido2 token knocking around on my keychain for about 7 years now. Scratched and beaten, works perfectly and never had a port damaged, it doesn't put enough pressure on it.
It is kind of annoying that Steam doesn't enable the usage of third-party OTP apps. To be fair, when they first implemented the feature, that wasn't widely used and plenty of websites only enabled the use of one specific OTP app like Authy or Google Authenticator. They recently added a QR code login feature, which makes sense, but that still shouldn't stop them from enabling MFA via third party OTP apps.

It is actually possible to use Aegis for Steam, that's what I do. It's a pain to setup if you're not rooted (I think you need to use an Android emulator on a computer and then export the Aegis DB to reimport it on your mobile IIRC) but it's possible. Look at https://github.com/beemdevelopment/Aegis/wiki/Adding-Steam-to-Aegis-from-Steam-Desktop-Authenticator Steam is still very welcome to go fuck themselves with their shitty app, though.

Uuuuugh. I just had this problem after dropping my phone. Can't log into the phone without the phone being logged in. Solution: disable 2fa on a logged in device. If I can disable it from another device why can't I verify it from another device? This is so broken!
my favorite instance of google MFA was when i went to log into my google account for some reason. Google hit me with the MFA, cool whatever, i'll MFA, google does the usual "heres how we do it because we give you no options because fuck you" and im like, cool, ok just gotta wait for this to work.
And then it proceeds to not work, at all. Thanks google, very cool. Fortunately, i had a secondary auth app setup so i used that, and it worked, weird how that works huh? BTW, it wasn't sms, it's googles integrated android MFA service, which as far as i can tell, is literally a fucking requirement to using MFA.
Also, i remembered again, that logging into my google account, automatically logs me into every google account i have. Yknow, because security. Anybody know how to disable that one btw? Google seems to be an endless labyrinth of options everytime i try and do something with it so.
logging into one google account does not log me into all my google accounts, as far as I know
Wait, can you eli5 why multifactor authentication (MFA) (and maybe also 2-factor authentication apps) is “fuck off” levels?
Is it privacy concerns or something bigger like more points of failure for overall security? Or smaller like not every one has/wants a smart phone?
If I read it correctly the "fuck off" level refers to some proprietary app for the selected login. The other two are standard code app and yubikey.
This is also how I read the meme. Codes are fine, tokens are fine. Your proprietary spyware app is NOT fine (Microsoft) and I hope you get fucked.
Microsoft login works just fine with any TOTP app, like Aegis. They just heavily push you toward their app.
Unless your company doesn't know wtf they're doing and it just doesn't work.

MS is fine, your average bank or broker institution though... when it's not SMS, chances are it's an "in-house" solution

I already have an authenticator app. If some service wants to force me to install their own app for their login, they are indeed welcome to fuck off.
Standard authenticator (software or hardware) are, well, standard. You can pick anything compliant and use it with any compliant service. Requiring a specific app means that you have to install yet another app, which may or may not be well made, and may or may not snoop on you, and usually will only work with one service, assuming you have a compatible device to run it to begin with.
It's more than an inconvenience; not insurmountable, but way more work than just having a standard thing that works perfectly well and is based on known and proven algorithms.

At work usually I can login without any input thanks to SSO, but occasionally it will ask for a security check. The default is to press a notification in outlook on my work phone, which I only ever use when travelling, so it's invariably off... 🙄

My brain needs to boot faster. Took me far too long to figure out that wasn't Mother Fucking Authentication, and was instead more likely Multi-Factor
