You know google authenticator doesn't matter right? You know you could always copy your totp seeds since day one regardless of which auth app or it's features or limits right? You know that a broken device does not matter at all, because you have other copies of your seeds just like the passwords, right?
When I said they are just another password, I was neither lying nor in error. I presume you can think of all the infinite ways that you would keep copies of a password so that when your phone or laptop with keepassxc on it breaks, you still have other copies you can use. Well when I say just like a password, that's what I mean. It's just another secret you can keep anywhere, copy 50 times in different password managers or encrypted files, print on paper and stick in a safe, whatever.
Even if some particular auth app does not provide any sort of manual export function (I think google auth did have an export function even before the recent cloud backup, but let's assume it didn't), you can still just save the original number the first time you get it from a qr code or a link. You just had to know that that's what those qr codes are doing. They aren't single-use, they are nothing more than a random secret which you can keep andbcopy and re-use forever, exactly the same as a password. You can copy that number into any password manager or plain file or whatever you want just like a password, and then use it to set up the same totp on 20 different apps on 20 different devices, all working at the same time, all generating valid totp codes at the same time, destroy them all, buy a new phone, retrieve any one of your backup keepass files or printouts, and enter them into a fresh app on a fresh phone and get all your totp fully working again. You are no more locked out than by having to reinstall a password manager app and access some copy of your password db to regain the ordinary passwords.
The only difference from a password is, the secret is not sent over the wire when you use it, something derived from it is.
Google authenticators particular built in cloud copy, or lack of, doesn't matter at all, and frankly I would not actually use that particular feature or that particular app. There are lots of totp apps on all platforms and they all work the same way, you enter the secret give it a name like your bank or whatever, select which algorithm (it's always the default, you never have to select anything) and instantly the app starts generating valid totp codes for that account the same as your lost device.
Aside from saving the actual seed, let's say you don't have the original qr code any more (you didn't print it or screenshot it or right-click save image?) there is yet another emergency recovery which is the 10 or 12 recovery passwords that every site gives you when you first set up totp. You were told to keep those. They are special single-use passwords that get you in without totp, but each one can only be used once. So, you are a complete space case and somehow don't have any other copiesbof your seeds in any form, including not even simple printouts or screenshots of the original qr code, STILL no problem. You just burn one of your 12 single-use emergency codes, log in, disable and re-enable totp on that site, get a new qr code and a new set of emergency codes. Your old totp seed and old emergency codes no longer work so thow those out. This time, not only keep the emergency codes, also keep the qr code, or more practical, just keep the seed value in the qr code. It's right there in the url in the qr code. Sometimes they even display the seed value itself in plain text so that you can cut & paste it somewhere, like into a field in keepass etc.
In fact keepass apps on all platforms also will not only store the seed value but display the current totp for it just like a totp app does. But a totp app is a more convenient.
And for proper security, you technically shouldn't store both the password and the totp seed for an account in the same place, so that if someone gains access to one, they don't gain access to both. That's inconvenient but has to be said just for full correctness.
I think most sites do a completely terrible job of conveying just what totp is when you're setting it up. They tell you to scan a qr code but they kind of hide what that actually is. They DO all explain about the emergency codes but really those emergency codes are kind of stupid. If you can preserve a copy of the emergency codes, then you can just as easily preserve a copy of the seed value itself exactly the same way, and then, what's the point of a hanful of single-use emergency passwords when you can just have your normal fully functional totp seed?
Maybe one use for the emergency passwords is you could give them to different loved ones instead of your actual seed value?
Anyway if they just explained how totp basically works, and told you to keep your seed value instead of some weird emergency passwords, you wouldn't be screwed when a device breaks, and you would know it and not be worried about it.
Now, if, because of that crappy way sites obscure the process, you currently don't have your seeds in any re-usable form, and also don't have your emergency codes, well then you will be F'd when your phone breaks.
But that is fixable. Right now while it works you can log in to each totp-enabled account, and disable & reenable totp to generate new seeds, and take copies of them this time. Set them up on some other device just to see that they work. Then you will no longer have to worry about that.
My original, correct, message was perfectly short.
You don't like long full detailed explainations, and you ignore short explainations. Pick a lane!
A friend of mine a long time ago used to have a humorous classification system, that people fell into 3 groups: The clued, The clue-able, The clue-proof.
Some people already understand a thing. Some people do not understand a thing, but CAN understand it. Some people exist in a force bubble of their own intention that actively repels understanding.
I see that in your classification system an important entry is missing. The ones who disagree.
In your quest to convince me you forgot to even stop to ponder if you're right at all. And in my view, you aren't.
Perhaps the problem isn't that I don't understand you. Perhaps I understand you perfectly well but I understand even more, to realise that you're wrong :)
This is a silly thing to argue about but hey I'm silly so let's unpack your critique of the classification system
There is no 4th classification. It only speaks of understanding not agreeing.
Things that are matters of opinion may still be understood or not understood.
Whether a thing is a matter of opinion or a matter of fact, both sides of a disagreement still slot into one of those classes.
If a thing is a matter of opinion, then one of the possible states is simply that both sides of a disagreement understand the thing.
In this case, it is not a matter of opinion, and if you want to claim that I am the one who does not understand, that is certainly possible, so by all mrans, show how. What fact did I say that was not true?
Keep trying soldier. You never know. (I mean _I_ know, but you don't. As far as you know, until you go find out, I might be wrong.)
Whatever you do, don't actually go find out how how it works.
Instead, continue avoiding finding out how it works, because holy cow after you've gone this far... it's one thing to just be wrong about something, everyone always has to start out not understanding something, that's no failing, but to have no idea what you're talking about yet try to argue about it, in error the whole time..., I mean they (me) were such an insufferable ass already trying to lecture YOU, but for them (me) to turn out to have been simply correct in every single fact they spoke, without even some technicality or anything to save a little face on? Absolutely unthinkable.
Definitely better to save yourself from that by just never investigating.
My original statement was only that this is not a 2fa problem, which was and still is true.
The fact that you did not know this does not change this fact.
I acknowledged that web sites don't explain this well, even actively hide it. So it's understandable not to know this.
But I also reminded that this doesn't actually matter because you WERE also given emergency recovery passwords, and told to keep them, and told why, and how important they were.
You were never at risk of being locked out from a broken device EVEN THOUGH you didn't know about saving the seed values, UNLESS you also discarded the emergency codes, which is not a 2fa problem, it's an "I didn't follow directions" problem.
And even if all of that happened, you can still, right now, go retroactively fix it all, and get all new seed values and save them this time, as long long as your one special device happens to be working right now. It doesn't matter what features google authenticator has today, or had a year ago. It's completely and utterly irrelevant.
My premis remains correct and applicable. Your statement that 2fa places you at at risk was incorrect. You may possibly be at risk, but if so you did that to yourself, 2fa did not do that to you.
> But I also reminded that this doesn't actually matter because you WERE also given emergency recovery passwords, and told to keep them, and told why, and how important they were.
Ah yes those… the codes I must go to a public library to print, on a public computer, public network and public printer. I can't really see any problem with the security of this.
And then I must never forget where I put that very important piece of paper. Not in 10 years and after moving 3 times…
You can save a few bits of text any way you want. You can write them in pencil if you want just as a backup against google killing your google drive or something. Or just keep them in a few copies of a password manager db in a few different places. It's trivial.
What in the world is this library drama?
No one is this obtuse, so your arguments are most likely disingenuous.
But if they are sincere, then find a nephew or someone to teach you how your computer works.
Libraries? Remembering something for 10 years? Moving? Oh the humanity!
Yes, you can keep them on the same device if you choose to.
Or not. You decide how much effort you want and where you want to place the convenience vs security slider.
Yes, if you keep both factors not only on the same device but in the same password manager, then both factors essentially combine into nothing but a longer password.
I did say from the very first, that the seeds are nothing other than another password.
Except there is still at least one difference which I will say for at least the 3rd time... the totp secret is not transmitted over the wire when it is used, the password is. That is actually a significant improvement all by itself even if you do everything else the easy less secure way.
And you do not have to store the seeds the convenient less secure way. You can have them in a different password app with a different master password on the same device, or on seperate devices, or in seperate physical forms. You can store them any way you want, securely, or less securely.
The point is that even while opting to do things all the very secure way, you are still not locked out of anything when a single special device breaks, because you are not limited to only keeping a single copy of the seeds or the emergency passwords in a single place like on a single device or a single piece of paper.
You are free to address any "but what about" questions you decide you care about in any way you feel like.
The only way you were ever screwed is by the fact that the first time you set up 2fa for any site, most sites don't explain the actual mechanics but just walk you through a sequence of actions to perform without telling you what they actually did, and so at the end of following those directions you ARE left with the seeds only stored in a single place. And in the particular case of Google Authenticator, stored in a more or less inaccessible place in some android sqlite file you can't even manually get to without rooting your phone probably. And were never even told about the seed value at all. You were given those emergency passwords instead.
That does leave you with a single precious drvice that must not break or be lost. But the problem is only a combination of those bad directions given by websites, and the limitations of one particular totp app when that app didn't happen to display or export or cloud-backup the seeds until recently.
Even now Googles answer is a crap answer, because Google can see the codes unencrypted on their server, and Google can kill your entire gooogle account at sny time and you lose everything, email, drive , everything, instantly, no human to argue with. That is why I said even today I still would not use Google Authenticator for totp.
Except even in that one worst case, you still had the emergency passwords, which you were always free to keep in whatever way works for you. There is no single thing you must or must not do, there is only what kinds of problems are the worst problems for you.
Example: if what you are most concerned about is someone else getting ahold of a copy of those emergency passwords, then you want to have very few copies of them and they should be off-line and inconvenient to access. IE a printed hard copy in a safe deposit box in switzerland.
If what you are most concerned about is accidentally destroying your life savings by losing the password and the investment site has no further way to let you prove your ownership, then keep 10 copies in 10 different physical forms and places so that no matter what happens, you will always be able to access at least one of them. One on goggle drive, one on someone else's google drive in case yours is killed, one on onedrive, one on paper at home, one on paper in your wallet, one on your previous phonr that you don't use but still works, etc etc.
You pick whichever is your biggest priority, and address that need however you want, from pure convenience to pure security and all possible points in between. The convenient way has security downsides. The secure way has convenience downsides. But you are not forced to live with the downsides of either the convenient way or the secure way.
