  • I prefer security keys. At work I use a yubikey, and I have Google’s security keys for my personal stuff. I tend to use totp as a backup.

    For everything not banking, it’s great, I agree. I still prefer my security keys to everything. It’s hard to duplicate a digital key when it only exists on protected storage on a physical device, where that key never exists outside of that physical device.

    In case anyone doesn’t know: FIDO works using a pair of asymmetric digital keys, the public key is sent to the remote site, and only the private key can decrypt anything encrypted by the public key. So a challenge (usually some mathematical calculation, not sure), is encrypted by the site/service that is handling the login, it sends over the encrypted request, which is passed, in it’s entirety to the fob. The fob requires a physical activation to process the challenge (usually a touch, but some require a fingerprint). The challenge is then decrypted, processed, the response is encrypted, and sent to the site for login, which decrypts the response with the public key, and compares the result to the result of the challenge that was sent.

    There’s no part of this that can really be compromised. An eavesdropper can obtain the encrypted challenge (unable to be decrypted in any reasonable manner), and the response/public key… The public key isn’t useful, and the response is only valid for that specific login because there are aspects of the challenge that are unique per login.

    All information in flight is unreadable nonsense. The only unique information to the key that is sent anywhere is the public key, which is supposed to be public.

    Totp has the vulnerability of needing to relay the seed, usually by QR code. The only vulnerability there is when you set it up and the seed is shared to you, it can be intercepted. If that seed is stored anywhere that becomes compromised, then it becomes meaningless. It can be mined from an authenticator, or captured in flight.

    Both of these are better than alternatives. Email/sms codes can be intercepted, either by an administrator or by an internet relay, or by sim duplication, etc. You know that already.

    I don’t hate totp, I just recognize the faults in it.

    There’s problems with physical security keys too, mainly in the fact that, if you lose the fob, you’re screwed. So it’s recommended to have a backup. Either in the form of a second fob, which is setup for all the same accounts which is stored securely, or in the form of another authentication method like totp.

    Personally, I use a backup FIDO key for my accounts whenever possible. I also have a password manager that can store my totp so everything is in a single vault. If the vault is compromised then I’m screwed though… 90% of my accounts use a password reset email which is not stored in my vault. Only two things are not in my manager: that recovery email login (secured by my Fido key) and my bank (obviously also the vault login).

    At work, I use the yubikey for everything that supports it, with totp as backup in my work’s duo authenticator account (duo is also setup to use my yubikey). So it’s all Fido/totp.

    The only service I really want to use my security keys with that doesn’t support it, is my bank account… I suppose, also my government stuff, but almost all of that is informational. I can’t really make changes to my government stuff from their webpages. It’s generally just the government telling me things about my tax returns and whatnot (all SMS secured).

    I hate the trend of companies requiring an app for 2FA… Something that’s not totp, but similar. You have a specific authenticator app for a single service on your phone only and it’s not great… Obvious examples include steam and Blizzard. Fuck that. I hate it. Go away. Give me normal MFA options… Dick.

    I’ve ranted enough. Back to work for me.

    Your story reminds me of something that my bank started doing. I got a robocall about something to do with my credit card, and the voice said to verify using x and y using my keypad, I think it was day/month/year of birth or something and I immediately noped out of the call. I hit all the wrong buttons until it got me to a person and I ripped them apart, and their supervisor for basically training their userbase to answer security questions given by an automatic voice on the other end of the line with no way to verify who is calling.

    You can spoof your caller ID, you can get a text to speech robocall bot with DTMF recognition and just spam call a whole area where the bank operates and gather a bunch of personal information because it sounds just like the bank and there’s no way to prove who called.

    What a crock of shit. It’s a security nightmare.

    I did call my bank after at a known valid number, verified them as they verified me, and there was something going on, so the call was legit, and totally unacceptable.

    These clowns want us to trust them completely, and give us no reason to do so, but they want us to bend over backwards to validate ourselves. Fuck that.







  • I just don’t understand how he thought this was something he should put on a public forum.

    Maybe a snide/sarcastic remark along friends, sure… It’s still not in good taste, but at least it’s contained to people you should trust.

    But… On Twitter?

    Why?

    Making rude/inappropriate comments, however, is very on-brand for Elon.

    There’s a whole subset of idiots that believe that you need to expose yourself to harmful shit to have a strong immune system. (See: all the people licking toilets and crap during lockdown)

    There’s some credible science to it, in the way that, an immunization is literally putting “harmful” stuff in you to train your immune system. This is known science that I should be able to mostly hand wave around since most people already know this. Immunizations are usually focusing on a key indicator, eg, for COVID, it’s the protein on the outside of the vital cell wall (all the spiky bits in the illustrations) or whatever… I’m no scientist. For other viruses and bacteria, it’s a deactivated version of the virus… It’s essentially “dead” for all intents and purposes. It just resembles the virus so closely that it effectively trains your immune system to recognize it.

    With all that being said, not all bacteria and viruses are something we can develop a natural immunity to, partly because some of them just kill us, partly because there’s something that is preventing it. Again I’m not a scientist.

    Regardless, these idiots think that by exposing yourself to “natural” viruses and bacteria, you can strengthen your immune system. Bluntly, it’s possible to do that, and why the fuck would you want to do it that way? It’s literally a randomized version of a science we already have that’s tried, tested, and proven effective, called immunizations. With immunizations, you get all the benefits of surviving the horrors of some of the most nasty viruses and bacteria out there, without suffering through what those viruses and bacteria are going to do to you.

    The whole thing is stupid.

    If anyone argues about “good” bacteria, tell them to eat yogurt. FFS.
