Someone needs to design a super dumb and robust system where I can safely store all my keys on all devices I use an account. The fact that whatsapp, signal and other platforms tend to have a primary device for keys is bonkers to me. A primary device that can randomly die, get stolen or fall in a lake.
I have lost chat histories more times than I can remember, and I have to be extra diligent about this these days.
I don’t even want to think about pgp when I have to manually take care of this problem. Not because of my own skills, but because I could never make it reliable for my family and friends on their side.
- wmf 10mo agoApple/Google passkeys.
- throwaway82931 10mo agoIndeed, passkeys would seem to represent a step forward from single-device to single-account.
- lazide 10mo agoPasskeys are often stored/locked per device?
- ho_schi 10mo agoTwo problems: Apple. And Google.
- UltraSane 10mo agoBut then Apple or Google can control your access to any account that uses those passkeys. We need a protocol where I can store the same passkey on multiple cloud providers
- AnonC 10mo ago> I have lost chat histories more times than I can remember, and I have to be extra diligent about this these days. As per Signal’s diehard proponents, losing chat history is a feature, not a bug (I’m not being facetious when saying this, and you can see comments of this kind in Signal related threads here). Edited to add: I don’t agree with that premise and have long disliked losing chat history.
- laserbeam 10mo agoI know you are not being facetious. My problem is random Joe on the street sees it as a bug. He really does care more about actually being able to talk with his wife than Signal’s mathematically correct principles. He needs it to be reliable first, secure second.
- AnonC 10mo agoGP here. I agree. I should’ve stated that I don’t like losing chat history and have seen that as a problem with Signal. I have edited my previous comment to reflect that I don’t like losing chat history.
- IlikeKitties 10mo ago> He needs it to be reliable first, secure second. Than he should use something else. I need signal to be secure first, second and third and reliable in edge cases like this a distant number.
- golem14 10mo agoYeah, but if use proton for everything else and signal only for my secret world domination plans, traffic analysis will be so much easier…
- pcthrowaway 10mo agoCongrats on not being one of the people concerned about being targeted by their government, now or in the future. Hundreds of millions are not so lucky.
- integralid 10mo ago(i am a security person who prioritizes security over usability but) you missed the point a bit. If a privacy program is used only by people that have something to hide it turns into a smoking gun. If you care about being targeted by government you should really hope regular people use signal a lot, because government absolutely has (or can procure) a list of people that use signal.
- Helmut10001 10mo agoI set up automatic backups of WhatsApp to my self-hosted Nextcloud once. Since you need 'tested backups', I tried to decrypt these WhatsApp backups independent of my phone, but this was not possible. You need the original device. There are some hacks online, but they are always out of date. I am tending now to running Mautrix Whatsapp bridge and backing up my data through this.
- laserbeam 10mo agoAsk yourself. If you want things to be encrypted by default in the world, would a florist be able to self host nextcloud?
- Helmut10001 10mo agoAgreed. I am still unhappy, but perhaps this is entirely my problem.
- nine_k 10mo agoThis is a difference in the threat model. Signal's threat model is that everything around you is hostile to you, except the parties you interact with. You are an undercover rebel in a totalitarian sect which would sacrifice you to Cthulhu if they see your chat history. Losing it is much better than disclosing it. Your threat model is likely random black hat hackers who would try to get into your communication channels and dig some dirt to blackmail you, or to impersonate you to scam your grandmother out of several thousand dollars. Signal protects quite well against it. But the chance of this happening even in an unencrypted channel is low enough. You don't mind making the security posture somehow weaker, but preserve the possibility to restore your chat history if your secure device is lost or destroyed. I suppose the problem could be solved by an encrypted backup with a long key which you keep on a piece of paper in your wallet, and / or in a bank in a safe deposit box. Ideally it would be in the format that the `age` utility supports. But there is no way around that paper with the long code. If this code is stored on your device, and can be copied, it will be copied by some exploit. No matter how inconspicuous a backdoor you are making, somebody will find it and sneak into it. Should it happen in a publicized case, the public opinion will be "XYZ is insecure, run away from it!".
- marcosdumay 10mo ago> If this code is stored on your device, and can be copied, it will be copied by some exploit. Yeah... We really need some key-management hardware where the secrets can be copied by some channel that is not the primary one. This used to be more common, before the IT companies started pushing everything into the cloud. I have recently started to see computer boards with write protection for the UEFI data, what is a related thing that also did go away because mostly of Microsoft. So, maybe things are changing back.
- tonyhart7 10mo agomy proposal devices is like yubikey but instead of yubikey hardware in place like USB devices form its in the form of ring or bracelet, its small enough and can be carried everywhere with you all the time its use NFC like technology, it works without battery, fast and "secure enough" for 99% of people what if the device is stolen???? we can add authorization like biometric (fingerprint etc) while touching devices so it can be sure the real owner is "giving" auth
- BaconVonPork 10mo agoThe problem is not a personal hardware security module, as you noted we have them. The problem is that people want redundancy that undermines the point. If you can easily have a copy of your ring just in case, how do you know who has done that process and watches you all the time? Biometrics sounds like a solution yet they are implemented as a cosmetic security layer and this situation is pointless to fix since we leave them everywhere we go.
- tonyhart7 10mo agoif people want to copy then let them copy -how is that secure???? we would let only 1 device active at a time if you think secure enclave with Biometric security is "weak" then no one is secure if you think combination of (fingerprint,DNA,blood variance,retina, star time + position, mental memory etc) is not enough then no one is enough (we are assuming this is future where we can access all this technology) << this is important point here also if this is not enough, ppffttt (I dont want to go here) Neuralink device that lives under your skin
- pmontra 10mo agoSo, the requirement is a system to store all your keys and that it can be duplicated as many times you wish. It looks like a local password manager, let's say keepass. I use it and have copies of the encrypted db on every device of mine, plus the client to access the passwords. I don't know if it qualifies for dumbness but it feels pretty robust. It survived the fall into the lake test (a river in my case.) But I see every customer of mine using web based password managers, because they want to share and update passwords with all their team. Of course those password managers can use E2E encryption and many do, but my instinct is that if you are using somebody's else service for your data, you can be locked out from your data. Anyway, it's the concept of having many passwords and having to manage them that's not dumb enough. The most that people do is letting the browser store and complete passwords. The password can be the same 1234pass on every single site.
- WolfeReader 10mo agoWeb-based password manager user here! It's worth noting that Bitwarden and 1Password (probably all the others too) let you export all of your data into an encrypted archive, so anyone who does this periodically won't be "locked out". (Naturally, this requires extra effort on the users' part, so who knows how many are actually using this ability.)
- UltraSane 10mo agoEven better I run vaultwarden on the cheapest AWS instance using tailscale. This lets me make S3 backups of the disk easily.

- Ferret7446 10mo agoMaybe I'm old but I never expect chat history to be a permanent thing. It's like talking to someone, it should be ephemeral. If you need a record, use email. Recording and archiving every conversation with someone is just weird. Thanks for listening, now you dang kids can get off my lawn
- UltraSane 10mo agoThere is absolutely no reason not to store and index text chats since they are so little data.
