I don’t know if I’m opening a can of worms here, and I’m still trying to backtrack a lot of history where I was tuning everything out. I keep seeing random swipes at Signal (or the representatives (?)), and I was wondering whether they are founded or just lies.Is it another situation like Lemmy where we just “take the technology and move on”? Thanks!

my problem with signal is that they have a hard requirement to use a phone number for signup and that they don’t want to do anything about federation or messenger intercompatibility.
Their resoning is that they only trust themself to keep the meta data safe and so need you. Leaves a little bit of a sour tast in my mouth that they don’t even give their users the option to opt into federation.

Their reasoning is that they only trust themself to keep the meta data safe and so need you.
That’s not their reasoning. Their reasoning is that it’s much harder to evolve the protocol in a decentralized context than a centralized one. It’s not that they only trust themselves with your metadata, it’s that they can improve the protocol much faster in order to get rid of most metadata.
They have been able to deploy a ton of protocol updates with regards to minimizing the amount of metadata anyone has access to (including them), while other decentralized alternatives have essentially been stuck in limbo for a while:
- Secure Value recovery
- Groups V2
- Sealed sender
- Usernames
- Post quantum resistance
On the other hand, Matrix, XMPP and email are very leaky with regards to metadata. I’m not going into email because that’s pretty documented, but here it is for matrix:
- Message reactions are not encrypted
- Group membership are not encrypted (which lead to attacks)
- Profile pic and Name are public (visible by everyone even people with whom you don’t have any contact)
This is a good comparison of messengers here:
https://eylenburg.github.io/im_comparison.htm
Btw, an imprtant aspect of privacy is how metadata are handled/leaked. Signal trues to minimize metadata leak to near zero (there are some other messengers that do that, like simplex)
This comparison makes some questionnable choices. It puts the presence of a web client as green, when actually this breaks the thread model of end-to-end encryption.
Signal is an open-source privacy-focused end-to-end encrypted texting platform (so competing with SMS, WhatsApp, iMessage, Telegram, and similar). It’s developed by a donation-funded non-profit organization.
Signal is quite good compared to the competition, but it faces a lot of scrutiny because they make big promises about privacy and security so the people who care will really get into the details on that. Also IIRC there was a period when one of their competitors was trying to slander them more or less.
In general there’s nothing wrong with Signal and it’s quite a good option. If you really care about the privacy details you can always host your own instance (but that would require you to convince your friends to use your instance … it’s not federated).
The deal is that they run their program in a very transparent and wherever possible verifiable way.
More details here: https://lemmy.world/comment/14775870Different people don’t like it for different reasons. Some people don’t like it because they think it has CIA financial backing (nope), and some people don’t like it because it requires your phone number, therefore it is not private (the privacy it provides is more than sufficient for anyone not actively being persecuted by a Five Eyes state), and some people don’t like it because it feels corporate (it’s a 501c3 nonprofit, and how corporate it feels is subjective).
Accurate. And if you are being targeted by 5 eyes, your phone is probably fucked, one app vs another probably won’t make a difference
If you ARE targeted by 5 eyes, you’d probably want to not be using your phone for communications, but Signal sorta requires you to, even if there’s a desktop client.
However, I don’t presume to know what would be the best option. SimpleX maybe, as the servers don’t keep messages? Otherwise, I use Matrix because it’s a lot more common and very easy to set up your own homeserver. However, again, if I had to hide something from a 5 eyes threat actor, they’d just find some vulnerability in my server config or, hell, maybe they can somehow sneakily get root access through the VPS provider itself, as I’m not hosting on my own hardware.
Honestly, meeting in person might be the most private solution if you’ve got that kind of a threat model.
Signal doesn’t keep messages on their servers either. The only data they have on you is your phone number and the unix time you made your account in.
How do you know that?
It’s what happens in the publicized source code, yes, but how do you know that’s what’s running in their servers? How do you know that all requests aren’t saved?
Luckily Signal has e2ee and client side code is easy to verify, so they’d only have access to encrypted messages anyway, but if you’re talking state level actors of the highest caliber, they might be able to crack Signal’s encryption eventually.
Look, I’ll agree that Signal is probably secure enough. It’s definitely secure enough for me, I only run Matrix as a hobby because I like decentralization, my Matrix server is probably less secure than Signal. But I’m just saying we can never know for sure what code is running in THEIR servers, therefore we can never trust is 100%.
https://signal.org/bigbrother/ Its all they claim to have at least.
And I hope for sure that they’re never quietly forced to change that.
But again, if there were 3 letter agencies and gag orders involved with Signal, they probably wouldn’t give regular law enforcement or courts any of the data they have.
Really, my only problem is that with a centralized service, there’s no way to ever know for sure. There’s luckily no evidence of anything nefarious happening at least.
And some people don’t like it because it used to handle SMS on Android, and they removed that feature for security reasons.
This was such a dumb decision
That was a pretty wild decision
Handling SMS and handling secure/encrypted messages could’ve made people think they communicate securely while relying on text messages instead.
Not handling SMS fixes this source of confusion and I applaud their decision.There were ways to make it clear that it was insecure that didn’t alienate an arguable majority of their casual userbase.
The problem is that most people don’t want multiple text apps, they just want one. I had gotten a number of people using signal, and it was secure when we talked, but when signal dropped SMS, almost every one of them stopped using it, so then none of their conversations were secure.
Yeah, the never-ending weighting between convenience and security.
But are you going to tell me that those people don’t have Whatsapp, Threema, Telegram or any other IM installed and just use plain SMS instead?Yep, just the default messaging app on their phone.
If only the was some indicator for unsecure messages, such as a grey send button and an open padlock. 🙄
I think the number of people who care deeply about privacy and cannot tell the difference between an sms or signal message is minimal. There were plenty of ways signal could have highlighted DANGER UNSECURE CHANNEL if they had wanted to, or made it an off-by-default option, rather than drop SMS entirely. For myself and many other people it meant that family members dropped Signal rather than have an extra messaging app, and so I’m still stuck with WhatsApp on my phone…
I think having an unlocked symbol for standard SMS would’ve helped that…
And you seriously think most people would look at and act on such an icon instead of just ignoring it?
Or just accept that not everyone will be having a secure conversation every time at first, but more will be secured as more and more people like me convince our family members to use it and eventually we transition everyone away from SMS?
No, of course not, why would we build a critical mass of users like that?
Since they removed SMS support almost my entire family and my friends uninstalled signal, except a few who keep it to talk to me, and my half dozen friends privacy-conscious enough to care. Dozens of people, down to eight if you don’t count me, in my circles alone. Objectively, removing SMS support harmed Signal’s popularity and made everyone less secure. The argument for why they did it was at best myopic and also, in my opinion, utter bullshit.
It was very unpopular with my girlfriend, who I had just gotten into using Signal a few months prior.
This might be offtopic but:
Fun Fact, you can use an open source app like Secure Space Encryptor (SSE) (on iOS its called “Paranoia Text Encryption”) to convert any string of text into a encrypted ciphertext, and you can then copy-paste that ciphertext and send it over any medium, like SMS, without the internet. (Most encrypted messaging apps require you have to have internet AFIAK, so people without a data plan is fucked, but with SSE, you can just send ciphertext over SMS) Its not intergrated with SMS, so you’ll have to type plaintext in the app then copy paste the ciphertext it spits out.
Or you can also PGP over SMS
I remember when Signal used to intergrate with SMS, and I kinda liked that more than the Signal today where you have to use the internet and go through their servers.
Getting people to switch to Signal was difficult in the first place Imagine trying to get them to use PGP lmao
xD
This is how TextSecure worked before it was renamed to Signal and removed SMS support.
there’s oversec on f-droid that can almost automate this
This got me thinking that it should also be possible to automate on iOS with Shortcuts….
Oh yea that overlay thingy, kinda glitchy last time I tried it. If someone is techy enough to manage that clunkiness, then they probably can figure out how to manually copy-paste with SSE.
Btw, these apps are for nerds, not for the average person. No one irl that I know (besides me) would be willing to use either app.
Some people don’t like that they attached a crypto wallet to the app. I couldn’t care less and use the messenger daily!
I don’t care or use it either, but I haven’t seen a single use case for that wallet nor mobilecoins. Does people actually use it and for what?
Its honestly very hidden away, I had to dig around in settings to find it.
My friend sent me some MOB coins mainly because he could attach messages with the transactions. So no idea what it’s really used for
I don’t think I’ve ever seen people say it has CIA financial backing. It did however until only a couple of years ago have strong ties to the State Department’s Open Tech Fund (from the same financial envelope that brings you RFA/RFE/VOA).
The main developer of Lemmy seems to think there’s a solid connection. I’m not jumping in that fight, I got no dog in that fight, I don’t have that kind of threat model.

However, considering he’s openly Marxist, he may be just slightly biased.
I suspect OP of this post actually saw the recent /c/Privacy thread over at lemmy.ml where Dessalines was proselytizing against Signal while not seeming to have a problem with SimpleX chat being funded by a group of Venture Capital investors, including Jack Dorsey.
Openly Marxist is just the start of it. Dude is utterly unhinged, so his theories don’t mean a lot to me unless they’re backed by evidence.
Nothing in there is incorrect.
I understand why, but I get annoyed that I can’t integrate it into ferdium with my other things like discord, e-mail and calendar.
It’s mostly minor shit, it’s better than the alternatives unless you self-host (which has a boatload of other issues).
The thing is I have yet to see any reasonable alternatives.
Threema is the closest but it’s not free-of-charge, so a non-starter for most of my friends.
The others are controlled by Russia (telegram) or Meta. What else even is viable?
Session, an Australian fork of Signal with onion routing and no phone number requirement, seems promising.
Session disables forward secrecy for no reason.
Personally, I assume it’s a honeypot.
And it’s Australian - which means all it’s staff are obligated by law to place backdoors into their software for essentially whoever asks provided they flash a badge. If you don’t, it’s a one way trip to gaol.
If you trigger a canary in the coalmine somewhere, gaol.
Speaking as one - don’t trust Australians with your security. Ever.
This also disables notification text which is a good choice IMHO as those can be provided by Apple/Google to law enforcement
Didn’t know it was a Signal fork, interesting
I’m trying to move my family to Matrix with a self hosted server. It’s not easy though because of bugs in it.
How does simplex compare?
