I’ve been inspecting this topic quite a lot and I’m a little confused now. So, we have reasons not to use Signal, reasons not to use Matrix, there were also some claims about Session being a fraught. Briar is mostly activists related (not very suitable for daily use), XMPP lacks good clients and suffers from fragmentation of protocol standards implementation, SimpleX is too feature-incomplete (no UnifiedPush support, big battery drain on Android, very decent desktop client without any message sync). I can’t say a lot about Threema or Wire, as I’m not very familiar with them.
So, my question is — is there any good private messenger at all? What do you think is the most acceptable option?
EDIT: In addition to my post:
All messengers have their flaws, I’m well aware of that. I was interested in hearing users’ opinions regarding these shortcomings, not in finding the perfect messenger. I may have worded my thoughts incorrectly, sorry for that.
You must log in or register to comment.
You will always find problems associated with every thing but here’s some recommandations :
For a good start, Signal and his forks (molly…)
For daily basis and better than Signal, choose SimpleX (SimpleX is only feature incomplete for the mainstream app, but in it you can send texts, voices, photos, videos, live messages, have a PP, a alias for your contacts…)
Important stuff and activism, use Briar
People say this over and over “depends on your threat model” and yet people seem to have a hard time understanding that. Your threat model is “who is your adversary and what he is willing/able to do”. Your security goal is what do you want to keep from your adversary.
As others said, if you are an activist or sth important, perhaps you might want to build a working knowledge of cryptography yourself. If you just want META not being able to see your NSFW chat with your romantic partner Signal might be more than enough. In fact, people way more relevant than me also suggest that Signal is good even for bounty hunter vulnerability reporting.
Having said that, what bugs me most is that people think the instant messaging format as suitable for everything: activism, jobs, crimes, broadcasting 1970’s prog rock for extraterestrials , whatever lmao. Do you really want to use your phone for all that? Like, just carrying the phone around in the first place nullifies your other precautions, for all advanced threat models beyond privacy of non-critical social messaging.
Persistent/resourceful adversaries can eventually get to you, using a set of penetration and intelligence techniques, which means, if you are involved, the convenience of messaging your partners in crime from the phone in your pocket while waiting for a bus is a convenience you probably can’t afford.
It’s impossible to escape the surveillance of those three letter agencies. We only got a brief glimpse into the other side of the curtain back in 2013, and there is no idea how advanced their surveillance technologies are, so why bother for a normie?
It’s also painstaking if not impossible to wipe all your metadata from the internet, which can later be mined to infer personal data and sold by data brokers. Not to mention that people have jobs and use their credit cards, no way even to hide the most important personal identifying information.
So using Signal, despite being centralized, is not too bad at all. Very few people can totally sacrifice convenience for privacy.
Use Signal or Simplex.
Signal does require a phone number. However, as long as you understand what that means you are fine.
Would recommended SimpleX over Signal if you want the “best”, but for users that are pretty new to this maybe Signal
Conversations for android is an example of a good XMPP client.
Any iOS equivalent?
Monal comes close.
The German technology blog Kuketz has a comprehensive overview and comparison of all major messenger services.
Thanks for sharing. Very useful.
Kind of limited due to there not being an iOS version, but Briar is pretty decent. It was made to be usable in repressive areas by press and other groups, as well as in areas where bad weather has taken out cell and regular wifi. Can be used with phone data, but also offline via ad-hoc wifi and bluetooth. But stuff like Signal and SimpleX are more overall useful to more people (and I think SimpleX also supports offline local immediate area of each other like wifi and bluetooth but I don’t remember atm).
That article in Signal is bogus. It is entirely based on speculation from how funding comes in, and also either ignores, or misunderstands how Signal fundamentally works.
The EFF recommends Signal, and it’s one of the most secure ways to communicate.

You can make your own decisions, but if you just grab any random arguments, you’ll find a reason to doubt everything.
Lemmy has some sort of slander campaign going against Signal. Can’t tell if it’s just misinformed idiots or a paid shill smear campaign being run here (likely the former, Lemmy is too small for companies to give a shit about.) It’s really annoying. Same with Mozilla and Firefox. Not sure Lemmy likes anything?
Give me your phone number so I can chat with you on signal about this.
Signal has usernames (must be enabled) and you can have your phone number hidden from public view & prevent it from being used to search up your acc
That got added recently, but you still need a phone number to sign up. A phone number is tied to your identity, meaning that signal’s database has the names and addresses of everyone who uses it. And since signal is US-based, its subject to US national security letters, meaning its illegal for signal to tell anyone that the US government has requested information about who they’re talking to.
Under the Obama administration, an average of 60 NSLs were issued every single day.
I’m sot trusting anything from signal themselves, just like I wouldn’t trust anything apple, microsoft, google, or any other US-based company with centralized services says about themselves.
It’s not too difficult to establish a Signal account from a burner number from a prepaid sim card. I currently have a Signal account tied to a sim not in my name. Getting a burner with cash is an option. Or, if you’re lucky enough to live near a payphone and can gain access to the number, you can activate a signal with a phone call.
There is no reason to do any of that. No one forced signal to use phone numbers as their primary identifier, and plenty of privacy oriented chat programs don’t require that.
You can make your own decisions, but if you just grab any random arguments, you’ll find a reason to doubt everything.
Agreed. Especially if your source is Dessalines. 🙄
The US-state-department funding is important sure, but you also ignored every other point in that article.
If you really need it to be secure and private, and are communicating mostly with known acquaintances within a reasonable radius, with low bandwidth requirements, LoRA with encryption is the best bet.
It is a higher bar of entry but at least you can be confident your messages won’t be intercepted in any useful form.
Meshtastic can do this, and leverage other nodes as relays.
I have been interested in trying out LoRA and just need to get some devices built. Though I am not as concerned about the super privacy part (thought that is nice). I am thinking that it would be good for emergency situations like shit that has happened with the south-east. Even if the communications would be limited to text, shit is good as long as I can use simple solar panels and battery banks.
There are a few that do a good job of protecting our messages with end-to-end encryption, but no single one fits all use cases beyond that, so we have to prioritize our needs.
Signal is pretty okayish at meta-data protection (at the application level), but has a single point of failure/monitoring, requires linking a phone number to your account, can’t be self-hosted in any useful way, and is (practically speaking) bound to services run by privacy invaders like Google.
Matrix is decentralized, self-hostable, anonymous, and has good multi-device support, but hasn’t yet moved certain meta-data into the encrypted channel.
SimpleX makes it relatively easy to avoid revealing a single user ID to multiple contacts (queue IDs are user IDs despite the misleading marketing) and plans to implement multi-hop routing to protect meta-data better than Signal can (is this implemented yet?), but lacks multi-device support, lacks group calls, drops messages if they’re not retrieved within 3 weeks, and has an unclear future because it depends on venture capital to operate and to continue development.
I use Matrix because it has the features that I and my contacts expect, and can route around system failures, attacks, and government interference. This means it will still operate even if political and financial landscapes change, so I can count on at least some of my social network remaining intact for a long time to come, rather than having to ask everyone to adopt a new messenger again at some point. For my use case, these things are more important than hiding which accounts are talking to each other, so it’s a tradeoff that makes sense for me. (Also, Matrix has acknowledged the meta-data problem and indicated that they want to fix it eventually.)
Some people have different use cases, though. Notably, whistleblowers and journalists whose safety depends on hiding who they’re talking to should prioritize meta-data protection over things like multi-device support and long-term network resilience, and should avoid linking identifying info like a phone number to their account.
Matrix is decentralized, self-hostable, anonymous, and has good multi-device support, but hasn’t yet moved certain meta-data into the encrypted channel.
yet? do they have plans? I’m (relatively) a fan of their platform because of federation, but I thought that it’s not really possible, or at least a very much lot of hard work and even more to change that
I don’t remember the statement in the bug report verbatim, but it indicated that they intend to fix it, which is about what I had previously seen on other issues that they did subsequently fix. I expect it’s mainly a matter of prioritizing a long to-do list.
I can’t think of a reason why it wouldn’t be possible. The protocol is continually evolving, after all, and they already moved message content to an encrypted channel that didn’t originally exist. Moving other events into it seems like a perfectly sensible next step in that direction.
Almost all those can be self-hosted, and built from source, so matrix, xmpp, simplex, are fine. Don’t use anything that’s uses a centralized server in a five eyes country, like signal or threema.
How is Threema in a five eyes country?
I mean, sure, only the clients are open source. Don’t use it for that.
Just out of curiosity: why is nobody recommending Tox?
Wire is the best for security (it literally won’t let you send messages unencrypted), cost (its free), privacy (no phone number required), and usability for the masses (Foss client on all the platforms, messages sync between each client like you’d expect)
I haven’t found anything that checks all those boxes other than Wire (though I do wish we had other options that came close)
XMPP lacks good clients and suffers from fragmentation of protocol standards implementation
- For Android: Conversations is excellent, also on F-Droid if you don’t want to use the Google store.
- For iOS/MacOS: Siskin or iOS/MacOS: Monal.
- For Linux/Windows: Gajim or Linux: Dino.
“Protocol fragmentation” is not a valid complaint about XMPP – it’s like complaining that ActivityPub is fragmented; but that’s not a problem: you use the services (Mastodon, Lemmy, Kbin, etc) built with it which suit your needs, mostly interacting with that sector of the federation (eg, Lemmy+Kbin), but get a little interoperability with other sectors as a bonus (eg, Lemmy+Mastodon).
I fucking love gajim (but I call it Gaijin because it’s funny to me.)
I don’t consider those comments regarding Matrix as problematic. Don’t use someone else’s server if you don’t trust them - including a third party lookup server.
/selfhosting Matrix
The article he linked specifically mentioned that the data is sent to matrix’s servers even when using a self hosted server though
… if you configure to use their lookup server.
So, we have reasons not to use Signal, reasons not to use Matrix
yes, nearly all possible things in the world have been argued by someone somewhere already
From what I’ve seen there’s a lot of very bad security advice out there with even tech journalists and such just straight up repeating stuff they don’t understand
These reasons are serious and valid. That’s why I provided links, so as not to be unsubstantiated.
This whole subject is such a chestnut here. No messaging option is perfect, you will need to compromise. If a perfect option existed you would have heard of it already. And if you haven’t heard of it, then by definition it must be small with few users and even fewer maintainers to keep an eye on its codebase and security, which is risky in itself.
All messengers have their flaws, I’m well aware of that. I was interested in hearing users’ opinions regarding these shortcomings, not in finding the perfect messenger. I may have worded my thoughts incorrectly though, sorry for that.
