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.

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.
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.

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.
Let me message you without having an Android or iOS primary device then. Can’t do it.

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.
Do you make the same criticism of TOR?
That rabbit hole goes very deep, but I’m not knowledgeable enough to speak on it. It could very well be a crypto AG style honey-pot, or already cracked tech, that we might not know about for years to come.
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.

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.
What level of attacker do you realistically need protection from?
Removed by mod
Depends a lot on who you’re talking to, and your, and their threat models. For many, signal provides pretty good protection, which brings us to a salient point, anything that actually provides good security will attract plenty of negativity, often from state level actors who feel (are) threatened. If you’re playing at that level, adam_y is right, dead drops and one time pads. Presuming lesser threat, signal beats telegram and FB etc. Email is plaintext unless proton to proton, encrypted email is fine (look at PGP) and indeed if you encrypt at home before sending it’s pretty much a dead drop anyway, as long as the other party has a key, and I’m wandering off the beaten path.
Seems you want a secure messenger that works and are scared by random crap because you don’t have the relevant knowledge to decide (spoiler, very few do, and it’s insider knowledge, the world is imperfect), fair enough, but don’t let perfect be the enemy of good. As long as you’re willing to give up your phone number, Signal is well regarded (exchange privacy for security, you decide). But yeah, no perfects, world imperfect, trust hard, deal ;)
Dead drops and one time pads.
Set up a numbers station if you can afford it.
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.)
Do those ios clients support push notifications?
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.
There’s a 90% chance the other end of your conversation will be with someone on Matrix dot org or a server they host for a organization. Like email, your other end is likely still using Google or Microsoft so the metadata & anything else unencrypted is going to be synced back to the centralized server.
The German technology blog Kuketz has a comprehensive overview and comparison of all major messenger services.
Thanks for sharing. Very useful.
For me SimpleX does everything I need. Unified push would be nice, and would address battery usage. I don’t need or want message sync, so that’s not an issue.
They all have tradeoffs, so it’s just a matter of your priorities. For instance I’m OK with the higher battery drain because it’s not using Google.
Simplex.chat
No identifiers, pfp, FOSS, can route through tor.
Or host your own matrix or xmpp server.
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.
Not to mention that people have jobs and use their credit cards, no way even to hide the most important personal identifying information.
Exactly, this is a lost cause. If you participate in society your essential data are simply out there. For most people the task is to minimize their footprint. If we are talking about evading mass surveillance, then we should take for granted that the person will be to one or another degree marginalized, or lead a fringe lifestyle.
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.
Motal is participating in GSoC this year to get some new features too.
But this is a wider issue that developing free software for Apple products is way too expensive (time & money) to be feasible while also going against the general free software ethos. It should be no surprise the walled garden of a proprietary OS that charges you to publish to their store has a severe lack of free or otherwise ethical software (which is important for security for something as important as a messaging app full of private data).
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
Briar is really interesting but it doesn’t work as well for a casual messager. It is a bit complex to setup and very hard to understand unless you have strong knowledge on the subject. I think it is very powerful but breaks the standard convention most messaging applications follow.
