Do you prefer Threema, Signal or Matrix? Why?

It's an issue.
You can't create an account on desktop. You can't create multiple accounts. You can't create an account at all if you don't have a phone number. You can't create an account if your phone number's previous owner created an account. Signal can be subpoenaed for your phone number.
Is it possible to use a number different to the one on the device you use? Seems like a simple workaround to use a throwaway SIM to set up, and then use it with that number moving forwards.

OK, and how is that different from the other chats?
You do know that at least Signal and Matrix use pretty much the same crypto, right?
And Matrix can be self-hosted, so I don't need to worry about what they can see anyway.
On this point alone Matrix appears more secure than Signal...And Threema is Switzerland-based, so by default it's more trustful than a USA-based company.
The metadata is really important especially if you or anyone you talk to ends up being targeted. 95% of intelligence work is mapping out adversaries' communications networks..if you have that, you don't need to decrypt the contents because you already know who is talking to who. The federation of metadata alone is reason to avoid matrix for anything important.

So, I have a Threema license, but from what I've seen its encryption isn't post-quantum. Signal's encryption seems the strongest. I host my own matrix server.
Also, I kind of don't care where the servers are or which provider it is. Everything is encrypted anyway.
Post-quantum isn't really a big problem because it will be a very long time before there are viable quantum computers (maybe never). You should focus on the very real risks of security breaks from normal negligence and design errors.
Threema seems pretty unpopular, so the risk is highest. Signal and Matrix are both popular and have a lot of scrutiny on their cryptography.
All 3 have open source clients, but Signal contains some binary blobs. Only Matrix has an open source server, though end-to-end encryption enforced by the client alleviates most of the concern of proprietary servers. All 3 support end-to-end encryption.

Threema has been audited multiple times.

That sounds like an awful lot of work to workaround a problem that shouldn't have existed in the first place.

Self-hosted Matrix.
It still needs polish, but it's on a good path. Meanwhile others are centralized by a single authority with an easy target painted on them for government coercion along with multiple other attack surfaces, and even information easily traced to PII.
By contrast, a drop in the ocean is far more likely to not be targetted from the outset, making pretty much any matrix server (potentially with the exception of the matrix.org one, but it's ok to treat it as a demo anyway) a really good choice in that sense. -
All the fucking people that actually know cryptography and are experts in their areas.
It's good to be inquisitive but at some point if a person is not qualified to understand either you gotta belief some authorative figure or pay someone you trust to go review the code if you still don't trust it.
Multiple experts have said for years that it's solid. There's audits out there. It's used in the most extreme places where people need to survive and commucate securely and governments keep screaming they need backdoors because they can't fo anything about it.
At some point the whole questioning it has to stop.
Continuing to eat garbage opinions from the internet and growing conspiracy theories eventually has a limit.
Sure, buddy.
Maybe you should read the comments you're replying to first.
If you can't do that much then maybe you just shouldn't comment at all.I'll simplify it for you:
- Did I suggest Signal is not secure? No.
- Did the OP make a claim Signal is somehow the most secure chat on the planet based on non existing sources pulled out of his ass? Yes.
Discussion quality on Lemmy starts looking like Reddit now.
Almost feels like home... -

Thank you for being one person in this thread that actually read and understood my comment.
A bunch of comments repeating "Signal is the most secure because I said so" was not helpful.

I liked the Matrix because of all the kung fu karate fights, though I got to say the second one was the best, even though the third one had a Dragon Ball Z fight at the end

I just saw your reply to me and was about to say the same thing, but they worded it perfectly. And I did mention metadata as a key point in my original post.

Yes: mine uses a Google Voice number.
