Why do people use signal? It has one centralized server and phone number registration. There are many better alternatives.

[–] Logical@lemmy.world 10 points 8 hours ago (2 children)

Which ones are you thinking of? Out of the options I am aware of, Signal seems to be the most secure, most reliable, and most privacy respecting messaging app in this category.

I use deltachat/arcanechat. It uses the mailchat protocol. There's also tox, simplex, matrix, xmpp(conversations) these can do e2e, you can self host it or use a public server, everything distributed through app stores can be compromised. Every app were you rely on a central server can be shutdown. You also don't know how the server software works of for example "signal", what data they collect. Although messages are encrypted you can still log metadata like when where iplocation, with who?

The problem i guess with thr alternatives is bad service in terms of audio and video chat. The benefit of ms teams for example is their huge cdn. it just works nearly all over the world. Whatsapp/discord is used by so many that it's difficult to stay in contact otherwise.

I've talked to a deltachat dev about this, and the signal protocol is simply technically superior to autocrypt (used by deltachat, etc.). It gives you many more guarantees about things like forward secrecy. There is standardization work to bring these benefits to autocrypt, but it will probably be a while. Signal also has the benefit of having a familiar setup for non-techy people, so it is easier to get people to use in my experience.

Interesting. Ease of use is one thing but requiring a phone number or email to setup an account is in my opinion annoying.

Used to recommend XMPP (lol) but even with whatever encryption the servers still know and control too much. Like who you are chatting with (entire contact book) and when, plus attachments most of the time. And there was also the jabber ru incident... Don't feel like pulling up the article rn but basically it got MITMed by one of the ISPs (counting the hosting provider as ISP), with a new valid TLS certificate and all.

Tox supermacy! What looser needs a backlog, pffff.

It used to be an SMS client too, to help get people on board. Now they expect you to either memorize which people use which protocols, or just use SMS.

[–] Crumpled6273@lemmy.ca 1 points 8 hours ago (1 children)

Don't use SMS. As it is unencrypted, the ISP have complete access over it.

It's not that difficult to remember which people use which messaging apps. I use Signal, Line, Whatsapp, Matrix, Telegram, heck even Instagram DMs with different people. I try to push people to Signal whenever I can though.

[–] explodicle@sh.itjust.works 1 points 9 hours ago (1 children)

Yes it absolutely is! I just use Signal and SMS, and the Signal users seem to be dwindling.
