Today, most messaging apps have true end-to-end-encryption (Telegram’s must be activated per contact for Secret Chat), but what really differs now is how many can tie your communications back to you through metadata. Obviously those which require a phone number or an e-mail address, do have your activity tied to you potentially.
WhatsApp, Signal, Telegram and similar do require this for registration. Partly it is for authentication, finding friends, and also for resetting access if access is lost. What data you can see after a reset, gives an indication of what the provider has access to. For Signal, you won’t be able to read any of your older messages. Signal indicates in this linked article, though, that they only keep the very minimum of information (tested by a legal subpoena). Telegram has more access as that is how all your chats get restored, but they have been banned in various countries because they don’t hand over the information. WhatsApp, of course, we all know about their passing of detailed metadata upstream to Facebook (it’s in their terms and conditions). I’ve done a post before about the risks and the monetary rewards around harvesting metadata. Just by registering on WhatsApp, you have also shared all your friends’ phone numbers to Facebook, along with how often and how long you contact them, where you are when you contact them, etc.
We’ve also seen lots of secure messengers emerging that require no phone number and also no e-mail address, eg. Briar, XMPP, Jami, Threema, SimpleX, Nostr, and many more. Many mainstream users don’t adopt them because the common problem is, you can’t find your own friends easily (who do you chat with then?).
So this is one of the reasons why Signal has been pretty popular as a secure messenger. It requires a phone number, but retains virtually no information about you to sell or leak, and you can very easily find all your friends using it. So no, it is not THE most secure messenger, but it is certainly the most secure of those requiring a phone number or e-mail address for registration.
But the main takeaway is, unlike with an SMS app where only one app may be the active SMS app, your phone can have 10 or more instant messengers installed, so there is no reason not to also have Signal installed. It helps your friends, who are more privacy conscious, to stay in contact with you via Signal. Whether a message notification pops up via WhatsApp or Telegram, It’s still going to pop up, unless you have a friend that insists on contacting you through two apps at the same time. Most modern messenger apps use push notifications, so they are not constantly polling, which uses data and battery all the time.
Go ahead, try more than one messenger, and you may be amazed that there are often better and more interesting features to try. Many of your friends will thank you.

But I don’t want to have to manage 10 different communication apps, and I don’t want to be in a walled garden, and I don’t want to wrestle with my contacts about which app to use. I want federation.
F*ck off Signal. I choose Matrix instead.
Well I use Element for Matrix as well… but why not 10? You only really manage them once when set-up. After that, you just respond to whoever messages you, or you compose a message of whichever one. They no longer chew battery or data in the background. I have 11 installed and there is really no “extra” effort.
Honest question because I have no experience with this, but what about if you want to send a message; wouldn’t you have to keep track of which people are on which app, and if you forget you have to go through each one to find them? That could get quite burdensome with many contacts.
Inside the app it just shows who is on Signal now, when you start a new chat. It no longer sends SMS to anyone.
You will get it, courtesy of the EU. Look up the Digital Markets Act. Big names like Facebook Messenger, Apple iMessage and such will be forced to federate.
And that’s just the start, like 20% of the full scope of the already accepted bill. It will be a bigger shakeup than the GDPR when it gets implemented.
Yes but the EU also wants to ban encryption.
Let’s see what shape the laws take after they’re written, rather than running purely on what we hope they will be.
Signal is easier to get into and with the upcoming implementation of usernames and hiding phone numbers I think I will convert all my friends on there. Aside from that, you could create your own Signal server if you want and unlike Matrix, it doesn’t leak any metadata.
I like the idea of Signal, and would probably love to use it, but everybody I know (and everybody is still don’t know!) is using WhatsApp, and there’s no way they all are going to migrate.
Be the change you want to see!
If you want to advocate in the easiest way possible, I’d advise you install it even if you don’t use it. That way if others join it, they’ll find people vs seeing nobody is on it and then uninstalling it immediately. I went this route and went from not really using it to now being almost 99% of my communications. Everyone at work has started using it as its easier between iOS/Android especially if you have people in your groups that refuse to install meta/facebook products.
@Thy_Moose @GadgeteerZA using Signal
I describe signal as a journalism and cybersecurity nerd app. Because everyone who’s serious about either of those two things uses it. The other apps don’t come close.
Still a bit peeved at them removing SMS functionality from the android app. Now I need 2 apps. If it means they plan to move away from the phone number requirement, then I’ll look forward to that.
I’m also still a but sketched out by the while MobileCoin thing from a while back. Not sure I trust the direction they’re taking, but i’ve tried all the alternatives and found them lacking in one way or another.
I used signal as my main messaging app up until they removed sms from it. Before that point it didn’t matter if most of my friends didn’t use it, I could still communicate with everyone I wanted to regardless of their app. I would even slowly see people join over time, it was really promising.
Then they went and removed sms and now I rarely use it. I keep it as a backup if I ever need to send something sensitive, but that’s pretty rare these days.
I disagree with this “So no, it is not THE most secure messenger, but it is certainly the most secure of those requiring a phone number or e-mail address for registration”. I believe it is probably the most secure messenger. It is not anonymous like Session but it is the messenger that does not know anything about you. There are court cases requesting Signal to give information up and all they are able to give is the last time the person connected to the servers.
I say that purely because there is the link still to the phone number. Law enforcement, or anyone posing as then, have a phone number and can at least identify your Signal account and login times. I agree they can’t read the messages and there is not a lot of metadata.
Messengers like XMPP, SimpleX, Briar, etc require zero personal info to register, and still have full E2EE. There is NO link at all to your identity apart from maybe your IP address if you don’t that have a VPN. But take Nostr - zero information asked for registration and some clients have Tor enabled.
So I really can’t say Signal is yet the most secure and private, until they remove that link. But then discoverability of all one’s friends is also removed, and you have to connect separately to each one. I agree though that they are good enough to pass the bar, but I’m just saying they are not at the top of my list.
Folks just commenting here letting you know that a Signal community is now open on kbin: https://kbin.social/m/Signal
Seems I can’t “see” that community federating through to Beehaw. But I see there is one already on Lemmy.ml at !signal@lemmy.ml which can be seen.
The scummy thing about WhatsApp is that in the terms you agree that you have permission to share your contacts’ information. They almost certainly take the most recent agreement, so if you as an individual object directly to WhatsApp this will be superseded every time someone who has your number agrees to the terms.
I refuse to give a phone number over to use Signal. I use Session; Matrix; XMPP; and Jami all before I would touch Signal.
