Signal has finally introduced usernames so you can use it without giving out your phone number. This is the number one feature I have seen prevent people from using Signal for many years and I’m happy it’s here!

@evacide That's great news! It might make me reconsider using Signal, indeed. Though, I'd like for the phone number to be optional altogether.

@SamantazFox @evacide So you still need to provide a (non-VOIP, non-landline likely) phone number to use it?

dragonfrog, hungry waffle

@DeltaWye @SamantazFox @evacide

You do still need a phone number to register for Signal, yes.

@evacide Very happy with this change. The next big thing form me would be a desktop app fully equivalent to the mobile app, especially able to seed a new mobile when the old device is lost or defective.

@evacide I thought it would have been requiring you give Signal your phone number in the first place (which you still have to do).

@evacide However, afaik you still have to give them your phone number to _sign up_ tho, and it's very likely one of the few data points they save, so you do remain identifiable to anyone who can access their user data (or lawfully make them hand it out).

@incoherentmumblings @evacide Your phone number is your new social security number, basically. One common data point that can seamlessly connect the dots across thousands of different platforms.

@incoherentmumblings that's correct. However, the only data they have is that you have a signal account and the last time (not place and not how often) you connected to the signal network. We've seen that already play out through legal subpoenas. I understand that it may not fit everyone's risk profile but it's fine by mine and I'd imagine the vast majority of people. But it's good to know that detail and make an informed choice.

From what I can read, there is no mention of being able to register a new account without a phone number. It's all about not giving your phone number to anyone else (Signal of course already has it, and automatically ties it to your username).

If new accounts can be created without requiring a phone number, this is actual privacy improvement. If not, it's PR bullshit.

Has anyone tested this?

@andymouse @evacide "you will still need a phone number to sign up for Signal"
This is just for contacts

Trevor Goodchild

@andymouse @evacide what do you use that provides what you are describing that is as good as signal E2EE?

Falcon Darkstar

@andymouse respectfully, it makes a huge difference. I am a lot less concerned about Signal having my phone number than I am about every random I happen to be in a group chat with being automatically given my phone number.

@evacide With which update? The current one on iOS does not yet offer this option. Or is the function only in the beta phase????

nusse

@evacide is it really true? Why would it depend on the version other users are running? "Once these features roll out, your phone number will no longer be visible in Signal to anyone running the latest version of Signal "

raspberryswirl

@evacide if you have the number signal knows, still bad.

Interpipes 💙

@evacide I’m concerned about this:
“your phone number will no longer be visible in Signal to anyone running the latest version of Signal”

This suggests that if bad actor keeps old signal on their phone, they will still see your number?

(Also, it implies that hiding the number is a receiving-client-side decision?)

momo

@interpipes @evacide
Did you read the article?

Let me help you with a citation:

"Each version of the Signal app expires after about 90 days, after which people on the older version will need to update to the latest version of Signal. This means that in about 90 days, your phone number privacy settings will be honored by everyone using an official Signal app"

Interpipes 💙

@momo @evacide ah, good to see. I did read the article and I went back and still couldn’t see it, but it turns out that particular paragraph is hidden under an ellipsis I didn’t open, which is a strange thing to do with a critical explanation of how users would be protected.

Interpipes 💙

@momo @evacide but it nevertheless still suggests that the network still sends the number in the message and the client is simply coded not to show it

Interpipes 💙

@momo @evacide also, on reflection, how much work is “by everyone using an *official signal app*” doing in this sentence - are there unofficial signal clients (that will be able to choose to display the number)?

momo

@interpipes @evacide I do not work for signal and have no access to the source code of the server implementation. I think these are questions you could ask the people working at signal:

- support.signal.org/hc/en-us/re

Interpipes 💙

@momo sure. They're also questions I'd direct at any trusted party suggesting that this is safe to rely on because my reading of the totality of what's been provided by signal - now with the benefit of the paragraph you highlighted - is that it *isn't* safe to rely on given the existence of 3rd party signal clients, so I was wondering if @evacide or anyone else who saw this thread perhaps *did* know better or saw something I've missed.

Interpipes 💙

@be @evacide interesting, but if it is not accessible to the client when the sender hides their number I wonder why the recipient's app version matters, then, and why the wording of the post is so very specific about "official apps"

@evacide Without giving out your phone number TO YOUR CONTACTS. You still have to give it (at least a number you control) to Signal.

Matt Cengia

@phocks unless you're in a position to join the beta. :)

Josh S. Pumpkins 🎃

@mattcen I joined the beta yesterday I thought. Maybe I just need to wait for the update :)

Cliff Barbier

@evacide
Ugh! Finally!

I give a GVoice number out to professional contacts, but can't use that with Signal. Now, I can just give them a username!

I am Jack's Lost 404

@evacide

Does this make it independent of the system contacts list now?

Sibachian

@evacide the number 2 reason being it's dependency on electron/chrome.

am i the only one beyond tired of lazy and slow electron apps hogging up my system resources?

Clayton

@evacide I don't know about it being a number one reason... I don't use Signal because it's yet another walled garden. For some reason people still think those turn out well long term for users (they don't.)
