Finally bits been ages.
A number is still needed to register I believe.
Requiring a number is a good way to limit bots.
A PoW could limit bots too. Require say 30 seconds of work before your registration submits. For regular users that isnt to bad. For bots its a PITA to get tons of accounts
Edit: tor uses PoW as DDOS protection and its helped massively
PoW…Prisoner of war?
That will also keep away bots.
You can only sign up if you’ve taken at least one Prisoner of War. Bots can’t take prisoners of war for obvious reasons.
Kinda like how Aztec boys came into age in their society.
Proof of work. Example, bitcoin
How does this prove anything if using an emulator to bulk register bot accounts?
For each account you register, you have to do 30 seconds worth of work. So to register one account, you do 30 seconds worth of work. To register 100 accounts, you do 100*30 or 3000 seconds (50 minutes) worth of work. Registering tens of thousands of accounts then becomes unfeasible.
And how can a VM or emulator NOT do this?
It was the original purpose of the bitcoin algorithm to limit spam.
If you have to do a lot of maths that takes your computer (for example) 30 seconds, that means it costs 30 seconds of compute to create an account. Nothing to an average user, for a spammer that wants thousands of accounts it gets expensive.
Several captcha[0] libraries already use this and it’s great for accessibility (normal captchas are terrible for it)
[0] I know, it’s not technically a captcha.
Pow does not limit spam in bitcoin. Fees do. Pow is used as a decentralized election mecanism to distribute the block production.
Accessibility is very important to me as a blind user, and this helps tremendously.
Oh, neat. I was unfamiliar with PoW. Thanks!
I know what it is. It is not a barrier to entry though.
Kinda stupid for privacy to hand over your phone number… Very counter intuitive
A number is still needed to register I believe.
Indeed, which makes their headline a bit misleading. Having to give Signal your phone number is not keeping it private.
Wrong, it still keeps it private but not anonymous. It’s not the same concept and for most thread models knowing that you use Signal is not really an issue, especially since with this feature no one can check if you have one if you don’t give them your username unless they have access to Signal servers in which case they still have nothing except the knowledge that you have an account.
They do a lot of work to keep your phone number private, or at least any data that is tied to it. This username upgrade is solely for someone to communicate over Signal without needing to hand over your phone number.
For example, you can now be in group chats with internet strangers by just giving them your username.
On top of that, once MLS is adopted, you can communicate with other messengers as well.
I thought peoples big problem with it was not wanting to give others their number to use signal? Like I meet Joe Blog online and don’t want to give him my real number to chat.
Less people worried that signal had their number?
Seems the second group is a vocal minority. This feature helps the first group, but doesn’t help the second group.
According to Signal, the first group is the larger group and this helps the most users of Signal.
Could it be better? Sure. This is still a good step in terms of privacy, even though it doesn’t really improve anonymity.
Its important to not let perfect be the enemy of good.
Personally, I care about the phone number requirement not because I don’t want to reveal it to Signal servers, but because it limits access to Signal for people in countries that block their SMS service - registration messages just don’t arrive
It’s specific to signal? Like they want to block people registering or what’s up with that SMS block?
Not specific to Signal. I believe he was referring to places where Twilio doesn’t serve, for example because of sanctions.
Putting a SIM card in a phone exposes it to enormous surface area of attack. People have been asking to register with anonymous emails instead of a phone number, like Wire has had for years
Do you need the SIM card inside the phone after registration?
Does it matter? At that point your phone is owned by Pegasus et all with zero click vulns
I thought peoples big problem with it was not wanting to give others their number to use signal?
The issue is that giving your phone number to Signal Messenger LLC is giving it to others, and therefore not keeping it private in the usual sense of the word.
Some people may be unconcerned about a corporation knowing their number vs. their contacts knowing their number, but that doesn’t diminish the misleading aspect of this headline.
Just yesterday, somebody commented that Signal might be adding the feature in a few weeks. I was incredulous, assuming it would be months.
Nope. As soon as I saw this, I went looking for an app update, installed it, and made a username.
To be fair, it has already been years
It has kinda been a meme that it’s coming for years
Hi, “somebody” here o/
I’m still just so furious at Signal management for removing compatibility with other text apps. I used to be constantly growing my Signal network, now it’s a slowly shrinking rump that I never add anyone to.
Wasn’t that compatibility based on SMS which is inherently insecure?
On Android, it moved SMS messages from the shared SMS store upon receipt and to Signal’s own database, which was more secure.
Right, the idea was that you could use Signal as your SMS app, and so whenever there was someone else doing the same you’d automatically upgrade to Signal. Whereas now I never have those auto-upgrades, any new contact I am just stuck on SMS with.
In my opinion, relying on upgrading users automagically to an encrypted and secure protocol isn’t good practice. If someone wants to use an encrypted chat, they should do so consciously. It will only cause confusion otherwise.
Do people still use SMS these days though anyway?
I would have thought iMessage, RCS and separate chat apps like Whatsapp, Signal and WeChat would have largely replaced SMS by now.
Yes
I think its great. Its for people who simply don’t want to share their phone number with other people which is a huge privacy concern, as you can find out a lot about a person by looking up info connected to their phone number.
About time!! Been waiting for this for so long. This will definitely make the usability of Signal better and it’ll also be more accessible to people who wanted a Telegram like way to talk to other folks. Requiring a number to still register isn’t a bad thing in my eyes though sometimes it can be frustrating so I hope that there’s an option to create an account without a number. Maybe the account will have finite time before it’s auto-deleted if you don’t input a number some time later to ensure that this option isn’t abused to all hell by bots and malicious actors alike.
its a sensible choice because many potential implementers hae been dissuaded by the anxiety attached to risks of giving out phone number. (harrassment, stalker, spammer, scammer) . the telephone system has paralyzed itself in fear. yet we all keep buying their shit.
Maybe the account will have finite time before it’s auto-deleted if you don’t input a number some time later to ensure that this option isn’t abused to all hell by bots and malicious actors alike
we’re already banning bots, thus effectively making them time-limited. Yet we still have bots and spam on there. This sadly won’t work.
Great, I’ll get more spam
Did you read the article? I don’t think temporary usernames will increase spam.
I just got a unknown sender sending me unsolicited junk and that’s never happened before
Telegram have this in a long time, and I never got any spam messages.
Try to read the article instead.
Don’t bother with this person. All I’ve seen them do is read the post’s title and produce an (often inappropriate) reaction to said title. Peak Redditor.
Updated on iOS via US App Store - feature not available just yet. Looking forward to it in a few days perhaps!
found this in the article
Right now, these options are in beta, and will be rolling out to everyone in the coming weeks.
Same for me
I mean it’s nice but I do not know a single pirson who uses signal
Hi friend!
Now you do.
Great news. Thank you Signal
Still register with a phone number is a red flag. I prefer SimpleX.
Great feature, but if I’m reading it correctly, you won’t be able to chat with someone anonymously (because your profile will still be shared). Are there good apps for that?
SimpleX
Threema?
SimpleX was the best for my purposes when I looked, but Briar is a compelling option as well.
The case can also be made for element, but it lacks forward secrecy and honestly the app kinda sucks.
jami
It was nice to use it in nightly. It’s good it came to stable.

This is important context. Signal needs to make phone numbers optional…
Nah.
Yeah.
omg so cool right? they finally invented usernames. IRC is jealous.
