Privacy has become a very important issue in modern society, with companies and governments constantly abusing their power, more and more people are waking up to the importance of digital privacy.
In this community everyone is welcome to post links and discuss topics related to privacy.

How I Got a Truly Anonymous XMPP Account:
Sorry, it's a cheap joke, but it still baffles me that Signal requires a phone number, so I felt I had to post it :)
Of course, this is not XMPP-specific either, just my protocol of choice, there are many other open alternatives that also offer such functionality.
And - gasp! - you can do it from your computer directly! No Android emulators, no inconvenient command-line client!
and then you can anonymously chat with yourself because no one else will bother installing that favorite app of yours!
I've been trying to get people off WhatsApp for who knows how many years now. With Signal, i have a chance of convincing people. When you start talking about matrix or session or SimpleX or ???, people stay on WhatsApp
Different strokes for different folks! I've been fortunate enough that many of my family and friends have been happy enough to follow me.
But I don't disagree with you, Signal has a much more recognisable brand and better user experience. These are things that we need to improve if we're going to get anywhere near the level of adoption Signal has.
tl;dr the sms verification falls back to voice and they just used a payphone.
I guess if you count the airport full of cameras they went to to do this as "anonymous", then sure :)
Also this article from 2017 suggests not using this method:
It’s important to maintain control of this phone number. For example, you could use a disposable SMS service to register with Signal — there are many such services if you search for them — but those phone numbers can be used by anyone. Similarly, you should avoid using a public payphone’s number, or a SIM card on which you do not intend to renew service. If someone else can receive SMS messages or phone calls to this phone number, they can take your Signal account away from you.
That risk is not just theoretical. I made a test account (on another service; not Signal) using a free anonymous SMS number. A few months later, the account had been hijacked.
Of course, if it's a disposable account, then having it hijacked after you're done with it might be a good thing.
Signal has account pins now so I don't think the attack vector is as large as it used to be
”It’s important to maintain control of this phone number."
I strongly feel that this is false.
Care to elaborate?
Privacy ≠ Anonymity
Signal = Privacy
Signal ≠ Anonymity
Signal was made for privacy, not Anonymity.
If you need anonymity, don't use signal. It was never designed for this. There are tools specially made for anonymity. Look at simplex.
If I asked 10 people to give me their home address, they're not going to care whether someone defines that as privacy or anonymity. But signal's reliance on phone number's (which are easily linked to your identity and home address in most countries) as the primary identifier means giving away just that.
Why do people feel the need to split hairs with these terms?
I think anonymity is heavily coupled with privacy, if someone knows my account is linked to my phone number, that's a very strong form of fingerprinting. Even if E2E encryption is perfect, it takes one bad actor on the the reciever end of my message to both identify who I am through my phone number and leak my message. If just my message is leaked and there's no fingerprint leading to me, I am still safe. Real example: It took Proton leaking the IP address of a climate activist to the state to get them arrested, not a hole in their E2E mail encryption. A phone number is potentially an even stronger identifier.
Wouldn't just using a temporary phone number service work? From what I remember, you just need to recieve a text message and put it into Signal during registration. From skimming through the post, there's no mention of this option.
What about buying the cheapest SIM card in a convenience store and activate the service with it using a dumb phone?
That might work in most places, but there are countries that only sell pre-paid cards with ID registration.
Protip: in those countries, go to the tourist hot spots and walk into a SIM selling shop. Use a thick foreign accent.
There's always an industry for anon SIM cards for tourists.
That won't work in Australia. You can buy the SIM anywhere of course, you just can't activate it. You'll need proof of ID on line to do that.. There are only three operators (the rest are resellers). I am sure there are ways around it but not the one you suggest.
When I was last in NZ you didn't need ID must buy a SIM and good to go, not sjre thats still the case though?
The way you work around it is the shop keeper probably uses their own ID. There's always a market for tourists
What about a virtual phone number?
Not all of them work, and most require some details to create.
Usually those numbers fall back into the provider's pool after a time of not regular usage and get sold again, at least here in Europe.
The twist they've introduced in this article is they're using the registration lock feature, which means you have a signal pin enabled, so as long as the account doesn't go idle for 7 days even somebody who gets the phone number can't use signal.
7 days?!? Jesus can we get at least a few years?? Thats worse than WhatsApp's 2 weeks.
The fundamental problem is the signal foundation sees the phone number as the identity. If you don't have control of the phone number, you don't really have control of the identity.
The good news is, they let you change your phone number and maintain your contacts. But if the phone number the account is currently registered to get assigned to somebody else and you don't change it, then you're playing the 7-day roulette
