signal requires a phone number to sign up. a phone number could be used to trace your signal account back to you. so why do people, especially privacy enthusiasts and experts (like edward snowden), still use it and endorse it when it lacks anonymity in that sense? i get that people could use a voip number or something to sign up, but still.

    Privacy and anonymity have some overlap, but are ultimately two different things. Signal focuses on privacy.

      I don’t undestand this comment, could you please elaborate?

      The way I way I see it, privacy without anonymity only works if you can trust a service provider. Since there are no trustworthy providers, especially since legislation can cancel any assurances anyone could give you, anonymity becomes the only way to ensure privacy, making it virtually synonymous.

      • Privacy means that you can talk/act safely in your own closed-off space while no-one knows what you do. The opposite of private is public.
        Anonymity means that you can safely talk/act in public space while no-one knows who does it. The opposite of anonymous is … identified.

        If you want your talk be private while doing it in public or via an untrusted service, you can use obfuscation/encryption of the content/payload data of your talk (still anyone could receive it and know it’s from you and if they have the key they can decipher it).

        If you want to be anonymous in public space, you have to obfuscate the metadata of your talk (so that no-one knows who said it but anyone can still receive it).

        *And here is a bit of an overlap depending on where we want to draw the boundary of our privacy realm. In some cases, the knowledge about metadata like location and time of a message can be breach privacy while in other cases this is irrelevant.

        You could also do both, meaning you’d have an anonymous appearance in a public/untrusted space, having a conversation with only those people who have the key to your messages. That’s a stunt which is not easily accomplished, as obviously you’ll need a way to let others know how to reach you, and exchange keys (in other words, you’ll have to first make an appointment in private and in a trusted space).

    This is a well known issue for a lot of people and signal has been promising to fix this for years. Using a phone # for verification reduces spam and bot accounts, but like you said it drastically reduces anonymity.

    That said, anonymity != privacy. You could anonymously place a note on a car telling the owner to learn to park, but it’s not private since anyone walking by could read it. Likewise you can send an encrypted signal message to another user who knows who you are, so it’s private, but not anonymous.

    Signal is great for private communication with people you already know and trust. I was in a situation where I was organizing with new friends, and we had a big group chat on Signal. I cloned Signal to a work profile, and registered it with a cheap VOIP number, so that I could keep my real phone number separate from my political organizing activities.

    Remember, privacy and anonymity are not the same thing. Signal is an app for private communications, not anonymous communications.

    You can have privacy without anonymity, and you can have anonymity without privacy, and either/both of those can be secure or insecure.

    They’ve repeatedly stated that they’re working on removing the need to share your phone number with your contacts, but that’s taking some time, because they want to implement it in a way that does not involve storing your entire social graph on their servers.

    You’ll still have to sign up with your phone number, but the only thing that can be traced back is that your phone number is registered on Signal - and only by subpoenaing Signal, I believe.

      Btw, the main thing to realise, is that Signal is trying to tread the delicate balance of being accessible and private. If you have the perfect private messenger but nobody uses it, that doesn’t help democracy one bit. So starting out with an easier-to-implement mechanism that also helps adoption (because people can get notified when people they already have in their contact list join), that still protects against indiscriminate mass surveillance, makes sense to me, even if it means your contacts can still know who you are.

    With focus on anonymity matrix is better than signal, with focus on privacy signal is probably better, just because you are forced to use encryption.

        That’s like saying there’s no point in having bathroom doors because everyone can see you going in.

            Then you need both anonymity and privacy. Sometimes you do need both but they’re not the same concept.

            Privacy without anonymity is you using the bathroom with everyone seeing you walking in. They know you used the bathroom but have no idea what you did inside.

            Anonymity without privacy is like you pissing on the street with a ski mask on. Everyone saw what you did but no one knows who you are.

            Having both is walking into the bathroom with a ski mask on. No one knows who you are nor what you did inside.
