Free encrypted messengers similar to WhatsApp for iPhone, Android and desktops exist, and some open source apps don't ask for a phone number.

@Tutanota Signal! Works great, very easy to use and doesn't require PHD to understand it
@Tutanota My favorite Chat app is Threema. Both private and anonymous.
@Tutanota There should be another row, "is it hosted in the USA", since that makes them liable to a FISA warrant and a government mandated backdoor that they can't disclose. Main reason Signal is not an option for me.
@Tutanota Signal. Because:
- It is great
- @Mer__edith is fucking brilliant
@Tutanota Your graph is no longer accurate as Signal now offer an option without revealing your phone number.
@etherealfields @Tutanota But phone number is still required to log in and use it.
@draisinen_dieter , yup already been pointed out, thanks - looking at Threema :)

@etherealfields @Tutanota They still require a phone number to use so no, it's not a viable option.

"The less identifiers a database has, such as your real name, email, and phone number, the better. These are linkable attributes that only the sender and recipient should know, not the server or any intermediaries."

Why not Signal?

@etherealfields @Tutanota But Signal still needs your phone number. You're not anonymous to Signal, or to anyone using an older Signal client from before usernames. And usernames aren't exactly anonymous, either.

@Tutanota

Signal. I don’t have a need for complete anonymity and the folks I need to communicate with securely are already using it.

I keep an eye on the Veilid project and may try to talk my colleagues into it in the future.

@Tutanota
Indeed add Briar to the list

Matrix! 🤩 Decentral, federated and selfhostable. And no dependency on an Android app on a single device to keep the account alive.
@Tutanota I use session, simplex and element
@Tutanota
I have deep reservations about SimpleX. No source code, one very private developer with a Russian name. Sounds like a honey-trap to me.

@Tutanota #XMPP is an egregious omission here. Mature IETF standard, federated, #FreeSoftware clients _and_ servers, end-to-end encryption...

You don't need a phone number or even an email ID to use XMPP, but you can also choose Quicksy for easier phone-number-based onboarding.

I've written a "Quick and Easy Guide to XMPP" here. https://contrapunctus.codeberg.page/the-quick-and-easy-guide-to-xmpp.html

Quicksy

A spin-off of the popular Jabber/XMPP client Conversations with automatic contact discovery. Sign up with your phone number and Quicksy will automatically—based on the phone numbers in your address book—suggest possible contacts to you.

@contrapunctus @Tutanota very good guide 👌 I would just mention #fdroid as a mean to get #quicksy . I will probably use your guide instead of joinjabber which is very confusing for new comers 🤔
@Tutanota Signal: because it is easier to get other people to use it than something like Session or matrix/element. Also: no headache setting it up for and supporting relatives. It works as they expect without hassle. Signal may not be perfect, but installing anything else with “the best” privacy that nobody I know uses/can’t convince to use is still worse than simply not using anything. But I can’t live like a hermit without communicating.

@Tutanota I hate all of them. I use Telegram because it's what people use and at least it's better than Whatsapp. Me and my partner tried Signal but it lacks many features. I have no idea any of the others in the picture.

Choosing a chat app works only when no friends...

Chat apps should be forced at once to share the same protocol or whatever, so that people on Signal, for example, can talk to people on Telegram, for simple text at the very least. That would finally make people choose what they truly want to use, and not use because of their friends. We need EU to force that at once.

Signal all the way
