I very much agree that enabling Protonmail XMPP services should be a top priority for all the reasons mentioned by the Op...
Any developments on this project? I tried to sign in and kept being redirected back to the the main page. :(

Use Signal or Wire
No need for another secure messaging app

I personally use Threema for secure IM, but I think a ProtonChat feature integrated into the web interface would make sense. It would be very handy to be able to chat with your proton contacts without having to write emails.

I use signal and love it, the only improvements I would have would be similar for messenging functionality for Protonmail:

- Cross platform support rather than having it tied to a phone number.
- Turning off emoji (damn, those things annoy me)

Full secure .less buttons .Start --stop .

When you start build ProtonChat.

Threema is the finest in Secure & Private Messaging. It does not require a phone number for identification. It uses a randomly generated ID to be given to other contacts. Wire looks good too, but does not yet have the feature set that Threema offers.

Protonmail does not need to reinvent a great product Threema has already created. Signal is also great if you are comfortable sharing your phone number.

One more option, for Android at least (and open source, available from f-droid), is Silence. I have been using it happily for months, and have convinced contacts to switch. :-D

agreed!

"Telegram' might be an option too, they take privacy and security seriously

@Happy,

Just use Signal for gawdsake! I don't trust Protonmail that much; they can't even fix up their existing bugs in a timely manner.

The reason I want protonchat, is because i trust PM enough that i desire a suite of secure proton-services. And that includes a secure chat/messaging-service.

This is not necessary. There are already great messaging apps out there, with no connections "to the likes of Google and Facebook", which are also free and excel in terms of privacy features.

I know, i know... There are others posts about the same subject. A lot of people talk about "ProtonChat", but the biggest problem here is that there are a lot of alternative already, and the issue with them is the userbase. No wonder that Whatsapp is still one of the most used services.

Now, in my proposition here, I would like to say that in my opinion "ProtonChat" should yes exist, but not as a standalone thing with proprietary protocol. It would be great to implement the well known Matrix Protocol (https://matrix.org/blog/home/) in order to enable end-to-end chat and calls (straight on the web version, and maybe implemented through the bridge).

This would allow all the ProtonMail users to communicate in other ways compared to E-Mail only, and still with other users/apps (like the famous Riot). And last but not least, it will make a lot of people aware of other services for communication, and help "make the switch" to them (in this case to the Matrix protocol).

What are your opinions?

Anyone of is in agreeance with my sentiments can place their votes here:

I wish this service had a vote DOWN button.

There are sufficient alternatives out in the wilds of the internet to deliver this requirement.

All this does is distract the Proton Dev people and push precious resources onto frivolous projects when they should be focusing on their core service that we have already paid for, being EMAIL ...that is still deficient in so many areas.

Grrr

Considering the upheaval that WhatsApp is involved in would it be possible for you to come up with a Secure Messaging Facility / App to compliment your already excellent email and VPN facility...

Assalamualaikum, saya ingin mendapat kepastian limit kilometer untuk minyak enjin fully synthetic adalah 10000km tetapi saya ingin mengetahui limit untuk sehingga membatalkan waranti kerete dengan pihak proton sebenarnya adlah berapa kilometer?

I'm with the many who recommend Signal, and we use it throughout our family.

WhatsApp may use Signal's protocol, but the servers at WhatsApp store your decryption key. This means your messages can be decrypted by coding errors, by crooked employees when curious or when payed off, or when the company forced to do so by the authorities.

If you are truly concerned about keeping your SMS messages private, I wouldn't recommend WhatsApp.

Then go back to FB!! Why are you even here? Social sites are expensive to run and rape your data. period.
