There is a ‚perfect secure‘ Messenger out there already. Swiss-based and in contrast to signal completly anonymous..
please have a look at Threema.

What's wrong it Signal / Telegram / Wickr, and allow ProtonMail to focus on services where there doesn't already exist a good zero knowledge service?

and Video Calls Too

What if you merged with Signal? I know they'd have to agree but it would certainly be great to have the best encrypted messenger and the best encrypted email working together as one. All while being open-source, transparent and in the public interest. :)

Need to be able to chat similar to Google Hangouts with other proton mail account holders

Would love to see XMPP supported. It's one of the main reasons I, and probably many others, have not completely migrated over from services such as riseup.

please make this happen......

Guys.. You're thinking that the chat will have to be in ProtonMail. They can separate it into a seperate app/website like they did ProtonVPN! You don't have to use ProtonVPN if you don't want to! It would be great to have a secure, encrypted messaging platform. It doesn't need any of the fluff that other messaging/social networks have like stories etc. Just a simple contact to contact messenger. ProtonMail, if you're looking at this, contact me if you want input.

it´s planned and you could just use signal or threema or wikr... the problem is that there are already a lot of messengers with not many people to use them. and since there are not many people on them, new people won´t use it over whatsapp. more secure messengers won´t fix that problem.

Secure instant messaging between Proton Mail users only within Proton Mail or with a Smart Phone without a ton of permissions needed between Proton Mail users only.

> Possibly in 2016.

Or not.

Meanwhile, users should know that there are many encrypted chat programs. Signal for mobile (free and open source and with better implementation of key exchange than WhatsApp). Check out Wire (Swiss, free and open source) as a Skype alternative.

German government just announced to officially surveil WhatsApp. Please give us a secure messenger!!! ;-)

End2end inscription? :P Encryption. And it's already planned.

Perfect secure Messenger with end2end inscription. Why not make 2in1: mail+chat - simple but great idea! User ID is like JID user@pmail.com or user@pm.me :) Would be awesome! Thanks!

I would be interested in an app, which provides secure messaging between smartphone (something like a secure iMessage).

Add a Facebook messenger style chat in which you can save them in your account or copy content of the chat.

PLEASE DO THIS IT WOULD BE A GREAT ADDITION IT'S 2017 ALREADY AND THIS WOLD BE AMAZING TO HAVE !!!!!!!!!!!!!!!!!!!

Why should we be exlcuded from instant chat (texting) just because we don't have gmail or other services that have this feature.

Why should all our friends be able to do instant chat (texting) and not us? I think we should have this feature added.

I'm not sure if it makes sense for protonmail to implement this, given there are many other services targeting encrypted chat.

However, if you do want to implement a chat service, please consider using http://matrix.org/ rather than signal. Signal is great, but does not have federation. So it acts as a walled garden.

If you implement matrix, you can host your own chat servers but also then let users chat to users on other servers.

Matrix also has bridges, which allow you to connect other chat services e.g. IRC.

If you would like to see how matrix works, have a look at https://riot.im/ which implements the matrix protocol.
