It does, but only for chats between two specific devices. Multi-device support is one of its best features that you lose with E2E.
Key distribution is just too hard. I think we won't get a messenger for non-tech people that works well with multi-device and E2E basically ever.
- ymolodtsov 6mo agoIt's called iMessage. It's possible, Telegram just doesn't care. All their differentiating features (large groups, channels, device sync) is directly enabled by the lack of encryption.
- taminka 6mo agothey do have encryption, just not e2ee, and in fairness to them, it doesn't make sense to have e2ee on a channel or a group with 100k ppl in it, also device sync is possible with e2ee, it's just a slower
- tcfhgj 6mo agoyou can have large groups and device sync WITH e2ee, see Matrix.
- ymolodtsov 6mo agoAny Matrix client I tried lagged even without chats though.
- lxgr 6mo agoWhat are you talking about? WhatsApp, iMessage, and Signal all have multi-device support and are E2E encrypted, just to name a few very popular options.
- taminka 6mo agowhatsapp, facebook messenger, imessage all support multi-device and it's pretty convenient, in fairness to telegram they launched a bit before double ratched was invented, but still, they've had over a decade to switch to it...
- stavros 6mo agoWhatsApp doesn't support multi-device. You can't have it installed on two phones at once.
- taminka 6mo agoyou can (https://faq.whatsapp.com/1046791737425017/?cms_platform=android https://faq.whatsapp.com/1046791737425017/?cms_platform=andr...) they even have it on fb messenger and instagram (though they recently removed e2ee completely from instagram lol)
- stavros 6mo agoThat's still one device. If you turn the primary phone off, the secondary device stops working. WhatsApp just proxies everything through the primary device, it's like WhatsApp Web.
- taminka 6mo agooh, i see, is it the same for facebook messenger and instagram, imessage, etc?
- stavros 6mo agoI don't know, I don't use those. It is for Signal, I don't think so for Instagram, since I don't think that encrypts end to end.
- lxgr 6mo agoIt's not true for Signal either. Why don't you try it for yourself instead of spreading outdated (at best) information? Signal supports native multi-device capabilities without relaying everything through the "primary" device.
