Building over eitland's reply, Telegram allows users to see messages on several devices. This is because they terminate encryption on their servers and can send a copy of the plaintext message (re-encrypted) to every other device of the same user. They also store a copy because you can start from scratch with no surviving devices and a brand new one. All you need is access to your account. E2E chats work only on one device and are invisible to the other devices of the user [1]. More technical details at [2]

- mort96 4y agoEssentially it just means that the connection between the app and the server is encrypted à la HTTPS, right?
- pmontra 4y agoRight. With E2E they receive encrypted data, with point to point they get plain text.
- eitland 4y agoI think this can be misunderstood in at least two ways. My most understanding reading is that you mean Telegram receives the data in plain text at their servers. That reading implies that they don't do this whole "encrypted data one way, keys another way" thing. (If we know they don't do that I am interested in knowing.) But a number of people here on HN will read it as "Telegram sends data unencrypted", which is definitely incorrect.
