    The above commenter said that their end-to-end MTProto protocol is not enabled by default.

    Defaulting to just using transport encryption like TLS on a messaging app isn’t sufficient in 2024.

      MTProto is not end-to-end. MTProto is their obfuscated client-server transport encryption.

      What the commenter above is referring to is Telegram defaulting to saving your messages on the server in plaintext. You can use a “secret chat” which enables end-to-end encryption, but that is separate from MTProto.

      Your sentiment is correct though. Messages should not be visible in plaintext to the server.

          You’re right, it is misleading. There are different “flavours” of MTProto. See here:

          https://core.telegram.org/mtproto

          This page deals with the basic layer of MTProto encryption used for Cloud chats (server-client encryption). See also:

          • Secret chats, end-to-end-encryption

          • End-to-end encrypted Voice Calls

          (The major difference is simply whether the server and client share a key or two clients)
