Security and Privacy Foundations
End-to-end encryption sits at the core of both Signal and Telegram—but how they implement it diverges significantly.
-
Signal’s Default E2EE: Every one-to-one conversation and group chat on Signal uses the Signal Protocol for true end-to-end encryption. This means only you and your intended recipients can read messages—Signal’s servers hold no decryptable copies.
-
Telegram’s Selective Encryption: Telegram offers “Secret Chats” that employ MTProto encryption end-to-end, but regular cloud chats use server-client encryption, allowing Telegram to store your messages encrypted on their servers.
When comparing signal vs telegram, privacy purists often favor Signal’s blanket E2EE. However, Telegram’s cloud chats enable multi-device sync and media backup—features absent from Signal’s infrastructure.
