Signal has considered all scenarios to prevent third parties from reading conversations, including the ability to use an older version of the client to receive messages in plain text. Whatsapp users can make sure your chats with your contacts are encrypted. The client uses QR codes scanned or a string of numbers that are used by both sender and receiver.
