"WhatsApp to Enable Cross-App Chatting with Encrypted Messaging Platforms"

WhatsApp is preparing to enable cross-messaging with other platforms, allowing users to chat with people using Signal, Telegram, and other messaging services. Users will need to opt in to this feature, and third-party app chats will be placed in a separate inbox due to potential differences in privacy and security standards. Third-party services will need to sign agreements with Meta to ensure interoperability, and may need to adopt the Signal encryption protocol. While this interoperability is on the horizon, it may take time for other services to join Meta's platforms, and the integration may not be as seamless as initially hoped.
