"Ensuring Safe Interoperability: Meta's Plan for WhatsApp and Messenger Integration with Third-Party Services in Europe"
In compliance with the new EU law, the Digital Markets Act (DMA), WhatsApp and Messenger are making changes to enable interoperability with third-party messaging services while maintaining end-to-end encryption and privacy guarantees. The law requires designated messaging services to allow third-party interoperability, enabling users to send and receive messages with opted-in users of either Messenger or WhatsApp. The implementation of interoperability focuses on preserving privacy and security, utilizing the Signal Protocol for encryption, and building on Meta's existing client/server architecture. Meta emphasizes the importance of transparently informing users about the differences in security and privacy when communicating with third-party providers.
