RCS Messaging Gets End-to-End Encryption: A Major Security Upgrade

After months of anticipation, RCS messaging has received a major update: end-to-end encryption (E2EE). Based on the MLS protocol, this upgrade ensures the security and confidentiality of RCS messages between iOS and Android devices. Google's RCS already supported E2EE, but only if all participants used Google Messages with RCS chats enabled. Apple also contributed to this industry effort and has pledged to add E2EE support to iOS, iPadOS, macOS, and watchOS in future software updates, further enhancing message security and preventing third parties from intercepting sensitive information.
