Google takes first major step: E2EE interoperability across all messaging apps

Google Messages is incorporating code related to Messaging Layer Security (MLS), indicating upcoming support for encrypted group messaging. MLS, a standard endorsed by Google last year, aims to ensure end-to-end encrypted messages remain secure in group chats across various apps and platforms. The inclusion of MLS in Google Messages could promote its adoption, similar to how Google drove the adoption of RCS. The Internet Engineering Task Force developed MLS to address the challenge of E2EE group messaging. While the exact integration of MLS into Messages is yet to be revealed, the presence of MLS references in the app suggests a move towards more secure communication. Google's proactive stance on MLS could signal support for open messaging and interoperability, especially in regions like the EU where regulators push for such measures. As Google continues to pave the way for MLS in its apps, the future of cross-platform messaging, including potential benefits and challenges of MLS, remains to be seen.
