In a landmark move for cross-platform communication, Google and Apple have jointly enabled end-to-end encryption (E2EE) for Rich Communication Services (RCS) messages between Android and iPhone users. This update, announced on May 12, 2026, ensures that text messages, images, videos, and other media shared between the two operating systems are now fully encrypted from sender to recipient.
Details of the Update
Previously, RCS messaging offered E2EE only within the same platform—Google Messages for Android or Apple's iMessage. Cross-platform chats relied on SMS/MMS, which lack encryption. The new implementation uses the Messaging Layer Security (MLS) protocol, endorsed by the Internet Engineering Task Force (IETF), to provide robust encryption without compromising performance.
Users on both platforms will now see a lock icon next to the send button when exchanging RCS messages, indicating that the conversation is encrypted. Read receipts and typing indicators are also supported in these encrypted chats.
How It Works
The MLS protocol enables group key agreements and message encryption that scales efficiently even for large group chats. Google Messages and Apple's Messages app have been updated to support the new standard. Users need to ensure they have the latest version of their respective messaging apps to take advantage of the feature.
- Android Users: Update Google Messages via the Play Store. The feature will automatically enable for RCS chats with iPhone users.
- iPhone Users: Update to the latest iOS version and ensure Messages app is set to use RCS. The feature works out of the box.
Impact on Privacy
This development addresses a long-standing privacy gap. Previously, cross-platform texts could be intercepted or read by carriers. With E2EE, only the sender and recipient can read the messages. Law enforcement and third parties are effectively blocked from accessing content.
Privacy advocates have praised the move, noting that it covers billions of users globally. However, some experts caution that metadata (such as who is communicating and when) remains visible to service providers.
Rollout Timeline
The feature is rolling out globally starting today. Google and Apple expect full availability within two weeks. The update does not affect existing SMS/MMS conversations unless both parties have RCS enabled.
This collaboration marks a significant step toward universal secure messaging, setting a new standard for interoperability and user privacy.
