**Discord**, a popular communication platform boasting an estimated 690 million registered users and over 200 million monthly active users, has officially rolled out end-to-end encryption (E2EE) for all voice and video calls. ## Universal Encryption with DAVE The migration to E2EE was achieved by extending the open-source encryption protocol **DAVE** to support all platforms where **Discord** clients operate. This includes desktop, mobile, web browsers, **PlayStation**, **Xbox**, and **Discord** SDKs. The encryption now covers DMs, group DMs, voice channels, and Go Live streams. Stage channels remain the only exception due to their design for large public broadcasts. "End-to-end Encryption is now standard for every voice and video call on **Discord**, outside of stage channels. No opt-in required," **Discord** stated in a blog post. **DAVE** was initially introduced in September 2024 and developed with assistance and auditing from **Trail of Bits**. The protocol leverages WebRTC encoded transforms, Messaging Layer Security (MLS) for scalable group key exchanges, and ephemeral identity keys to enhance privacy and minimize call disruptions and latency. ## Overcoming Technical Challenges **Discord** highlighted the technical hurdles in extending **DAVE** to all supported platforms while maintaining low-latency levels. One notable challenge was compatibility with **Firefox**, which **Discord** addressed by collaborating with **Mozilla** to resolve the issue. ## No Plans for Text Encryption Regarding the potential expansion of **DAVE** to text-based communications, **Discord** has stated that there are currently no plans for such an implementation. The company cites significant engineering challenges due to the existing architecture of **Discord's** text features, which were built around non-encrypted messaging assumptions.
