Proton launched Meet, a privacy-first video conferencing service offering end-to-end encrypted calls as a free option for one-hour meetings with up to 50 participants and a Pro plan starting at $7.99/month. Built on WebRTC with Selective Forwarding Units and using the open-source Messaging Layer Security (MLS) and Secure Remote Password (SRP) for authentication, Meet keeps media and chat encrypted client-side, exposes only meeting IDs on servers, and offers mitigations if meeting links are compromised. #ProtonMeet #MessagingLayerSecurity
