Mixin Messenger is a free, open-source messaging application designed for secure communication across desktop and mobile devices. Its Flutter-based client supports Windows, macOS, Linux, and iPadOS. The software uses the Signal Protocol to provide end-to-end encryption for messages, photos, audio, and shared files. Users can participate in private conversations and group chats while maintaining control over their communication privacy. It supports voice calls, disappearing messages, and customizable chat settings. Desktop authentication uses QR code pairing with an existing mobile account. The application also provides message delivery indicators, contact management, and sticker sharing. Unlike the mobile wallet, the desktop version focuses on encrypted messaging rather than cryptocurrency management.
