About
Montana Messenger is a private messenger sealed end to end with post-quantum cryptography: ML-KEM-768 and ML-DSA-65, the NIST standards designed to withstand quantum computers. Nothing readable leaves the devices of the conversation.
Write letters; send photos, videos, files and voice messages; call by voice or video. Sign in with a 24-word recovery phrase generated on your phone: no phone number or e-mail is required.
