KEYON :2FA AUTHENTICATOR NINJA
KEYON is a next-generation 2FA (Two-Factor Authentication) vault built for uncompromising privacy and blazing performance. Powered by a highly optimized native Rust cryptography core, KEYON keeps your digital identity strictly in your control.
There are no central servers holding your keys. There are no mandatory accounts. Your data never leaves your device unencrypted.
ZERO-KNOWLEDGE ARCHITECTURE
Your 2FA secrets are encrypted on-device using military-grade AES-GCM encryption. KEYON utilizes a zero-knowledge architecture—we do not want your data, and we cannot read it.
NO ACCOUNTS, NO TRACKING
Skip the sign-up screens. KEYON requires no email, no phone number, and no cloud account. It operates entirely offline by default, acting as a secure, air-gapped vault in your pocket.
AIR-GAPPED & P2P DEVICE SYNC
Syncing your 2FA codes across multiple devices has never been safer:
• Air-Gapped QR Sync: Broadcast your entire encrypted vault visually via high-speed QR chunks. Transfer data to an offline device without a single byte crossing the internet.
• Peer-to-Peer Cloud Sync: Generate a secure pairing room. Devices sync via a sovereign, end-to-end encrypted WebSocket mesh. Keys are never stored on a relay server.
BULLETPROOF RECOVERY
Never lose your accounts. KEYON supports secure, password-protected file exports (seed/backup files). Import existing vaults effortlessly from text seeds or legacy authenticator backups.
BUILT FOR PERFORMANCE
• Rust Core: Cryptography and sync manifests are handled by a memory-safe, ultra-fast Rust engine.
• Native Rendering: The 120-FPS zero-recomposition UI draws TOTP timers directly to the canvas, bypassing standard UI bottlenecks for buttery-smooth performance.
• AMOLED Dark Mode: A pitch-black UI designed for OLED battery efficiency and low-light stealth.
• Biometric Lock: Secure your vault with local fingerprint/biometric hardware limits.
