About this app

Keyo is a open-source password manager for Android built with Zero-Knowledge architecture.
Your passwords, logins, and notes are encrypted directly on your device using AES-256-GCM before being synced to the cloud. Your master password is never transmitted over the network or stored on any server.
Features:
• Zero-Knowledge encryption — we cannot read your data
• AES-256-GCM with unique IVs for every entry
• Argon2id key derivation to resist hardware brute-force attacks
• Cloud sync via Firebase with real-time updates across devices
• Auto-lock with full key wiping from RAM
