Open-source, encrypted 2FA token manager for desktop.

• TOTP tokens — 6, 7, or 8-digit codes with real-time circular countdown
• AES-256-GCM encryption — Secrets encrypted at rest, keys in your OS keychain
• Cross-device sync — Encrypted backups via any cloud folder (Dropbox, Drive, OneDrive)
• Auto-sync — Background sync when tokens change, with password mismatch recovery
• Import & export — Password-protected backup files, legacy format support
• Native & lightweight — ~5MB, built with Tauri 2 and Rust
• Fully offline — No accounts, no telemetry, no network calls

All cryptographic operations run in Rust via the audited ring library.

• Encryption key stored in OS keychain (macOS Keychain, Windows Credential Manager, Linux Secret Service) with encrypted file fallback
• Sync backups protected with PBKDF2-SHA256 at 600,000 iterations + AES-256-GCM
• Zero network calls — sync works via local filesystem only
• Minimum 8-character passwords enforced for sync and export
• Secret cache TTL — decrypted secrets expire from memory after 5 minutes

• Rust 1.77+
