Features
Living off the land - CNG, DPAPI, Windows Hello, and a local vault file you control. No subscription required for Personal.
Credentials live in vault.fva on your PC or USB. AES-256-GCM via Windows CNG. Master password never leaves your device.
Memory-hard KDF (64 MB / 3 iter / 4 lanes on Personal). Vault key wrapped with MK and protected by DPAPI at rest.
Unlock with face, fingerprint, or PIN via a DPAPI-protected key protector. Master password remains the recovery root.
Full scan: weak, reused, and missing passwords, settings hygiene, duplicates, and vault health. Export JSON or HTML - never secrets.
Chrome and Edge extension with manual Fill only. Connect once in Settings → Connect browser; while unlocked, Fill uses loopback HTTP at 127.0.0.1:7847 with a native-messaging fallback.
Detects vault rollback via revision counter and DPAPI state. Suspicious downgrade opens read-only until you confirm in Settings.
Migrate from KeePass CSV, browser exports, Apple Keychain CSV, or generic CSV. Encrypted .fva / .fvab backups with preview and duplicate scan.
Personal edition can open or create a vault directly on removable media - credentials travel on your USB, Hello tokens stay on the host PC.
Timestamped unlock, lock, and browser-bridge events. Export JSON for your own review - never secrets.
Why Fortiva
Fortiva is designed for people who want Windows-native security without handing credentials to a remote service.
Your vault file (vault.fva) stays on disk you control. Five rolling encrypted snapshots protect against corruption. No sync servers, no accounts.
WinUI 3 and self-contained .NET 8 - not Electron. Crypto through Windows CNG, secrets through DPAPI, unlock through Windows Hello and optional TPM.
The Fortiva Autofill extension never injects credentials on page load. Connect it once in Settings, then click Fill - the app verifies hostname match and serves credentials over localhost only.
No always-on background service. Panic lock hides the window instantly. Auto-lock and clipboard auto-clear keep secrets off the screen when you step away.
