Features

Built for serious Windows security

Living off the land - CNG, DPAPI, Windows Hello, and a local vault file you control. No subscription required for Personal.

Zero-knowledge vault

Credentials live in vault.fva on your PC or USB. AES-256-GCM via Windows CNG. Master password never leaves your device.

Argon2id key derivation

Memory-hard KDF (64 MB / 3 iter / 4 lanes on Personal). Vault key wrapped with MK and protected by DPAPI at rest.

Windows Hello

Unlock with face, fingerprint, or PIN via a DPAPI-protected key protector. Master password remains the recovery root.

Security audit

Full scan: weak, reused, and missing passwords, settings hygiene, duplicates, and vault health. Export JSON or HTML - never secrets.

Fortiva Autofill

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.

Paranoia mode

Detects vault rollback via revision counter and DPAPI state. Suspicious downgrade opens read-only until you confirm in Settings.

Import & export

Migrate from KeePass CSV, browser exports, Apple Keychain CSV, or generic CSV. Encrypted .fva / .fvab backups with preview and duplicate scan.

Portable USB vault

Personal edition can open or create a vault directly on removable media - credentials travel on your USB, Hello tokens stay on the host PC.

Audit log

Timestamped unlock, lock, and browser-bridge events. Export JSON for your own review - never secrets.

Why Fortiva

Not another cloud password manager

Fortiva is designed for people who want Windows-native security without handing credentials to a remote service.

Local-first by design

Your vault file (vault.fva) stays on disk you control. Five rolling encrypted snapshots protect against corruption. No sync servers, no accounts.

Living off the land

WinUI 3 and self-contained .NET 8 - not Electron. Crypto through Windows CNG, secrets through DPAPI, unlock through Windows Hello and optional TPM.

You choose when to Fill

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.

Runs when you open it

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.

Key hierarchy

  1. Master password

  3. AES-256-GCM wraps Vault Key
