🔐 Dual-Authority Protection

The vault that opens only when two agree

VaultDuo is the world's first digital vault requiring simultaneous biometric authentication from two authorized parties — no single point of access, ever.

Live Authentication Session
👤
Primary Owner Face ID confirmed
+ simultaneous confirmation required
🛡️
Trusted Guardian Face ID confirmed
Vault unlocked · Dual consent verified
2-of-2 Authentication required
AES-256 Encryption standard
0 Single-party overrides possible
100% Biometric — no passwords

Simple in use.
Impossible to bypass.

Three straightforward steps stand between your most sensitive information and anyone who shouldn't have access.

STEP 01 🔗

Pair Your Guardian

Link a trusted individual as your vault co-holder. They receive their own secure credential — completely independent from yours.

STEP 02 📲

Request Access

When you need to open the vault, a real-time authentication request is sent to both parties simultaneously, wherever they are.

STEP 03

Both Must Confirm

Only when both parties authenticate with Face ID within the same session does the vault open. Either alone grants nothing.

Capabilities

Everything you need.
Nothing you don't.

🧬

Biometric Dual Authentication

Face ID from both parties must be confirmed in real time. No passwords, no PINs — only biometric certainty from both sides.

🔑

Shamir Secret Sharing

Your vault key is mathematically split between both parties using military-grade cryptography. Neither half alone has any value.

📁

Encrypted File Storage

Documents, photos, and sensitive files stored with AES-256-GCM encryption — completely unreadable without dual consent.

🌍

Remote Access

Both parties can be anywhere in the world. Authentication is instant, synchronized, and requires no physical proximity.

📋

Full Audit Trail

Every access attempt, successful or not, is logged with timestamp, device, and biometric confirmation — complete traceability.

Instant Revocation

Remove a guardian's access in seconds. The vault immediately becomes inaccessible until a new trusted party is paired.

Built for those with
the most to protect.
