🔐 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.

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.

the most to protect.
