Access-first authentication infrastructure designed for secure, real-time authorization.

Toqen is a system for secure access confirmation using QR-based flows and device-bound cryptography.

It enables instant authorization without exposing sensitive data and keeps control on the user’s device.

• Access-first architecture
• Device-bound authentication
• Minimal data exposure
• Real-time authorization
• Cryptographic verification

1. A service generates a temporary access request
2. A QR code is displayed with a short-lived challenge
3. The user scans the QR with the Toqen mobile app
4. The device signs the challenge using a private key
5. The server verifies the signature and grants access

• No reusable tokens
• No static QR codes
• Short-lived challenges (TTL)
• Device-based signature verification
• Encrypted local storage (vault)

• Secure login (QR-based)
• Access confirmation for sensitive actions
• Vault access approval
• Multi-device authorization
• Offline access tokens

Building continues.
