Why CAI-AUTH?

🛡️ Quantum-Resistant

Hybrid Ed25519 + ML-DSA-65 signatures. If either algorithm falls (including to quantum), the other holds.

🔒 Hardware-Bound Keys

Private keys stored in StrongBox/TEE. Never leave the device hardware. Biometric-gated per operation.

⚡ Blazing Fast

Rust engine: <200ms signature latency, 78K requests/sec server. No compromises on speed.

📱 Push Authentication

Tap to approve on your phone. Post-quantum signed, not just a simple push. Like Duo but quantum-safe.

🔑 Passkeys PQC

First post-quantum passkey provider. WebAuthn compatible. Works with any website that supports passkeys.

💾 Encrypted Backup

PBKDF2 + AES-256-GCM encrypted backup. Server never sees your data. Restore on any device.

🔄 TOTP Compatible

Drop-in replacement for Google/Microsoft Authenticator. Scan QR, get codes. Plus post-quantum on top.

🏠 Self-Hosted

Run your own server. No vendor lock-in. Docker deploy in 5 minutes. Full sovereignty over your data.
