Auth0 manages login flows. H33 secures the cryptographic layer underneath. If your threat model includes quantum computing, data breach liability, or regulatory requirements for encrypted credential processing, H33 is the Auth0 alternative built for what comes next.
How a traditional identity platform compares to a post-quantum cryptographic authentication API.
| Feature | Auth0 | H33 |
|---|---|---|
| Post-Quantum Crypto | No — RSA/ECDSA only | ML-KEM (Kyber) + ML-DSA (Dilithium) — NIST FIPS 203/204 |
| FHE Biometric Matching | Not offered | BFV lattice FHE — verification without decryption |
| Zero-Knowledge Proofs | Not offered | ZK-STARKs with SHA3-256 — post-quantum secure |
| Nested Signatures | Single JWT signature (RS256 / ES256) | 3-key nested: Dilithium + Kyber + attestation hash |
| Throughput | Varies by plan and region | 2.17M auth/sec sustained (Graviton4, 96 workers) |
| Per-Auth Latency | Network-bound (50–200ms typical) | ~38.5µs per auth (batched FHE + ZKP + attestation) |
| Pricing Model | Per monthly active user (MAU) | $0.033 per authentication — pay for what you use |
| Data Exposure During Auth | Credentials decrypted on server for verification | Zero — FHE computation on encrypted data only |
Auth0 relies on RSA and ECDSA, which are broken by Shor's algorithm on a sufficiently powerful quantum computer. H33 uses NIST-standardized lattice-based cryptography (ML-KEM and ML-DSA) for every authentication. No migration later — you start quantum-safe from day one.
Benchmarked at 2.17 million authentications per second sustained on AWS Graviton4. Each authentication includes FHE biometric matching, a ZK-STARK proof, and a Dilithium digital signature — all completed in approximately 36 microseconds per auth.
Auth0 decrypts credentials server-side to verify them. H33 performs the entire verification in FHE ciphertext space. The server never sees plaintext biometrics or credentials. A breach of H33 infrastructure exposes only encrypted ciphertexts — computationally infeasible to decrypt.
Auth0 charges per monthly active user, which means you pay for dormant accounts. H33 charges $0.033 per authentication with volume discounts. You pay only for actual cryptographic operations — no cost for users who do not authenticate in a given period.
Standard credential verification vs. post-quantum encrypted authentication.
// Auth0: credentials decrypted on server const { AuthenticationClient } = require('auth0'); const auth0 = new AuthenticationClient({ domain: 'your-tenant.auth0.com', clientId: 'YOUR_CLIENT_ID' }); const result = await auth0.passwordGrant({ username: 'user@example.com', password: 'plaintext-password', scope: 'openid profile' }); // Server decrypts and compares credentials // JWT signed with RSA-256 or ECDSA
// H33: credentials never decrypted const result = await h33.authenticate({ biometric: capturedTemplate, securityLevel: 'h33-128', mode: 'standard' }); // result.verified → true / false // result.attestation → Dilithium-signed proof // result.zkProof → ZK-STARK verification // // FHE biometric match in ~939µs (32 users/batch) // Plaintext NEVER touches the server // All signatures are post-quantum (ML-DSA)
