Okta manages workforce SSO and customer identity. H33 secures the cryptographic layer underneath with post-quantum encryption. If your threat model includes quantum computing, harvest-now-decrypt-later attacks, or zero-trust compliance mandates, H33 is the Okta alternative engineered for what comes next.
An “Okta alternative”, in H33’s framing, is a post-quantum cryptographic authentication layer that proves an identity or authorization claim without exposing the credential behind it — a supporting expression of the ZK Platform, which proves without revealing. This page exists to help teams evaluating post-quantum, harvest-now-decrypt-later, or zero-data-exposure requirements understand how a cryptographic verification layer compares to a full identity-management suite.
When to choose this: reach for H33's cryptographic verification layer when your priority is post-quantum, harvest-now-decrypt-later resistance, or proving an authentication claim without exposing the underlying secret. When not to: if you need a full identity-management suite — directory, lifecycle/provisioning, and broad SaaS integrations — a dedicated IAM platform such as Okta is the better fit; H33 verifies claims, it is not a directory or the authority that decides what a user may do (that is governed by Agent-008 under authority preserved by Authority Center).
What is not claimed: H33 is not a feature-for-feature substitute for Okta’s directory, user lifecycle, SSO orchestration, or admin tooling, and the comparisons below are limited to the cryptographic authentication layer. Okta capabilities are described from publicly documented behavior as of 2026; where a claim could change, it is dated. H33 is designed to run alongside an identity provider, not necessarily to rip and replace one.
How an enterprise identity platform compares to a post-quantum cryptographic authentication API.
| Feature | Okta | H33 |
|---|---|---|
| Identity Management Approach | Workforce SSO + Customer Identity (directory, lifecycle, MFA orchestration) | Post-quantum cryptographic authentication API — FHE + ZKP + PQ signatures |
| Post-Quantum Crypto | No — RSA/ECDSA for token signing, TLS for transport | ML-KEM (Kyber) + ML-DSA (Dilithium) — NIST FIPS 203/204 |
| Encrypted Biometrics | Delegates to third-party MFA providers (WebAuthn, FIDO2) | BFV lattice FHE — biometric matching without decryption (937µs / 32 users) |
| Zero-Knowledge Proofs | Not offered | ZK-STARKs with SHA3-256 — 2.0µs prove, 0.2µs verify |
| Throughput | Rate-limited per tenant (varies by plan) | 2.21M auth/sec sustained (Graviton4, 96 workers) |
| Per-Auth Latency | Network-bound (100–500ms typical with SSO redirect) | ~35.25µs per auth (batched FHE + ZKP + attestation) |
| Pricing Model | Per user per month ($2–15+/user/mo depending on product) | from $0.001 per authentication at scale — pay for what you use |
| Data Exposure During Auth | Credentials processed in plaintext on Okta servers | Zero — FHE computation on encrypted data only |
Okta 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 (Kyber) for key exchange and ML-DSA (Dilithium) for digital signatures, plus nested hybrid signatures (Ed25519 + Dilithium). No migration later — you start quantum-safe from day one.
Okta decrypts credentials server-side to verify them. H33 performs the entire verification in FHE ciphertext space — biometric templates are matched inside BFV encryption at 937µs per 32-user batch. The server never sees plaintext. A breach of H33 infrastructure exposes only encrypted ciphertexts that are computationally infeasible to decrypt.
Okta stores identity in a centralized directory. H33 supports soulbound decentralized identity (DID) — non-transferable, cryptographically bound credentials anchored on-chain. Your identity cannot be revoked by a provider outage, admin error, or account takeover. ZK-STARK proofs verify attributes without revealing underlying data.
Benchmarked at 2.21 million authentications per second sustained on AWS Graviton4. Each auth includes FHE biometric matching, a ZK-STARK proof, and a Dilithium digital signature — all completed in approximately 36 microseconds. This exceeds the throughput ceiling of most Okta enterprise deployments, and every operation is post-quantum secure.
Standard SSO authentication vs. post-quantum encrypted verification.
// Okta: credentials sent to Okta servers const { OktaAuth } = require('@okta/okta-auth-js'); const authClient = new OktaAuth({ issuer: 'https://your-org.okta.com/oauth2/default', clientId: 'YOUR_CLIENT_ID' }); const result = await authClient.signInWithCredentials({ username: 'user@example.com', password: 'plaintext-password' }); // Server decrypts and compares credentials // JWT signed with RS256 (RSA-2048)
// 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 ~937µs (32 users/batch) // Plaintext NEVER touches the server // All signatures are post-quantum (ML-DSA)
