Obelisk vs Auth0, honestly
Auth0 (now part of Okta) is the incumbent developer-facing identity platform — deeply flexible, broadly adopted, with a huge connector and extensibility ecosystem. Obelisk is a passkey-first identity and security plane built around one idea: security you can prove, not just promise. This page compares the two fairly — Auth0 is a genuinely good product for teams who want a mature, highly configurable IAM platform with a large ecosystem, and we say so plainly below.
The short version: if your priority is provable security on the login itself — a live Rating, tamper-evident receipts, passkey-first by default, and zero secrets in your own app — Obelisk is built for exactly that. See the full field →
Where Auth0 shines
Auth0 earned its place: an enormous library of social and enterprise connections, deep extensibility (rules, actions, hooks), wide protocol support, and years of production hardening across every industry. If you need maximum configurability and a vast integration ecosystem from a household-name vendor, Auth0 is a proven choice.
Side-by-side: Obelisk vs Auth0
Obelisk's column is stated as fact — these are shipped, live features. Auth0's column reflects its public positioning as of 2026; vendor capabilities and pricing change, so verify the latest from their docs.
| Dimension | Obelisk | Auth0 |
|---|---|---|
| Default auth method | Passkey-first / passwordless by default | Username/password + extensive social/enterprise; passkeys supported, as of 2026 |
| Live security score on login | Yes — the Obelisk Rating, real-time, on the login surface | Not a feature, based on public positioning |
| Tamper-evident receipts | Hash-chained, signed receipts; the chain can't be silently rewritten | Comprehensive logs/streams, based on public docs |
| Project-side secrets | Zero — apps hold no credentials | App holds client secret(s), per standard OIDC integration |
| OIDC + SAML 2.0 IdP | Both, first-class | Both, mature — a core strength of Auth0 |
| Pricing model | Pay per audited passage (sign-in) | Per monthly-active-user / tiered, based on public pricing |
| Risk engine | The Warden — 11-dimension real-time decisioning | Attack protection / adaptive MFA, based on public docs |
| Never-lockout + off-box DR | Guaranteed; ~15-min recovery-time objective | Standard managed-service SLAs, based on public docs |
| Post-quantum readiness | Documented PQC migration path in every receipt chain | Not publicly positioned, as of 2026 |
| Operating model | Private, proprietary, single accountable studio | Large managed platform (Okta), based on public positioning |
Why teams choose Obelisk
The differences below aren't cosmetic — they're structural choices that move security from "trust us" to "verify it."
- Passkey-first by default. Passwordless via WebAuthn/FIDO2 is the default path, not an add-on — the secret half of the credential never leaves the device, so it can't be phished, stuffed, or stolen from a database.
- A live security Rating on the login itself. The Obelisk Rating is a real-time 0–100 security score shown on the sign-in surface — verifiable and continuously scored. No other identity provider renders a live security score on the login.
- Tamper-evident, hash-chained receipts. Every sign-in, token, and grant emits a signed, hash-chained receipt. The chain can't be quietly rewritten, so the audit trail is something you can verify, not just trust.
- Zero project-side secrets — one-DB model. Relying-party apps hold no credentials. Your app stores no password hashes, MFA seeds, or reset tokens, because Obelisk hands you a verified identity. You can't leak what you don't store.
- Off-box DR + never-lockout guarantee. Encrypted off-box disaster-recovery backups give a recovery-time objective of ~15 minutes, and a three-layer never-lockout guarantee means the rightful owner is never locked out.
- Pay-per-passage pricing. The Gate Toll bills per audited sign-in (a passage), not per seat or per monthly-active-user — and every billable passage is itself a signed receipt.
Together these make the login the strongest part of your stack, with a posture anyone can check. See the full trust case →
Frequently asked questions
Is Obelisk an Auth0 alternative?
Yes. Auth0 is a broad, highly configurable IAM platform; Obelisk is a focused, passkey-first identity plane that emphasizes provable security — a live Rating on the login, hash-chained receipts, and zero project-side secrets. For teams who value security posture and auditability over maximum configurability, Obelisk is a strong alternative.
Can I migrate from Auth0 to Obelisk?
Yes. Both speak standard OpenID Connect, so the integration shape is familiar: register your app, send users to Obelisk to authenticate, verify the ID token, and map the subject id to your records. Obelisk's pricing is per-passage rather than per-MAU — so you pay for active, audited sign-ins, not dormant seats, and the one toll covers the whole platform (the Rating, receipts, the Warden, never-lockout), not auth alone.
How does Obelisk pricing compare to Auth0's?
Auth0 bills broadly per monthly-active-user. Obelisk bills per audited passage — a successful, interactive sign-in — so you're not charged for dormant accounts, and every billable passage is a signed receipt you can audit. We compare models, not specific prices, since vendor pricing changes.
