01
The decision in brief
Choose on the job in front of you. If it is integrating many kinds of login across many applications, Auth0's breadth wins. If it is removing passwords from sign-in and helpdesk resets, SenseCrypt IdP does that job, and it can do it behind Auth0 without replacing it.
Choose Auth0 when
you need many connection types, social and enterprise logins, and an extensibility model your developers can bend around unusual requirements.
Choose SenseCrypt IdP when
you want end-user sign-in without a password to steal or reset, with a live face check on the enrolled phone and a passkey method where origin binding is required.
Side by side
| Dimension | SenseCrypt IdP | Auth0 |
|---|---|---|
| What you buy | An identity provider built around a live face check | A developer identity platform with many connection types |
| End-user sign-in | QR or passkey in the SenseCrypt Authenticator app; no password | Configurable: passwords, social, enterprise, one-time codes, passkeys |
| Phishing resistance | On the passkey method, via FIDO2/WebAuthn origin binding | Passkeys supported; depends on the methods you enable |
| Working together | Registers in Auth0 as an external IdP (OIDC or SAML 2.0) | Accepts external identity providers |
| List price | $1 per user per month; 20-seat minimum | Varies by plan |

Broad platform or focused sign-in?
Auth0 gives an engineering team many ways to sign a person in: passwords, social connections, enterprise connections, one-time codes and passkeys. That range is the product, and it is why Auth0 fits so many applications.
SenseCrypt IdP takes a narrower position. It offers a QR method and a WebAuthn passkey method in the app, plus a licensed webcam method for enterprise deployments, and you select the method by the assurance and deployment model you need. What it does not offer is a password. The 2026 Verizon DBIR attributes credentials to 28 percent of breaches, and a password kept for recovery brings that exposure back.
Methods differ in strength
The passkey method is phishing-resistant through FIDO2/WebAuthn origin binding. The QR method removes password entry but is not origin-bound. The webcam method has no phone possession factor. All three share the live face check.
The target device needs no enrollment
On both phone methods, liveness and matching run on the user's own handset. The browser, kiosk or shared desktop being signed in to needs no enrollment, no agent and no driver.
Plan for enrollment
On the phone methods, each user installs the app and binds a phone they will actually carry. Budget that as change management with a helpdesk plan behind it; it is the real cost line on a rollout.

Running both, with SenseCrypt IdP behind Auth0
Replacing the platform that already holds your applications, users and audit history is rarely proportionate to a change in sign-in method, and this page does not argue for it. Auth0 supports external identity providers over OIDC or SAML 2.0, and SenseCrypt IdP registers as one of them.
Auth0 remains the identity platform in that arrangement: it holds the user records, the rules, the application registrations and the session it issues. Only the proof step moves. A user arriving at Auth0 is passed to SenseCrypt IdP, completes the face check on the enrolled phone, and returns with a standard token or assertion that Auth0 turns into the application session it always issued.
Setup is configuration on both sides, with no connector to install: register Auth0 as an OIDC application in SenseCrypt IdP, attach the groups that may use it, map the claims, and decide in Auth0 who takes the new path.
Keep existing application integrations
Applications keep pointing at Auth0. There is no SDK to swap and no redirect URI to update in every service.
Pilot with one group
Point one application, or one department, at the new path and leave everyone else untouched. The support queue answers the enrollment question before a full rollout is committed.
Map the incoming claims
SenseCrypt IdP emits roles and permissions in the token. Auth0 maps them into its own model, and your application keeps enforcing what it already enforced.

Frequently asked questions
Is SenseCrypt IdP an alternative to Auth0 or an addition to it?
Both patterns work, and the second is the more common starting point. Applications can federate to SenseCrypt IdP directly over OIDC or SAML 2.0. It can also register behind Auth0 as an external identity provider, which leaves your directory, rules and application registrations untouched and changes only how a user proves presence.
Is SenseCrypt IdP phishing-resistant?
On the passkey method, yes. Those are FIDO2/WebAuthn passkeys, and origin binding is what makes a lookalike site unusable, which is the pattern CISA points to in its phishing-resistant MFA guidance. The QR method removes password entry but is not origin-bound, so require the passkey method where origin-bound phishing resistance is needed.
Does every user need a phone?
For the QR and passkey methods, yes: the SenseCrypt Authenticator app on an enrolled phone is required whenever a fresh face ceremony is needed; session reuse depends on the tenant's persistence setting in the IdP portal. What needs no enrollment is the target, the browser, kiosk or desktop the user signs in to. Enterprise customers can license the Simple Webcam method, a deviceless mode that uses a webcam and no phone; it runs on secure terminals and does not add an enrolled-phone possession factor. Ask sales@seventhsense.ai.
What happens when a user loses their phone?
They bind a replacement through a verified contact, a one-time PIN by email with an SMS copy where a number is on file, and the new phone proves a new device key. The face is not re-registered, and the live face check is still required at sign-in. There is no end-user password for a helpdesk to reset.
