SDKs & apps
The SenseCrypt Authenticator mobile app for end users, the Mobile SDK for building your own, and how to integrate your own web application as a relying party.
There are two sides to a SenseCrypt integration: the end-user app that performs the biometric ceremony, and your application that speaks OIDC or SAML.
A live-face check proves the person in every ceremony; on the passkey method a real FIDO2/WebAuthn passkey (ES256) proves the device. See How SenseCrypt works for the three sign-in methods (Simple QR, passkeys, and the enterprise Simple Webcam).
For end users: the Authenticator app
The SenseCrypt Authenticator is the mobile app (iOS and Android) your users install to approve sign-ins with a face scan. It is the end-user app — you do not embed it in your product. Your users install it from the App Store or Google Play.
A tenant can instead run its own app: a rebuild of the Authenticator, or an app of your own built on the SDK, distributed under your own developer accounts. The server verifies that app once the tenant registers it on the console's Mobile App page. See Ship your own Authenticator app.
For your own app: the Mobile SDK
The Mobile SDK embeds the same device-bound keys, on-device face matching and authentication flows in your own iOS or Android app. It is provided on request, not published publicly. Most integrations do not need it.
For your application: relying party
Your web app integrates as a standard OIDC relying party (or a SAML SP). You do not need a SenseCrypt-specific SDK — any conformant OIDC/SAML client library works. See Relying party for how to think about it, then the Add Login quickstart for the concrete steps.

The SenseCrypt Authenticator app for iOS and Android — the end-user app that approves sign-ins and key requests with a face scan. Most integrations use it as-is rather than embedding anything.
