Keycloak vs. Authsignal + Keycloak

Passkey Support

Built into the browser login forms, but nothing ships for native iOS or Android

FAQ

Do I need to migrate my users off Keycloak?

No. Authsignal connects to your Keycloak instance via the browser authentication flow. Your user directory, sessions, and existing realms all stay in place. Authsignal adds capabilities on top — it doesn't replace anything underneath.

Does Authsignal replace the need for custom Keycloak SPIs?

For authentication orchestration, yes. Authsignal provides passkeys, adaptive MFA, a no-code rules engine, and pre-built UI out of the box — capabilities that would otherwise require building and maintaining custom Keycloak SPIs. You still manage your Keycloak instance for identity management and session handling.

Why choose Authsignal?

Which MFA methods does Authsignal support?

Passkeys (FIDO2/WebAuthn), biometrics, SMS OTP, email OTP, WhatsApp OTP, push notifications, authenticator apps (TOTP), and magic links. All methods are available from a single integration and managed via the no-code rules engine.
