FAQ

Do I need to migrate my users off Auth0?

No. Authsignal connects to your Auth0 tenant via Auth0 Actions. Your user directory, sessions, and existing authentication flows all stay in place. Authsignal adds capabilities on top — it doesn't replace anything underneath.

Can Authsignal give me passkeys without an Auth0 enterprise-tier upgrade?

Yes. Auth0's native passkey support is gated behind enterprise pricing. Authsignal provides FIDO2-certified passkeys, adaptive MFA, and a no-code rules engine on top of your existing Auth0 plan — no tier upgrade required.
