Stop account takeovers without adding friction to every login
Credential stuffing, stolen passwords, and session hijacking cost you customers, revenue, and trust. Authsignal applies the right challenge at the right moment, passkeys for sensitive actions, invisible risk assessment for low-risk flows, on top of your existing identity stack.
Your IdP handles login. Authsignal stops the attacks it wasn't built for.
30%+
passkey opt-in achieved in 4 months, with a 93% passkey sign-in success rate vs 63% for legacy MFA.
<6 weeks
deployed intelligent step-up authentication on top of Duende IdentityServer, with zero migration required.
Built to catch what credential stuffing throws at you
Credential stuffing detection
Evaluate login risk in real time using configurable rules and behavioral signals. Automatically challenge or block high-risk attempts with adaptive step-up authentication.
Phishing-resistant passkeys
Eliminate shared secrets with FIDO2/WebAuthn passkeys. Cryptographic, device-bound authentication that credential stuffing and phishing cannot compromise.
Behavioral risk signals
Flag logins from new devices, unusual locations, impossible travel, and suspicious IPs. Combine multiple signals to set authentication requirements per risk level.
No-code rules engine
Fraud and security teams configure authentication policies and respond to emerging attack patterns without filing engineering tickets. Test and deploy rules in minutes.
Frequently asked questions
Authsignal evaluates risk signals at each authentication point: new device, unusual location, impossible travel, suspicious IP, and behavioral anomalies. You configure rules in the no-code engine to challenge, allow, or block based on risk level. No fixed thresholds; your team sets the logic.
Yes. Authsignal drops in on top of Cognito, Azure AD B2C, Auth0, Keycloak, Duende, and custom auth systems. No user migration, no database changes, no re-architecture. Your IdP continues to handle login; Authsignal handles step-up authentication and risk-based challenges.
Most teams have a working integration in 1-3 days using pre-built UI components and SDKs. Start with high-risk flows (password reset, high-value transactions), then expand. The rules engine lets you adjust policies in real time without code deployments.
Fraud detection tools identify risk signals. Authsignal acts on them. We sit at the authentication layer: when a login or action is flagged as risky, Authsignal challenges the user with passkeys, push, OTP, or biometrics. You can integrate third-party fraud signals into Authsignal's rules engine to combine detection with enforcement in one flow.
