Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Authsignal is an MFA and passkeys-as-a-service platform for consumer-facing applications. It supports web, iOS, Android and API deployments, adding passkeys, adaptive MFA, OTP verification and push authentication to an existing identity provider or custom identity stack. Its audience is engineering and product teams in industries such as financial services, healthcare, payments and loyalty, particularly where risk-based authentication and mobile verification are central requirements.
The published plans show a paid product with a 30-day full-feature trial and no free plan. Professional costs $499 per month and includes risk-based adaptive MFA, passwordless authentication, email and SMS OTP, TOTP, push authentication, a FIDO-certified Passkey Server, hosted UI flows, SDKs, SOC 2 Type 2, base-level SLAs and SSO. Enterprise uses volume-based pricing and adds enterprise SLAs, a DPA, flexible terms, advanced compliance due diligence, dedicated support channels, an account manager and Terraform infrastructure-as-code support. This structure suits organizations able to budget for a production authentication service, while smaller teams seeking a free starting tier should look elsewhere.
Authsignal’s breadth is its main distinction. Alongside passkeys and push verification using mobile apps and public-key cryptography, it provides a no-code rules and policy engine, session and authenticator management, and webhook event delivery with signature verification. Integration coverage includes Amazon Cognito, Auth0, Azure AD B2C, Keycloak, OpenID Connect, React, Node.js, Java, Python, PHP and other listed environments. Choose Authsignal when a consumer-facing product needs several authentication methods and adaptive policies across web and mobile. Choose an alternative if the requirement is limited to a basic single-factor or low-cost MFA component.
