FusionAuth provides a comprehensive authentication platform designed for flexibility, security, and developer ease. It supports a wide range of authentication methods including username/password, passwordless, multi-factor authentication (MFA), and social logins. FusionAuth is built API-first, allowing seamless integration into any tech stack or architecture. It supports industry protocols like OAuth2, OIDC, and SAML for secure and standards-compliant authentication. Whether deployed on-premises, in the cloud, or in hybrid environments, FusionAuth gives you full control over the user login experience while helping you meet compliance requirements such as GDPR, HIPAA, and COPPA.

FusionAuth enables Biometric Authentication through seamless integration with external identity providers or device-native capabilities that support biometrics such as fingerprint, face recognition, or voice ID. While FusionAuth doesn’t capture biometric data directly, it works with protocols like WebAuthn and FIDO2 to facilitate secure, passwordless logins using trusted device-based authentication. This approach enhances security, reduces login friction, and supports zero-trust initiatives. Developers can easily integrate biometric flows via FusionAuth’s extensible API, ensuring compliance and adaptability across platforms without compromising user privacy or data sovereignty.

FusionAuth is a purpose-built Customer Identity and Access Management (CIAM) platform that gives organizations complete control over their user identity lifecycle. It enables secure registration, authentication, authorization, and user management at scale, while supporting modern protocols like OAuth2, OIDC, and SAML. With features like social login, MFA, passwordless auth, consent management, and robust data privacy controls, FusionAuth helps businesses deliver seamless, secure digital experiences across web, mobile, and API channels. Its flexible deployment (on-prem, cloud, hybrid) and API-first design make it ideal for organizations needing customizable, compliant CIAM solutions without vendor lock-in.

FusionAuth delivers a full-featured Identity and Access Management (IAM) solution designed for modern applications and development teams. It provides centralized control over user authentication, authorization, and user data, with support for advanced protocols like OAuth2, OIDC, SAML, and LDAP. FusionAuth enables fine-grained role and permission management, multi-factor authentication (MFA), and secure access policies tailored to each application’s needs. Its API-first architecture allows seamless integration into any environment — from microservices to monoliths — while supporting on-prem, cloud, or hybrid deployments. FusionAuth empowers organizations to secure their digital assets, streamline user management, and maintain regulatory compliance with ease.

FusionAuth is a powerful identity and access management (IAM) platform designed for developers and businesses that need secure, flexible authentication. Built to integrate with any app, language, or framework, it offers all the key features — login, SSO, MFA, passwordless, SAML, OIDC, and more — fully exposed via a modern API. FusionAuth supports on-premises, hybrid, or cloud deployments, with a single-tenant architecture for enhanced security. Fast to implement and easy to scale, it helps organizations meet compliance standards like GDPR and HIPAA while giving full control over the user identity lifecycle.

FusionAuth supports robust Multi-Factor Authentication (MFA) to enhance account security and reduce the risk of unauthorized access. It includes built-in support for time-based one-time passwords (TOTP) using authenticator apps like Google Authenticator and Authy, as well as SMS-based verification. Developers can easily implement and customize MFA flows using FusionAuth’s comprehensive API, giving full control over user experience and enforcement policies. MFA can be enabled per user, per application, or based on contextual rules, making it a flexible and essential component for securing critical user data and meeting compliance standards.

FusionAuth offers robust Password Policy Enforcement to help organizations enhance security and meet compliance standards. Administrators can define custom password rules including minimum length, character complexity, expiration intervals, and history requirements. FusionAuth also supports breach detection using Have I Been Pwned to prevent the use of compromised credentials. These policies can be configured per tenant or application, giving granular control over user authentication hygiene. With a flexible API and intuitive admin UI, FusionAuth makes it easy to implement strong, adaptive password policies that protect user accounts without sacrificing usability.

FusionAuth offers secure, modern Passwordless Authentication to streamline user login while enhancing security. Users can authenticate via magic links sent to their email, eliminating the need to remember or manage passwords. This reduces friction during login, improves user experience, and minimizes common vulnerabilities like password reuse and phishing. Fully API-driven, FusionAuth’s passwordless solution integrates easily into any application stack and can be combined with other methods like MFA for added protection. It’s an ideal choice for organizations looking to modernize their authentication flow while maintaining full control and compliance.

FusionAuth supports Risk-Based Authentication (RBA) by enabling adaptive security policies based on user behavior, device, IP address, geo-location, and other contextual signals. Through its extensible architecture and event-driven webhooks, you can trigger step-up authentication, deny access, or flag anomalies in real time. FusionAuth allows full customization of authentication flows, empowering developers to build intelligent risk models and respond dynamically to threats. Combined with MFA and other controls, RBA enhances account protection without degrading the user experience—making it ideal for organizations implementing zero-trust security or compliance-sensitive environments.

FusionAuth delivers robust Single Sign-On (SSO) capabilities, enabling users to authenticate once and access multiple applications seamlessly. It supports industry standards like SAML v2, OIDC, and OAuth2, ensuring compatibility with a wide range of systems and identity providers. With flexible deployment options — including on-prem, hybrid, and cloud — FusionAuth empowers organizations to centralize identity management without sacrificing control or security. Its developer-friendly API and customizable UI make it easy to integrate SSO across your app ecosystem, accelerating implementation and improving user experience.
