About FusionAuth
FusionAuth is a customer identity and access management (CIAM) platform built for developers and security teams. It supports login, registration, SSO, MFA, and standards-based protocols, with hybrid or dedicated deployments that let you develop and test identity features where you build your apps.

Key Features
To understand its value in practice, teams integrate FusionAuth to secure access across multiple apps and services, using a single solution for sign-in, access control, and user data:
Registration & Login
Flexible options including passwords, passwordless, SSO, and MFA, with OAuth2, OpenID Connect, and SAML v2 support for secure sign-in.
Single Sign-On
Streamlines cross-app access while maintaining strong authentication and centralized user management.
Passkeys
Supports passwordless login using platform passkeys and biometrics, reducing password resets.
Multi-Factor Authentication (MFA)
Adds an extra verification step to protect accounts and can be configured per user or group.
API Authorization
Fine-grained access control to protect APIs and scale securely across services.
Role-Based Access Control (RBAC)
Define roles and permissions to limit access to features and data.
Summary
Best for product engineering teams building customer apps, security/compliance teams managing access, and operations teams running multi-app deployments.
