| Overview | Auth0 provides authentication and customer identity management (login, MFA, SSO, user management) via SDKs and APIs. Okta acquired Auth0 in 2021, and it now operates as the Auth0 Platform alongside Okta's workforce-identity products. | FusionAuth is a downloadable CIAM server with a free, unlimited-user Community edition, offering OAuth2/OIDC/SAML, MFA and passwordless login for any language or stack. | SuperTokens provides open-source, self-hostable authentication — email/password, social login, passwordless, MFA, session management, and RBAC — plus a managed cloud service that's free up to 5,000 monthly active users and usage-priced beyond that. |
