Authagonal is authentication infrastructure for SaaS companies. Hosted login on your own domain, with your branding, wired into your product in minutes instead of the months it takes to build identity in-house. Most auth vendors meter permission. They gate SSO, SCIM, and MFA behind enterprise tiers and charge per-connection fees for features that cost almost nothing to provide. We don't. Authagonal ships every security feature at every plan — you pay for scale and support, not for unlocking the basics. What you get, on day one and on every tier: • SSO via SAML and OIDC, with no per-connection fees • SCIM provisioning, MFA, and role-based access control • Audit logs, custom domains, and per-tenant branding • A management portal your customers' own admins run themselves Switching providers? Migrate from Auth0 or self-hosted Duende with your existing password hashes intact, so the cutover is invisible to your users. No mass password reset, no flood of support tickets. Built for multi-tenant B2B SaaS that needs the enterprise security checklist without an enterprise-sized bill or a quarter of engineering time. Pay for how big you get, not for which switches you're allowed to flip.
