Works with the identity providers your customers already use
Every SaaS team builds auth. None of them want to.
Months of engineering
SSO alone can take weeks. Add SCIM, MFA, user management, branding, and custom domains — it never ends.
Constant maintenance
Token rotation, certificate renewal, security patches, compliance audits. Auth is never "done".
Enterprise blockers
Your biggest prospects need SAML SSO and SCIM provisioning. Without them, deals stall at the security review.
Go live in three steps
Create your account
Pick a slug and choose a plan. You get a fully configured auth server at {slug}.authagonal.io — ready in seconds.
Add your application
Register your redirect URIs, configure token settings, and copy the OIDC discovery URL into your app.
Ship it
Your users get enterprise-grade login with SSO, MFA, and everything else built in. You get your roadmap back.
