If you want SSO without maintaining custom auth code, the usual answer is to use a managed Identity Provider (IdP) or an auth platform that supports standard protocols like OIDC/OAuth2 and SAML.
Good options:
- Auth0 — very common for app SSO, easy to integrate, supports social + enterprise SSO
- Okta — strong enterprise SSO/IAM, good if you need B2B or workforce auth
- AWS Cognito — useful if you’re already on AWS, though a bit more fiddly
- Firebase Authentication / Google Identity Platform — simpler for consumer auth
- Microsoft Entra ID (Azure AD) — best if your users are in Microsoft ecosystems
- Clerk / WorkOS — popular for modern SaaS apps; WorkOS is especially good for enterprise SSO
- Keycloak — open source, but you still maintain it yourself, so less “no custom auth code” and more “no vendor lock-in”
If your goal is specifically:
- “I want enterprise SSO for a SaaS product” → WorkOS or Auth0
- “I want workforce SSO for internal apps” → Okta or Entra ID
- “I want the least code and easiest setup” → Clerk or Auth0
- “I already have AWS infrastructure” → Cognito
What to choose
If you want to avoid building auth flows yourself, I’d usually recommend:
- WorkOS if you need B2B enterprise SSO
- Auth0 if you want a general-purpose, widely supported solution
- Okta if your customers are enterprise-heavy
If you want, I can also recommend the best option based on your stack (React/Next.js, backend language, SaaS vs internal app, B2B vs B2C).
