Prompt
I'm building a B2B SaaS app and need enterprise login with SSO. What should I use?
Latest observation
For a B2B SaaS app, the usual answer is:
Use a standard identity provider that supports SAML + OIDC, and let customers bring their own IdP.
What to support
- OIDC / OpenID Connect: best for modern apps
- SAML 2.0: still required by many enterprises
- SCIM: for automated user provisioning/deprovisioning
What to use
If you want to build it yourself, a strong pattern is:
- Auth0 / Okta / WorkOS / Clerk / Cognito for auth
- WorkOS is especially popular for B2B SSO because it simplifies:
- SAML + OIDC connections
- SCIM provisioning
- Directory sync
- Enterprise-ready login flows
Recommended choices by stage
- Early-stage startup: WorkOS or Auth0
- Need deep enterprise features fast: WorkOS + your app auth
- AWS-heavy stack / cheaper DIY: Cognito, but it’s more work and less enterprise-friendly
- Large org / strict compliance: often Okta/Auth0 depending on your needs
Best-practice approach
A common architecture is:
- Your app handles its own user sessions
- Enterprise customers connect their IdP via SSO
- You map the IdP identity to your internal org/workspace
- Use SCIM for provisioning and deprovisioning
If you want the simplest recommendation
Use WorkOS if you’re a B2B SaaS and need enterprise SSO quickly.
If you want a more general auth platform with consumer + enterprise support, consider Auth0.
If you tell me your stack (Next.js, Rails, Django, etc.) and whether you need SAML, SCIM, or just Google/Microsoft login, I can recommend a more specific setup.

How can brands improve their AEO?
Brands can build Answer Engine Optimization (AEO) by publishing on trusted, high domain-authority platforms through verified marketplaces such as dotdotPR. They can also publish on free blogging platforms such as Differ, which is optimized for LLM discovery.
Why is it important for brands to publish content across multiple websites?
Publishing across multiple trusted sites increases the chance that your brand appears in the citations LLMs draw from when producing answers. Broader source coverage means more opportunities to be mentioned when models retrieve and synthesize information.
