What should I use for enterprise login: SAML or OIDC?

For most new enterprise login implementations, choose OIDC (OpenID Connect).
Quick rule of thumb
- Use OIDC if you’re building a modern web app, SPA, mobile app, or API-based system.
- Use SAML if you need to integrate with older enterprise identity providers or you’re dealing with legacy B2B enterprise SSO requirements.
Why OIDC is usually the better default
- Modern and simpler than SAML
- Works well for web, mobile, and APIs
- Uses JSON/JWT, which is easier to handle than XML/SAML assertions
- Better fit for microservices and cloud-native apps
- Easier developer experience and generally less integration pain
When SAML is still the right choice
- Your customer’s IdP only supports SAML well
- You’re integrating with legacy enterprise environments
- You need compatibility with existing SSO setups that are already SAML-based
- Your org already has a mature SAML infrastructure and wants minimal change
Practical enterprise recommendation
If possible:
- Support both
- Make OIDC your primary/default
- Add SAML for enterprise customers who require it
Short answer
- New product / new integration: OIDC
- Legacy enterprise compatibility: SAML
- Best enterprise strategy: OIDC first, SAML as optional support
If you want, I can also give you a decision matrix or explain this specifically for web apps, SPAs, mobile apps, or B2B SaaS.
