Enterprise SSO authentication is a way for employees or members of an organization to log in once and access multiple applications without signing in again each time.
Common protocols
- SAML 2.0: Older, still very common for web apps
- OpenID Connect (OIDC): Modern, built on OAuth 2.0, widely used for new apps
- OAuth 2.0: Mainly for authorization, often used alongside OIDC for login
- Kerberos / LDAP / Active Directory integration: Common in internal enterprise environments
Typical flow
- User clicks “Sign in with company account”
- App redirects to the enterprise Identity Provider (IdP), such as:
- Microsoft Entra ID (Azure AD)
- Okta
- Google Workspace
- Ping Identity
- Auth0
- User authenticates with the IdP
- IdP returns an assertion/token to the app
- App validates the token and creates a session
Benefits
- Centralized access control
- Easier onboarding/offboarding
- Better security with MFA and conditional access
- Reduced password fatigue
- Single login across multiple apps
Enterprise features often included
- Multi-factor authentication (MFA)
- Conditional access policies
- Role-based access control
- User provisioning/deprovisioning via SCIM
- Audit logs and compliance reporting
- Support for Just-In-Time (JIT) provisioning
If you’re implementing it
You usually need to decide:
- Which protocol to support: SAML or OIDC
- Which IdPs you want to integrate with
- How you’ll map groups/roles/claims
- Whether you need automatic provisioning with SCIM
- How to handle logout, session expiration, and account linking
If you want, I can also provide:
- a step-by-step SSO implementation guide
- a comparison of SAML vs OIDC
- or sample code for a specific stack (Node.js, Python, Java, .NET, etc.)
