Short answer SSO platforms centralize authentication into one identity provider so users log in once to access many applications via SAML, OIDC, or proprietary integrations. Best for Any company with more than a handful of SaaS apps that wants to centralize access and reduce password sprawl. When to choose Check app catalog depth, SCIM provisioning support, MFA integration, and OIDC vs SAML coverage. Prioritize coverage of your top 20 apps. When not to choose Skip SSO tooling if a broader IAM platform already covers your needs and you don't have category-specific requirements.
