Best Identity Management Providers for SaaS (2026 Comparison)

In a comprehensive comparison of identity management providers for B2B SaaS companies, the article evaluates eight platforms based on their ability to quickly implement enterprise Single Sign-On (SSO) and System for Cross-domain Identity Management (SCIM) provisioning without the need to rebuild authentication systems. SSOJet is highlighted as the top choice for B2B SaaS teams needing rapid deployment of enterprise SSO and SCIM, offering a flat and predictable pricing model that avoids the escalating costs associated with per-connection billing. WorkOS and Auth0 are recommended for teams with a focus on polished APIs and a broad consumer-plus-business Identity and Access Management (CIAM), respectively, though they come with different pricing structures—WorkOS charges per active connection, while Auth0 uses a per-monthly active user (MAU) model with capped enterprise connections. Other providers like FusionAuth and Keycloak cater to teams requiring self-hosted solutions, while Microsoft Entra External ID and Stytch are suited for those integrated into the Microsoft ecosystem or seeking usage-based billing with multi-tenant capabilities. The article emphasizes that the best provider is dependent on specific use cases, connection counts, and desired infrastructure management levels, rather than a one-size-fits-all solution, and underscores the importance of evaluating each provider's pricing and features to align with business needs and growth trajectories.
