Enterprise SSO in Elixir Phoenix: How to Add SAML Auth With SSOJet in 2026

The Verizon 2025 Data Breach Investigations Report underscores the critical need for secure authentication, particularly for B2B SaaS teams using Elixir and Phoenix, as 81% of breaches are linked to weak credentials. Many enterprise customers demand Single Sign-On (SSO) before finalizing contracts, yet Elixir lacks a mature SAML library, making it difficult for developers to implement SSO securely. SSOJet offers a solution by providing an OpenID Connect (OIDC) hosted page flow that simplifies integration by handling SAML parsing, assertion validation, and more, allowing Phoenix applications to redirect users to SSOJet's authorization page. This approach avoids the complexities and risks of building custom SAML parsers, facilitates secure user provisioning, and offers flat-rate pricing without per-user charges, unlike competitors like Auth0 and WorkOS. Despite Elixir's strengths in other areas, the enterprise authentication ecosystem is limited, making services like SSOJet vital for secure, scalable, and maintainable SSO integration.
