The guide explores the top five NextAuth alternatives for 2026, each addressing common challenges such as missing enterprise features, complex maintenance, limited UI components, and security gaps. WorkOS stands out as an enterprise authentication platform ideal for B2B SaaS applications, offering pre-built UI components, enterprise SSO, and SCIM provisioning. Keycloak provides a comprehensive open-source identity management solution for those seeking to self-host.
