Configure enterprise-grade access control for Langfuse with role definitions, scoped API keys, project-based access, SSO integration, and RBAC audit logging.
Define five roles (Owner, Admin, Member, Viewer, API Only) with granular permission maps for dashboard, traces, settings, members, billing, and data deletion.
Generate API keys with specific permission scopes, project restrictions, IP allowlists, and custom rate limits.
Build a project access controller that maps users to roles per project, with privilege escalation prevention.
Map IdP groups to Langfuse roles via SAML assertions. Enforce email domain validation.
Log all member additions, removals, role changes, and permission denials. Alert security team on denied access.
See detailed implementation for advanced patterns.
