Overview of authentication options
Fern supports three ways to restrict access to your documentation:
- RBAC — Control which content different users can see. Supports API key injection via JWT or OAuth. Recommended for most use cases.
- SSO — Require login without role management. Good for internal docs where all users see the same content.
- Password protection — A single shared password for the entire site. Good for pre-release docs or basic access restriction.
