Single Sign-On

Enterprise authentication for secure access to your docs
Enterprise feature

This feature is available only for the Enterprise plan. To get started, reach out to support@buildwithfern.com.

Fern’s Single Sign-On (SSO) is an enterprise feature that lets your team securely access your docs through your organization’s identity provider.

SSO does not support Role-Based Access Control or API Key Injection.

What SSO unlocks

When SSO is enabled for your organization, authenticated users of Fern can:

  • Use the Fern Editor: Make edits to your docs from the browser
  • Send Authenticated Preview Links Only authenticated users can view preview links

How it works

Fern’s SSO integration allows your team to use their existing corporate credentials to access your Fern Docs site.

Supported identity providers

Fern supports SSO integration with any identity provider that implements industry-standard protocols:

  • SAML 2.0: Compatible with providers like Okta, OneLogin, Azure AD, and others
  • OIDC (OpenID Connect): Works with Google Workspace, Auth0, and other OIDC-compliant providers

Setting up SSO

Reach out via Slack or contact our team to begin the SSO setup process. Fern will work with one of your security administrators to connect to your identity provider.
