This document will use Okta as the SSO identity provider to demonstrate how to enable OAuth2 authorization protocol for Dify Enterprise. By enabling this feature, the enterprise login page will use a unified identity authentication entry to enhance security. For enterprise internal users, there’s no need to enter complex passwords - they can log in using organizational accounts to pass verification, simplifying the login process.
This document will mention internal users and external users. The following distinctions are made: Internal members: Members registered within the Dify Enterprise workspace or added through the admin backend. External users: Members not within Dify Enterprise

​
1. Create a New Application in Okta

  1. Access the Okta administrator backend page, navigate to the Applications page. Click the Create App Integration button, select OIDC login method and Web Application application type.
  1. Fill in the application name according to the page prompts and define the authorization scope according to requirements.
  • The Sign-in redirect URIs field needs to be filled with the Dify Enterprise Callback URL. Please refer to the section below for how to obtain it.
  • Leave the Sign-out redirect URIs field empty.

2. Obtaining Callback URL

According to the required SSO scope to be enabled, Callback URLs differ. System administrators need to fill the Dify Enterprise Callback URL into the corresponding GitHub OAuth2 application to complete the creation process.
Click Admin Backend → Identity Authentication → Member → SSO Identity Provider → New Identity Provider → New OAuth2 Provider, and view the Workspace Callback URL at the bottom.It usually follows this format:
https://[your-dify-enterprise-url]/console/api/enterprise/sso/oauth2/callback

4. Enable SSO Mandatory Authentication (Optional)

System administrators can enable SSO Enforcement options for the following two scenarios to enable mandatory authentication:
