+### Specify 7 - Single Sign-On (SSO) Configuration for Feide
+
+Specify 7 supports integration with institutional identity providers using Single Sign-On (SSO). This guide outlines the steps required to configure SSO using Feide, Norway’s federated educational identity provider.
+
+### Benefits of Using Feide for SSO
+
+Integrating Specify 7 with Feide provides the following advantages:
+
+- Reduces the number of required logins for users, enhancing user experience.
+- Improves institutional security by utilizing a single set of secure credentials.
+
+### Configuration Steps
+
+1. **Obtain Feide Client Credentials:**  
+   An institutional IT administrator must register Specify 7 as an application with Feide to obtain:
+   - Client ID
+   - Client Secret
+
+2. **Configure Specify 7 Server:**  
+   Edit the `specify_settings.py` configuration file on your Specify 7 server to include Feide as an OAuth provider:
+
+```python
+OAUTH_LOGIN_PROVIDERS = {
+    'feide': {
+        'title': "Feide",
+        'client_id': "YOUR_FEIDE_CLIENT_ID",
+        'client_secret': "YOUR_FEIDE_CLIENT_SECRET",
+        'config': "https://auth.dataporten.no",
+        'scope': "openid email profile",
+    },
+}
+```
+Replace `YOUR_FEIDE_CLIENT_ID` and `YOUR_FEIDE_CLIENT_SECRET` with credentials provided by Feide.
+
+3. **Inviting Users through Specify 7:**  
+   Collection administrators can link Feide accounts by generating invitation links for new users:
+   - Navigate to the **Security and Accounts** panel in Specify 7.
+   - Create a new user account and select the option to generate an invitation link.
+   - Share this link with the intended user.
+
+4. **Associating Feide Account with Specify User:**  
+   Users clicking the invitation link will be prompted to associate their Feide account with their Specify 7 user profile:
+   - Click the invitation link received.
+   - Select "Feide" as the login option.
+   - Authenticate via Feide when prompted.
+
+5. **User Login Experience:**  
+   Once configured, the Specify 7 login screen will display an option for Feide authentication alongside standard username/password login.
