 For more detailed instructions on how to install and update the dashboard, refer to [INSTALLATION.md](INSTALLATION.md).
 
+
+## Authentication
+
+Authentication is disabled by default. To enable Dashboard Authentication please follow the steps below: 
+
+**Set Credentials (Optional):**
+
+The dashboard uses `admin` and `abc` as the default username and password respectively. It's strongly recommended to change these credentials for enhanced security.:
+
+- For Docker, navigate to the `deploy` folder or `dashboard` folder if using Source and open the `credentials.yml` file.
+- Add or modify the current username / password and save the changes afterward
+  
+  ```
+  credentials:
+    usernames:
+      admin:
+        email: admin@gmail.com
+        name: John Doe
+        logged_in: False
+        password: abc
+  cookie:
+    expiry_days: 0
+    key: some_signature_key # Must be string
+    name: some_cookie_name
+  pre-authorized:
+    emails:
+    - admin@admin.com
+  ```  
+
+### Docker
+
+- Ensure the dashboard container is not running.
+- Open the `docker-compose.yml` file within the `deploy` folder using a text editor.
+- Locate the environment variable `AUTH_SYSTEM_ENABLED` under the dashboard service configuration.
+  
+  ```
+  services:
+  dashboard:
+    container_name: dashboard
+    image: hummingbot/dashboard:latest
+    ports:
+      - "8501:8501"
+    environment:
+        - AUTH_SYSTEM_ENABLED=True
+        - BACKEND_API_HOST=backend-api
+        - BACKEND_API_PORT=8000
+  ```
+- Change the value of `AUTH_SYSTEM_ENABLED` from `False` to `True`.
+- Save the changes to the `docker-compose.yml` file.
+- Relaunch Dashboard by running `bash setup.sh`
+  
+### Source 
+
+- Open the `CONFIG.py` file located in the dashboard root folder
+- Locate the line `AUTH_SYSTEM_ENABLED = os.getenv("AUTH_SYSTEM_ENABLED", "False").lower() in ("true", "1", "t")`.
+  
+  ```
+  CERTIFIED_EXCHANGES = ["ascendex", "binance", "bybit", "gate.io", "hitbtc", "huobi", "kucoin", "okx", "gateway"]
+  CERTIFIED_STRATEGIES = ["xemm", "cross exchange market making", "pmm", "pure market making"]
+  
+  AUTH_SYSTEM_ENABLED = os.getenv("AUTH_SYSTEM_ENABLED", "False").lower() in ("true", "1", "t")
+  
+  BACKEND_API_HOST = os.getenv("BACKEND_API_HOST", "127.0.0.1")
+  ```
+- Change the value from `False` to `True` to enable dashboard authentication.
+- Save the CONFIG.py file.
+- Relaunch dashboard by running `make run`
+
+### Known Issues
+- Refreshing the browser window may log you out and display the login screen again. This is a known issue that might be addressed in future updates.
