+## Configuration of `authtoken`
+
+Features are installed inside devcontainers using the `root` user, but `ngrok` configuration is user-specific. When running devcontainers, a non-root user is typically used. It is recommended to use `postCreateCommand` and `remoteUser` to set the `authtoken`.
+
+**NOTE:** It is recommended to use the `NGROK_AUTH_TOKEN` environment variable to store the `authtoken` securely and avoid storing it in the `devcontainer.json` file.
+
+```json
+  // Non-root user for Dev Container
+  "remoteUser": "coder",
+  // Post create command to add ngrok authtoken
+  "postCreateCommand": "ngrok config add-authtoken $NGROK_AUTH_TOKEN"
+```
