+#### Authentication
+
+When using the Spacedrive server you can use the `SD_AUTH` environment variable to configure authentication.
+
+Valid values:
+ - `SD_AUTH=disabled` - Disables authentication.
+ - `SD_AUTH=username:password` - Enables authentication for a single user.
+ - `SD_AUTH=username:password,username1:password1` - Enables authentication with multiple users (you can add as many users as you want).
