+## 1.32.0

+### What changed?
+
+N8n auth cookie has `Secure` flag set by default now.
+
+### When is action necessary?
+
+If you are running n8n without HTTP**S** on a domain other than `localhost`, you need to either setup HTTPS, or you can disable the secure flag by setting the env variable `N8N_SECURE_COOKIE` to `false`.
