Thank you for your post. At present, we indeed do not support the direct-URL (token-only, no-password) DDNS update method. However, your request has been forwarded to the Requests & Suggestions module, which means it may be evaluated for inclusion in a future release.Your feedback and ideas are truly valued. At this point, we can’t confirm whether this enhancement will be rolled out  or provide a timeline, but rest assured, I’ve noted your request and will forward it to the development team. If you have any additional suggestions, don’t hesitate to drop them here; we’re always glad to pass them along.
