I need a lightweight, hard-coded login gate on a single WordPress page. I will supply one username and one password; the check should be performed against these credentials only, not against the site’s user database. When the visitor enters the correct pair the page should simply refresh and reveal the protected content. No visual redesign is required—WordPress’ default form styling is fine. Although my preference is for the content to unlock on the same URL, I already have an alternative destination URL on hand in case your approach requires a silent redirect. Please implement this as cleanly as possible: a small custom plugin or a few lines added to my child theme functions is perfect, provided it’s secure (nonce, session handling, and basic brute-force protection). Deliverables: • Working login form integrated into the specified page • Clear install/update instructions and the code files If you need any additional details, just let me know—I can give access and the page URL right away.
