Knock First makes it easy to password protect an entire WordPress website with one shared password. It is ideal for private sites, staging websites, client previews, coming-soon pages, and launches.
The plugin is disabled by default. After activation, open Settings > Site Password, choose a password, and enable protection.
Features:
This plugin is a simple privacy gate. It is not a replacement for WordPress user accounts, server-level access control, or another security system when protecting sensitive or regulated data. Public files already uploaded to the Media Library may remain reachable by their direct URLs, and another plugin can expose data through its own custom endpoints.
