Hide Plugins is a light-weight plugin that gives a single admin user the ability to hide plugins prevent them from being activated, deactivated, or deleted by clients and other users, including administrators. By activating Hide Plugins, you will be able to see all plugins and a toggle to hide each plugin from other users on the Plugins page. Hide Plugins will always remain hidden.
Note that the dropdown on the Edit Plugins page will not be affected, since it does not have a filter to hook into. Hidden plugins will remain active, so traces of the plugin in areas other than the Plugins page (like options pages in the admin menu) will still be visible. If you also want to hide menus, we recommend using <a href="https://wordpress.org/plugins/admin-menu-editor/" rel="ugc">Admin Menu Editor</a>.

Pressing the set keystroke combination will activate Hidden Login, either displaying a modal login window or redirected to the admin area if you are already logged in. Visit the Hidden Login Options to set what pages are enabled (All Pages or Homepage Only) and set your desired activation keystroke combination.
