Access Code Lite lets you require a simple URL parameter code (e.g. ‘?access_code=enter123’) before visitors can view your site. 
Simply share the private access link (e.g. https://example.com?access_code=enter123) that the plugin generates to any user who you wish to grant access. 
Ideal for development, staging, previews, or private sharing without complex authentication.
Features: 
– Set a custom access code from the plugin settings page. 
– Code can be 3–12 characters, letters and numbers only. 
– Session persistence (default): visitors only need to enter the code once per visit. 
– Logged-in users, WordPress login, password reset, admin, AJAX, and cron are always allowed.
Important: Access Code Lite is not a security plugin. 
It does not encrypt, hide, or protect sensitive data. It only adds a simple URL parameter check and should be used for low-risk scenarios like development, staging, or preview access. 
Do not rely on this plugin to secure private or confidential information.
More persistence options (cookies, tokens, etc.) will be added in future versions.

WordPress 5.5 introduced a way to differentiate between environment types (development, staging, production). This plugin shows your site’s environment type in the admin bar and the dashboard “At a Glance” widget.
<a href="https://make.wordpress.org/core/2020/07/24/new-wp_get_environment_type-function-in-wordpress-5-5/" rel="nofollow ugc">More info about the feature</a>
To gain additional control — for example, setting the environment or other values from the WP admin (when <code>wp-config.php</code> is writable) — consider installing our other plugin <a href="https://wordpress.org/plugins/0-day-analytics/" rel="ugc">0 Day Analytics</a>.

Display Environment Type

Have you ever accidentally added test content to a productive website?

You can now define a constant in your wp-config.php to distinguish between development, staging and productuion sites. To make this visible, this lean but helpful plugin adds an indicator to the admin bar and dashboard widget which helps to avoid mistakes as adding "Lorem ipsum" to your productive site. :)

Plugin works like a charm. No settings needed. Install, activate and feel happy.

Nice little helper


Five stars for Display Environment Type! 



Huge thanks to the author for creating this gem. The plugin might be small, but it's incredibly useful, doing exactly what you'd expect without any unnecessary clutter. No settings hassle – just install and get to work seamlessly.
