WP Cron HTTP Auth


This plugin enables WP Cron on sites using HTTP Authentication.

How to use: Visit the plugin settings, enter your HTTP Auth credentials, save changes, and done.

Everything happens silently and automatically in the background.

New! Supports defined constants via wp-config.php (learn more)

Using Constants

Thanks to feedback from @nowakpiotrek, this plugin supports username and password constants defined in WordPress wp-config.php. So instead of entering the username and password via the plugin settings, you can add the following definitions to the wp-config.php file, just before the line that says, “That’s all, stop editing!” There you can add the following code:

define('WP_CRON_HTTP_AUTH_USERNAME', 'your-http-auth-username');
define('WP_CRON_HTTP_AUTH_PASSWORD', 'your-http-auth-password');

Change your-http-auth-username and your-http-auth-password to match your username and password, respectively. After saving changes, you can verify the new constants are working by visiting the plugin settings page. If the constants are working, the username and password options will be greyed out, with a message that says, “Username/Password set in wp-config.php”.


This plugin cleans up after itself. All plugin settings will be removed from your database when the plugin is uninstalled via the Plugins screen.

Restore Default Options

To restore default options, uninstall the plugin via the WP Plugins screen, and then reinstall.

Does this work for WP Multisite?

Yes, this plugin works great on Multisite.

How to test if the plugin is working?

To test if this plugin is working, follow these steps:

  1. Install and activate the excellent plugin, WP Crontrol

  2. Visit the “Cron Events” screen in the WP Admin Area (under Tools menu)

  3. Look for a warning message at the top of the screen that says:

“There was a problem spawning a call to the WP-Cron system on your site. This means WP-Cron events on your site may not work. The problem was: Unexpected HTTP response code: 401”

If the warning message is displayed, then HTTP Auth is blocking WP Cron. Otherwise, if no warning message is displayed, WP Cron is working normally.

Note: after testing it is fine to delete the WP Crontrol plugin if no longer needed.

WPCRON won't run out-of-box with HTTPAUTH active (popup credentials) - this tool allows you to enter your HTTPAUTH credentials and lets WPCRON run as normal. Perfect solve for my problem, thank you!
