Milkshake is a plugin for WordPress that disables the shake effect that occurs when a user types their login credentials incorrectly on the WordPress login page. This plugin is useful when you’ve customized the WordPress login page for a project and the shake effect just doesn’t fit. Maybe you find the shake effect annoying, or maybe you suffer from seizures and want one less place to worry about one being triggered. Milkshake is also useful in that case.
This plugin has no options screen. Simply activate it and when your login information is accidentally typed incorrectly, there’s no more shaking.
to use this plugin, download the file and either unzip it and manually upload milkshake.php to your wp-content/plugins directory. Or, download the zip file and use the upload plugin screen to upload the zipped file. Then, activate the plugin.
