WP One Time File Download plugin will help you to grow your audience and engage more visitors on your website. A direct link to a file can be sent via multiple channels like slack, messenger, skype etc. and the user doesn’t have to visit your website to download it. WP OTFD plugin comes with a solution: it generates Unique Download Links for each visitor and once it was used to download the file, it will not work anymore. Of course, you can set a validity period for a download link – for example, from the moment that file was downloaded, the link should be valid 10 more minutes (or whatever value you want). To find out how to use the plugin, check the ‘Plugin Functionality’ section.
