The Ahrefs SEO WordPress Plugin is a part of Ahrefs toolset, classified under Integrations. You need an active account at ahrefs.com in order to use the plugin's features without any restrictions since that entitles you to use Integrations. Refer to the section below to find out how many integration rows the plugin consumes. 

If you don't have an active Ahrefs account, you can opt for a free Authorization code during the plugin activation. The disadvantage is that the free code is temporary and expires every few weeks, so you’ll have to reconnect the plugin each time this happens.
