Hi @bahus,
For reasons of why we’ve changed the free signup process please take a look at the following blog post:?https://www.wordfence.com/blog/2022/11/wordfence-7-8-0-announcement/
Wordfence is very much still free and not a trial period. Any sites that installed the plugin before the free license changes in late 2022 will have had a key generated automatically by Wordfence, which would have continued to work.
However, new installations or reinstallations will require the following process (there’s a video in addition to text instructions): https://www.wordfence.com/help/api-key/#installing-your-free-license-key
There’s no limit to the amount of free sites a single email address can register, so if you have multiple sites to manage, you won’t be restricted in any way from getting the plugin set up.
Many thanks,
Peter.
