Installing the plugin is easy, just follow these steps:
Access the WordPress repository by going to Plugins -> Add New on the left side of the dashboard.
Search for Sucuri in the repository.
Generate your API Key
If the website and admin email address are not correct in the API Key Generator (blue button), then you have to fix it manually from the WordPress general settings page.
If the domain name and email address are valid, the API service will generate the key. The plugin will store the key in your database, and you will receive a confirmation message regarding the success of the operation. Also, a copy of the API key is sent to the email address shown on the big blue button.
If you have any issues generating an API Key, please email firstname.lastname@example.org
