FAQ
- Why do I need to create an account at wpscanner.io?
-
Scanning a site for performance and security issues is a resource intensive process, which can take time to complete. With a free WP Scanner account we offload the scanning process to our own servers, so as not to impact site performance. Doing so also allows us to detect additional performance and security issues, which we couldn’t from the plugin alone.
- Is WP Scanner free to use?
-
Yes, WP Scanner is completely free to use for 1 site. If you need to scan additional sites, premium plans are available.
- Is WP Scanner secure?
-
Absolutely! No sensitive data is sent to our servers.
- Will this plugin impact the performance of my website?
-
No, it will not.
