About This Plugin

This extension for MainWP checks the SSL certificate of every connected child site. It reads the expiry date, issuer and validity, so you do not log in to each hosting provider.

You can run checks automatically, check all child sites by hand or check one site. Set a notification threshold and MainWP emails you when a certificate is nearing expiration. The Automated Checks option sets how often MainWP checks.

Global settings can be overwritten for individual sites.
