by Combining plugins
Sometimes you may want to specify a combination of distinct authenticator and installer plugins. To do so, specify the authenticator plugin with --authenticator or -a and the installer plugin with --installer or -i.
For instance, you could create a certificate using the webroot plugin for authentication and the apache plugin for installation.
certbot run -a webroot -i apache -w /var/www/html -d example.com
