SSO Enforcer for Jetpack works with Jetpack Secure Sign-On (SSO) to:
wp-login.php visitors directly to WordPress.comwp-login.phpThe plugin only enables enforcement when Jetpack is installed, the site is connected to WordPress.com, Jetpack WordPress.com login (SSO) is enabled, and the enabling administrator is linked to WordPress.com.
Deactivating or deleting the plugin immediately stops enforcement and restores your previous Jetpack SSO behavior.
