     **Push Notifications**
 
-    If you would like to take advantage of having push notifications automatically keep your bitwarden client applications synced in real time you can choose to use the bitwarden push notification relay service. This relay service is provided by external bitwarden servers. You should ensure that your machine can communicate with the `https://push.bitwarden.com` endpoint. Your bitwarden installation will POST **non-sensitive data** (reference ids) to the relay service which will then notify the bitwarden client applications to "phone home" for an update back to your installation.
