With the following script we monitor the SSH login on a server and send a notification via Telegram API.

Grav CMS can be used with an additional admin plugin to be able to administer the website without access to the actual file system.

This comes with potential danger, because whoever gains access to the admin plugin has unrestricted access to your Grav installation.
