How to enable login email alert on server – WHM and SSH login alert

We can setup an email alert for every login attempt via SSH and WHM to server. This is an important security concern for server owners to protect the server from unknown login attempts. By setup this email alert, every server owner will get an email alert regarding the login attempts to server every time. We can set up the WHM login alert via CSF and also the SSH login attempt by editing the “.bashrc” file on the server.
