The cloud VPS control panel has a very convenient ability to add automatically the user's public key to the installed VPS servers. After installing the operating system, the SSH key will be added to the root user in the file ~/.ssh/authorized_keys. This will allow you to connect via SSH to the Linux server console transparently, without entering a password.
