Hello,
By default, SFTP uses the SSH protocol to authenticate and establish a secure connection. Because of this, the same authentication methods are available that are present in SSH.
Although passwords are easy to use and set up by default, we recommend you create SSH keys and transfer your public key to any system that you need to access. This is much more secure and can save you time in the long run.
Please see this guide to set up SSH keys in order to access your server if you have not done so already.
If you can connect to the machine using SSH, then you have completed all of the necessary requirements necessary to use SFTP to manage files. Test SSH access with the following command:
ssh sammy@your_server_ip_or_remote_hostname

Hope that this helps!
Regards,
Alex

SFTP is a secure way to transfer files between local and remote servers. Much more secure than FTP, this protocol uses an SSH tunnel to establish a connection and uses encryption to transfer files in an interactive session.
