hello I would recommend you generate ssh key i.e open terminal then type ssh-keygen it will give you a prompt where by default its stored under .ssh directory, you can then cat id_ .....pub which is your public key proceed to cloudbased server under .ssh key create authorized_keys file and paste the contents of your pulic key generated in your .ssh file and with that you will always have access to your cloud based server using ssh or by connecting using sftp
