You should not use ftp protocol for anything where you enter your login and password, and then send it is clear on the net. Just start wireshark if you want to know why.

Use ssh, scp or sftp, which is all based on ssh-protocol, which encrypt passwords, and also check against man-in-the-middle attacks (some one fake your server, and forward everything you write to the server, while it log your login and password, which is easy with ftp, and really hard with sftp, scp or ssh).

You can even set up ssh keys in ~/.ssh so you don’t need to re enter passwords/credentials on each connection after the first (if you run ssh-agent that handles user certificates you have added with ssh-add command).
