How to add password input to shell script?

Question

*nix-like systems

Hello.
I used a similar code to download archives from the server

#!/bin/sh
HOST="host"
PORT="21"
USER="user"
PASSWD="pass"

FILE="dir"
UFILE="dir"
ftp -n $HOST $PORT <<EOF
quote USER $USER
quote PASS $PASSWD
bin
get $FILE $UFILE
quit
EOF

exit 0

But as the files began to grow, I realized that this script has its limitations and decided to look towards ssh.
scp [email protected]:/dir /dir
But here I still need to transfer a password, and here Google let me down, I can’t find a single example with a password, who can tell me how to do it right similar request from a script?
