Answer 1

You can use sshpass, but better to use ansible. Example of sshpass usage:

# vim server.list
192.168.0.100
192.168.0.101

# apt-get install sshpass
$ vim script.sh
#!/bin/bash
while read -r line
do
    echo "running $line"
    SSHPASS=PASSWORD sshpass -e ssh-copy-id USERNAME@"$line" -o "StrictHostKeyChecking no"
done < "server.list"

Run script:

$ sh script.sh
running 192.168.0.100
...
Number of key(s) added: 1
running 192.168.0.101
...
Number of key(s) added: 1

Install expect,

#script.sh    
#!/usr/bin/expect -f
    username=user
    password=pass
    for HOST in $(cat $1)
            do
                    echo "ssh $username@$HOST"
                    expect "Password:"
                    send "$pass\r"
            done
