title: Bash scp several files password issue
body: <p>I am trying to copy several files from a remote server into local drive in Bash using scp.
  Here's the part of the code</p>
  
  <pre><code>scp -r -q $USR@$IP:/home/file1.txt $PWD
  scp -r -q $USR@$IP:/home/file2.txt $PWD
  scp -r -q $USR@$IP:/root/file3.txt $PWD
  </code></pre>
  
  <p>However, the problem is that EVERY time that it wants to copy a file, it keeps asking for the password of the server, which is the same. I want it to ask only once and then copy all my files.</p>
  
  <p>And please, do not suggest rsync nor making a key authentication file since I do not want to do that.
  Are there any other ways...?
  Any help would be appreciated</p>
