Something like this:

#!/bin/sh
in_file=/path/to/input/file
out_file=/path/to/output/file
out_address=""
out_passwd=""
rm -f $out_file
while read input_field should_be_null; do
  if [ -z "$out_address" ]; then
    out_address=$input_field
  else
    out_passwd=$input_field
    echo "$out_address $out_passwd" >> $out_file
    out_address=""
    out_passwd=""
  fi
done < $in_file
exit 0
