How to pass password automatically for rsync SSH command?

Question

I need to do rsync by ssh and want to do it automatically without the need of passing password for ssh manually.

Answer 1

Following the idea posted by Andrew Seaford, this is done using sshfs:

echo "SuperHardToGuessPass:P" | sshfs -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no user@example.com:/mypath/ /mnt/source-tmp/ -o workaround=rename -o password_stdin
rsync -a /mnt/source-tmp/ /media/destination/
umount /mnt/source-tmp
