Ansible prompts password when using synchronize-open source projects ansible/ansible

I’m using ansible in the following way:

ansible-playbook -f 1 my-play-book.yaml --ask-pass --ask-sudo-pass

After this I’m asked to enter the ssh & sudo passwords (same password for both).

Inside my playbook file I’m using synchronize task:

synchronize: mode=push src=rel/path/myfolder/ dest=/abs/path/myfolder/

For each host, I’m prompted to enter the ssh password of the remote host (the same that I entered in the beginning of the playbook run)

How can I avoid entering the password when executing synchronize task?
