Why does Vagrant require a password when syncing?

Question

linux

Hello, I have a problem syncing in Vagrant using rsync. For example, if I am editing a file on the host, then each time I have to enter the password in the terminal in order for the file to be synchronized.

[email protected]:~/Vagrant/nominato_ubuntu_machine$ vagrant rsync-auto
==> default: Doing an initial rsync...
==> default: Rsyncing folder: /home/user/Projects/nominato/ => /home/ubuntu
ubuntu @127.0.0.1's password:
==> default: Watching: /home/user/Projects/nominato
==> default: Rsyncing folder: /home/user/Projects/nominato/ => /home/ubuntu
[email protected] 0.1's password:

How can I make it so that no password is required and everything is synchronized on the fly?
